This came up in the Jeep thread:

So this is a thing.
all speakers work and I tested the SD card function as well. The radio function seems a little weak but what can you expect for a $30 stereo?
And I've already read enough to know Pyle isn't the way to go. I need a stereo for my Jeep (heavy offroad use, so CD player is ... basically useless), and I'd like to find something like:

Are there any better stereos like that? Ideally, I'm looking for AM/FM, (multiple mono/stereo) AUX in, USB, and (maybe) an SD card. And I'm willing to spend more than $30 to get a good one.

Basically, I want to have my ipod plugged in while driving, have the option to switch to a USB stick, and also have a ham radio (two mono 1/8" outputs) plugged in. If necessary, I can unplug the iPod to plug in the ham, but I'd like to be able to leave both plugged in. Also, I can adapt the mono outputs to stereo, so it really doesn't matter if it has two monos and a stereo or two stereos. I'd prefer at least one be on the back of the unit.
Any suggestions?

If it matters, the Jeep has 4 (~4"?) speakers, two in the front doors, two in the rear, and I just picked up a set of Infinity references to replace whatever poo poo was in them before. I'm not likely to add a subwoofer or more speakers or anything, and putting an amp in would also be ... unlikely.

Bonus points for less flashy lights and/or red display.

Is there any reason this microphone wouldn't work with this headunit?

It says it's for Clarion only, but as far as I can tell, it only has the one connection (the 3.5mm mic jack), which is what the stock mic connects to the Kenwood headunit with. I've obtained a HU without a mic, and in looking for one, this one looks pretty nice. In particular, I like the noise cancelling aspect, since this is for use in a rather ... disharmonious vehicle.

If it won't work, any other suggestions?

I put it in my project thread but I'll mention it here. I grabbed this for now off eBay secondhand. That's why the trim ring thing is missing. The display and controls are nice and simple. I hat to tie the positive rails together and run them off an always on source because the car has an ignition circuit but no accessory circuit. Having the main always on wouldn't cause any extra drain would it? I know it's a per case thing but a general answer if possible would be good. If I suspect anything I'll just put a multimeter inline to check the quiescent current.

Having the stereo always on will absolutely cause extra drain. I would say unless you've got a robust electrical system (ie, big rear end battery), you're going to kill your battery in short order leaving it on.

Theoretically, as long as you're switching it off somehow, it should be fine, then.

I currently have a Kenwood KDC-X996 in my Jeep, and it has this random recurring problem - it will suddenly stop playing any audio sources. It will still beep when you press a button, so it's pushing some kind of signal to the speakers, but it won't play any audio.

The last time this happened, I pulled the head unit out, unplugged it completely, didn't see any change, pulled the fuse at the back, and replaced it (as in, the fuse was fine, I took it out and put it back in), and the audio started working again. It's been about a month and it's doing it again.

So, I'm curious about what could cause this, but I'm mostly considering it an excuse to upgrade. I'm mostly happy with the feature set, but there are definitely some gripes I have about it, so I'm hoping for recommendations.

I mostly just hook my iPhone up to this and play audio (music, audiobooks, Waze) through it - so I need USB input, and I like that the Kenwood had a wire running from the back. I need it to be able to hook up to RCA outs, and I value great sounding music, but I don't know much about setting it up - so I guess I need "a clean signal" or "powerful output", but I don't really know what that looks like.

I need manual equalizer, and knobs for it would actually be cool, but I don't know if that's a thing. Bluetooth for audio, and phone, would be nice.

I'd also like it if it had red display, but I would use something else if the other features are there. Budget ... Ideally $250 or less, I'm willing to spend more if necessary for something good.

Edit: oh yeah, and it's a 1.5 DIN slot, but 1 or 1.5 would be fine.

I'm a big fan of the sony mex-xb100bt. It covers a lot of the features you are looking for except manual equalizer buttons which Wil most likely be impossible to find in a modern head unit.

The Sony should give you quite a bump in power which should give you better sound over the Kenwood you currently have.

As for your Kenwood, it sounds like something internally is going bad. Obviously not a power issue. Sounds like the dac (digital to analog converter) is going bad if I had to guess. Since digital sources stop playing but button presses produce audio. I'm guessing the button presses are analog audio so they don't use the dac and thus produce sound. Just a hunch though.

The Pioneer DEH-80PRS has pretty much everything you're looking for and is around your price range. Not as much power as the Sony, but it sounds like you might be using external amps already anyways.

Got my DEH-80PRS installed, loving it (except the keypress beep that I can't disable, but that's no biggy). The Auto-level/time adjust/EQ is pretty amazing - I installed a few more tweeters and was trying to get them to sound right, ended up running that and it fixed them up very well. Only problem - it's now running a ton of bass through the front 6.5" speakers. Can I lower that without undoing the Auto adjustments?

Ok, I know the advice is ignore the rears, but since I don't have the "something needs to be neglected or skipped" clause, I'm looking for some advice.

The vehicle is a 2000 Jeep Cherokee. So far, it's got (old, german) MB Quart speakers up front - a 6.5" speaker in each door, and a tweeter on each end of the dash. It also has these Pyle tweeter sets on the visors. I'm adding a powered subwoofer this weekend, and while I've got to finish that before I really make any decisions, I'm trying to figure out what to put in the rear roof speaker locations. It's currently got two Infinity drivers, which are labeled as a 6" woofer. At the very least, I'd like to add an amplifier to drive the rears, and realistically, I'd be very open to spending a bit to do amplifier, crossovers, and some sort of speakers, in the name of better sound quality and more volume.

Currently, the front sounds pretty good. There's a very definite increase in volume and clarity over the original old & busted speakers and even, indeed, the infinity speakers I swapped in after that. I think that I'm happy with how the front sounds, and I'm not sure what the best way to add to that is - should I just amplify the existing 6" woofers? Should I get 6.5" 2 ways?

I would like to get a recommendation on amplifier (/ crossovers if necessary) as well. Up front, I've got a very small Alpine amp driving everything, and it seems to do quite well. I might be able to find another such amp on eBay, but it dates back to at least the early 90s, so it's not something I can buy on amazon or crutch field.

So: What should I put in my rear 6.5" speaker spots? What amp should I use to run them? Are two ways worth it, and if so, what kind of crossover should I use?

I just jumped ship from iPhone to Android so my Alpine CDA-117 will no longer work with my phone unfortunately. It might be for the best because it was beginning to have all sorts of intermittent moments where it wouldn't recognize my phone and would keep disconnecting/reconnecting. Not sure if it has something to do with the cable or otherwise but I'm ready for a better solution now anyway.

Unfortunately it looks like Alpine more or less doesn't care about Android support so I guess my best bets are Pioneer or Kenwood.

Can someone point me in the direction of a solid Single DIN deck that will play nice with Android (primarily listening to spotify and podcasts but also some music stored on the device).

It looks like Bluetooth has gotten a lot better since I was last stereo shopping so I'd be really interested in hearing about people's experiences with Aptx or A2DP.

These are the two Kenwoods I was looking at:
https://www.amazon.com/Kenwood-KDC-X599-Bluetooth-Receiver-Compatibility/dp/B00QCVWDG0
https://www.amazon.com/Kenwood-KDC-X700-eXcelon-Receiver-Bluetooth/dp/B01D52V4TA

My only real requirements are: don't look hideous, sound good, and accept CD's (for nostalgia kicks)
It would definitely be preferable to have USB out the back so that I could run the lead down under the center console to a phone mount or somewhere that it wouldn't have to be hanging off the deck.
I've been very happy with this:

Pioneer DEH-80PRS Mobile CD Receiver with 3-Way Active Crossover Network, Auto EQ and Auto Time Alignment https://www.amazon.com/dp/B006Y44DAY/ref=cm_sw_r_cp_api_lDZZxb4X8FMCJ

My biggest concern was "sounds good", and it does. It offers a huge amount of adjustability and control over outputs and made my mishmash of speakers sound great together. It's in one car already and is going in the other shortly. Only gripe is that it has a key beep that can't be suppressed, but that's no biggie.

Assuming Velocibacon is right (I don't know), you might be better off doing this in lieu of the amp and sub:

I have one of these in my 4x4 and it pretty much nails exactly what you're describing - it's not going to win competitions, but it sounds good and it's more than adequate (I think I have it turned all the way or almost all the way down and it's still quite sufficient).

Planet Audio P8UAW 8 inch 800-watt Amplified Subwoofer System https://www.amazon.com/dp/B00TKGWCGA?ref=yo_pop_ma_swf

It’s not going to win an SPL competition, but it puts out tons of bass, sounds good, and it’s worked really well. Has lots of adjustments if your head unit doesn’t handle it.

Yep, like he said, flat piece of metal in those corners.

I like to jiggle the head unit ( :q: ) to free it as I work at each one. There's probably a catch at each corner, and it won't come out until you release all of them, so angling the head unit back and forth can help each one stay unhooked once it is released.

I don't know if there's an up or downside to having two fuses in the line, but personally, I'd have skipped the amp wiring kit and just used some appropriate wire to extend the harness as needed (if at all). Basically, you probably didn't need the wiring kit, just a bit of wire to make power/ground long enough and some RCAs (/whatever input you're using).

It looks like the sub I bought is out of stock, but I would just throw it out there as - I wouldn't be afraid of an all in one, nor a relatively inexpensive one - this one was $120. I've been very happy with it, have no problems with it, and it's well more capable than I need (I think I have it running at <40% capacity - it's turned waaaaay down). My needs were similar - trying to make it sound better, but not competing in SPL or interested in making everything rattle.

Edit: Looks like there's similar models from other brands on amazon, I'd pick the one that looks like it'll fit + has reviews you're comfortable with. Alternatively, sonicelectronix has a similar planetaudio model (not sure what the difference is ...) for $99.

It definitely sounds like you need to add high-pass filtering on the feed to those tweeters - trying to run frequencies they can't produce through them would absolutely do what you're describing (it's exactly what crappy bluetooth/monitor/laptop speakers have issue with).

I'm not sure which Kenwood Exelon you've got, but most modern head units have some function for adjusting outputs to specific speakers. If it has an auto-setup, I'd even start with that - on my Pioneer headunit, it does a great job of setting up everything except the sub, which just then needs small adjustments (likely moreso preference adjustments than "correctness" adjustments).

Hey y'all, got a question. I'm trying to identify some superfluous connectors in a 2000 Mustang GT (w/ Mach 460).

This is one of those big things I didn't know I really cared about but I'm glad something tipped me off to - I got the Pioneer MVH-1400NEX particularly because I wanted a capacitive screen, and this makes me glad I did.

For the question side of things: If I want to switch on my camera based on the backup lights or a manual switch, how do I wire dual power? It seems like if I just run both wires in, it'll power on my backup lights when I flip the switch. Which ... I debated whether or not I even mind that, because it'd make it more obvious the camera is on, and probably light up whatever I'm looking at, but I'm curious how else it could be done - I know there's a way, I just have no idea what it is.

This is a basic integrated circuitry problem. What you're describing is an OR gate, in which the output is powered if any given input is powered. The inputs are dielectrically separated so they don't interefere with each other. This being said, I'm horrible at actual IC design so I can only show you the door.
Thank you! This actually ended up not being an issue (as in, I decided not to do it) because my thought was that I'd be able to turn it on without the reverse lights if I did so, and the camera actually has some pretty gnarly lights on it.

DrChu posted:

I tested mine out by tapping the camera power line to the 12V acc line going into the head unit. The head unit switches to the screen automatically based on the reverse trigger, and I should be able to start it anytime manually if I want using the on screen options. I guess this way the camera is always powered on if the car is, is there any reason that would be a bad thing?
The above is the only potential issue I see - I thought my camera had IR LEDs on it, turns out they're just really bright white LEDs, so it'd be pretty obnoxious to leave it on all the time. Other than that, it probably wouldn't matter. There's probably some argument of the device failing sooner because it's on all the time, but that's probably down to what quality camera you got and (more so) luck.

Mine was $21.99, sooooo ...

Oh! And while I wanted to be able to switch to the camera view and just look without putting the car in reverse, the real reason I wanted to be able to control the power separately was that I was worried about a delay when activating it. Total non-issue - it boots and sends an image instantly.

Why do fancy upgrade OEM systems always have weird speaker impedance? Bose is usually something really low like 2 ohms or whatever, and I've just discovered that our LS430's Mark Levinson sound system has a 16 ohm subwoofer. What's the deal? I've never had any normal speaker component that was somewhere in the 4 to 8 ohm range.
I have to assume it's either cost (probably) or exclusivity ("you have to use these parts, and only we sell them"), but I don't know. I do know that it blows rear end, because while I'm happy enough with how the Mach 460 audio in my car sounds, the connector sucks and a single speaker failure pretty much means replacing all of them at this point.

Question: If I'm getting alternator feedback (whine that matches engine RPM), am I better off adding a ground (I.e., keep the existing ground, but tee in another ground to a separate point) or replacing the ground entirely (ditch the one in the harness, just use one to bare metal behind the dash)?

I'm open to either but don't know what's more likely to fix it. The old head unit was using the harness ground and had no issue so I was hopeful it would work with this one as well, but no dice.

I'm of the opinion that the more the merrier when it comes to grounds, as long as it doesn't become messy or confusing. Try to tee in the new ground as close to the receiver as possible. I would leave the stock ground in place. Have you measured any voltage drops at the headunit? Do you have any amps or crossovers? Have you checked the body-battery and engine-body grounds as well?
To be honest, I'm not sure how to do this, but I do have a multimeter and I'm more than willing to learn.

The Mach 460 hardware in my 2000 Mustang GT does have external amps (x2), but no crossovers, as far as I know. The wiring for these amps have not changed beyond the plug that goes to the headunit (at which point, I've used a new adapter which goes to the RCA outs on my headunit).

I have not looked at the body-battery or engine-body grounds, but can definitely do so - is there anything specific I'm looking for, or basically just making sure that they're there and well-connected and substantial? (I.e., add some grounding straps)

Thank you both for your input - I was always under the impression that grounding of the headunit was to blame for this, so it's good to learn.
