HELP...... couldnt leave well enough alone/ STEREO.. LONG!

[PRE-H20]

Man o man... im going on info overload... getting a bit frustrated.

Going to leave work early and poke around some more....

1st thing going to check is 2 way vs 3way

Then onto tweeter connections.

1)- Check bal, fader settings all turned to zero. Turn off the xover all together- play it. See what happens.

2)- behind the face there is usually a spot to do a reset- pull face off, look for little spot t push with paperclip or other pointy object. Behind face, lower left.

3) If that doesn't work

- I would disconnect the speaker wires from radio should be fronts: (white and white with black trace and gray and gray with white trace) ensure there are no shorts, that will also kill output.

After you disconnect the radio, pop the speaker leads with a battery you cut going to MB Quart box- do the speakers pop? I would find it hard to believe BOTH sides would have a problem, but assuming you hear noise the wiring is OK going to the box.

If they pop, reconnect ONE set of positive and negatives speakers back up. It should play at that point. Reconnect the speakers from the radio to the wires and go.

Google how to reset the deck after overload. Something happened somewhere-you had blown fuses in the sub amp? So, most likely the Alpine has some sort of protective circuit that tripped, given that its amp output is dead. Gotta figure out how to reset this.

By default, out of the box you should get sound out of the front speakers and sub should go dead once reset.

Assuming it played before the battery swap this should make it work.

Randy.... I've already tried the reset button, didn't make a difference..... although I'm not sure if I did it correctly (I thought I did but it seems EVERYTHING is so technical, maybe I didn't do the reset correctly)

I know exactly where the reset button is.

How long do I keep the pin pushing the re-set button? just a quick push or for 2-3 seconds, or what?

Do I hit the reset while everything including the car is OFF?

Is the car set to accessory withe the stereo OFF?

Is the accessory on with the stereo ON?

[PRE-H20]

After checking 2 way or 3 way i will do a reset of the stereo.

After clarification on the RESET protocol.... then I will go through this series:

1)- Check bal, fader settings all turned to zero. Turn off the xover all together- play it. See what happens.

2)- behind the face there is usually a spot to do a reset- pull face off, look for little spot t push with paperclip or other pointy object. Behind face, lower left.

Manual on resetting says:

"Initial System Start-Up
Be sure to press the RESET switch when using the unit for the first
time, after changing the car battery"

1. Turn off the unit power.
2. Press RESET with a ball-point pen or similar
pointed object

BUT it doesn't say anything about the car being on or in accessory mode.

Does the car have to be completely OFF?
Does the accessory have to be on BUT the head unit off?

stay focused on this. everything worked before changing the car battery.....so that means you connected everything correctly

i was going to suggest you attempt to bi-pass the crossover to rule out a faulty crossover component but not sure how changing a car battery could suddenly kill BOTH crossovers in both doors

also. i assume you’ve either changed or disconnected and reconnected the battery at some point in this stereos lifetime without issue many times???

this is indeed a mystery BUT the fact that this issue is in both doors probably tells us something and my guess would be there is a fatal issue in the head units amplifier section. i don’t think it should make a difference but was the stereo turned on when you reconnected the battery?


i would think the preamp section is ok since your sub is getting a signal

[ramonesfreak]

i can see why you would ask this. very confusing. if unit power needs to be off then what’s the difference if car is on or not on. at this point i would try it either way

So I am nooooo expert but this doesnt look good and I probably found the problem!

Came home and jumped in under the car.

I went to go check to see if the HU was set to a 2 way or a 3way.....

This is what I saw..................................






Confirmation that its fried anyone ?

I'm pretty sure it is NOT supposed to look that way.... a nice white button like the other side should be there right?

[PRE-H20]

I also just hit the RESET button, just in case......

The deck did in fact reset, all the preset stations are no longer preset.

I had the accessory to the car ON but the power to the unit OFF as described in the manual. It shut off and reset.

Turned the unit on, BUT as expected power to the front speakers was not there.

I'm pretty this unit is toast, just waiting for Randy to confirm........................... dammit.

[ramonesfreak]

i looked up the manual and on page 7 about startup procedure and would agree that the reset button is the obvious thing to do and should fix the issue

why you hear nothing still, i don’t know.

[RANDY P]

Those switches look normal, and the unit worked prior to pulling the battery. They all look like that.

Get a little battery out, cut the wires coming out of the radio to either pair of speakers (either the white or Grey) and pop them. If they pop, it's nothing with the speakers.

Give it a shot.

A few seconds while car is in accsy should be fine.

PS pop the speakers to confirm they are connected still. If they are, test for speaker output from the OTHER pair of speaker wires that are supposed to be for rear speakers- violet / violet black the other one (can't remejmber of the top of my head)

If the front speaker connections are dust maybe the rears are OK...

[ramonesfreak]

if it makes you feel any better, i recently replaced my old alpine 9883 with an Alpine CDE-172BT that costs only $130 and i much prefer it. my only issue with the new ones is if you have a power antenna, you’ll need to install an in-line on/off switch so that your antenna isn’t always up even when your not listening to the radio (tuner) -STUPID !!! they are all designed this way now and i hate it

if you want my old 9883 (if i still have it) i could mail it out to you this weekend. no wiring harness (i reused it on my new one and i think I lost the one that came with new unit) some of the writing has rubbed off and it could use some plastic polish, otherwise it worked fine. if you want it, PM your address and it’s yours

[PRE-H20]

I'm blown away......

Randy the pictures of the crossover 2way/ 3way that is all black and shiny is normal looking?

The other button with the EQ/DIV is also normal?

Sorry to be such a newbie but I just don't know... please confirm.

I will check the wires too........

Correct, they all look like that- broken. They're fine tho.

You got another cheap speaker laying around to plug directly into the radio? Test the speaker outputs that way.


PS if that deck has dead outputs, all is not lost.

If it were me: I would BUY a decent 4 ch amp with a built in xover, and remove the existing amp, and plug that in instead. Reconnect the RCA's from sub out in deck, to either front or rear, then disable the internal xover on the radio. Plug the new amp outputs into where the existing deck is wired to and forego deck power to run the front speakers.

Use the xover in the new amp instead. Would likely cost you less going this way plus sound much better and you can save the radio.

EDIT: try the rear outputs on the radio, hope they work. If they do, use those. safe diff.

[PRE-H20]

Randy thanks for the insight and IF this deck is toast.... i will absolutely go that way for sure. i like that idea.

also.... based on the picture i posted...... can you tell if the cross over is set to 2 way or 3 way? i have no idea what i should be looking for or at.

[RANDY P]

Not sure, but I use a small flathead to just make sure it's there. It's just a very cheap and ugly switch.

If you decide to do a 4 CH amp, just about any will do if it has a built in xover, not big money to obtain-do check to see if you get any sound output out of the other RCA's by plugging those into the sub amp first to ensure the deck has output there. If the sub plays mids and highs, you're golden.

Won't hurt the sub, they don't care

[PRE-H20]

man o man... i would love to do all this that you are suggesting.... i just simply dont know how.... im in WAAYYY over my head..... i went down a rabbit hole that i shouldnt have gone down.

Randy, can shoot me an example of the Amp your referring to? a screen shot would be great...... i just need a starting point.....
