Car deck turned too loud and shut off

The deck might be damaged. In order to accommodate that kind of layout, there should be a cross over, and a separate 2 channel amplifier for the subs. Without that it's easy to fry the deck!

Hi! Try not to install the amplifier first. Proceed on standard wiring set up without the amplifier for you to trace if the amplifier is faulty which can cause the other speakers not to work. Hope this helps and thank you for using FixYa!

How can i test my rca output jacks with a test light? pioneer deh p3100ub. hooked up spkr, nothing. tried one rca plug to white(lt) and then red(rt). Unit has 4 rca jacks, 2 for subwfr and 2 for front...

:) the rca jacks have to be connected to an amplifier,, their signal is too lay to even light a bulb.. you have to connect it to a car amplifier and then from the amplifier to the speakers..

Just so you'd know,, once your deck plays and you hear music on your speakers through your normal speaker wires,, RCA jacks work..

Ok you have 4 jacks,, 2 subs and 2 front.. These should connect to a preamp,, which takes 4 inputs and allows you to equalize or adjust how the music should sound,, now from the pre-amp,, it runs to an amplifier,, thats powers the subs and another that powers the speakers.. Some amps have 4 inputs so you can use one amp for your subs mids and heights..

for example a basic music system is

1 cd player
1 pre amp
1 amplifier (4 inputs, 4 channel out)

you bridge 1+2 and connect this to 1 12" double coil sub woofer

the next 2 connect to 2 mid speakers example "rockford or ev 5 / 8 " and 2 tweeters for heights..

Thats a kicking tricked out basic car audio system,,,

Hope that helps you understand how it works..

I am trying to install my xtant 604x after i just had it sent out and repaired. I have 4 rca's coming from the head unit wired to the amp as FL, FR,RR,RL. The front speakers connected to the front output...

As we agreed in chat - you are going to run your 4 channel amplifier as follows...

Front Channels of amplifier will run left and right independently.
Wire up the left speakers in parallel all + together and all - together.
This will yield a 2 Ohm load.

To the Same with the Right Side speakers - on the FRONT Right channel of the amplifier.

Now you have a 2ohm stereo load on the FRONT channels of your amplifier.

And using the BRIDGED nomenclature on the REAR channels of your amplifier - wire up your 4ohm sub mono.

Here is a crude drawing for a visual


Thanks for using FixYa - a 4 THUMB rating is appreciated.

Volume fade

Check to be sure there are no speaker wires touching ground, and that the wires are connected in phase to the head unit.
Front Speakers 5 1/4" Doors Left Front (+) Green Left Front (-) Black/White Right Front (+) White/Red Right Front (-) Black/White Rear Speakers 6" x 9" Rear Deck Left Rear (+) Pink/Red Left Rear (-) Pink/Blue Right Rear (+) Pink/Light Blue Right Rear (-) Green/Red

The symptoms you are relaying definately sound like an internal amplifier problem. It is fading in and out for a reason - usually due to heat.

Have you had the radio bench tested (seperate from the car) to eliminate the car as being the culprit?

Since the radio was run with damaged speakers originally, the output or amplifier power supply on the amplifier may be bad.

As an alternative to repairing, I would suggest investing in a small 2 channel amplifier to power the speakers.

The radios claim 50W per channel, but in reality give 12-15W RMS power.

A dedicated amplifier with built in crossovers and gain adjustments will prolong the life of your speakers and add to the tonal qualities of your new speakers. Instead of turning up the volume on the head Unit, and sending out a distorted signal that will blow your speakers, an amplifier will give more CLEAN power to them, so it will be louder at a lower volume setting.

This will bypass the internal amplifier on the radio, and send a Low Level signal ONLY thru a set of RCA cables.

Good Luck!!

CDA 9885 No idea why it suddenly stopped working

It sounds like you have a bad ground connection. You need to take the radio out and check all the connections. I bet you have a loose one somewhere. That is what the problem was with my bronco

Sony cdex-m630 connections with an amp

You can use either set of RCA outputs for the amplifier that you want to. Only difference in either of them is front, rear and sub outputs. If you are only powering a sub amp, then use the sub outputs, otherwise, the other two will work fine. You can still use the outputs from the radio itself to power four other speakers while using the RCA outputs.
