Only door speakers have sound on the cd mode

prob a bad radio, but try checking your wires

So you wanna run the subs off of the rear pre amp output rather than just the sub out correct? just get a splitter and run both the rear speakers and sub off of rear channel and front off of front channel. or run all four off of front and subs off rear output. this should give you the sound you want

:) 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..

depending on how many channels the amp is, you may not be able to hook everything up to it.

usually you have a separate amp for subs. 4 channel amp for the speakers in the car, and a mono amp for the subs.

To hook them all up to the same amp you would need an amp with 5 channels. It wouldn't work out right.

If you have a mono amp its only for subs.

If you have a 2 channel you can either hook it up to the rear speakers or bridge them to mono to run the subs.


you need a channel per speaker basically.

if you have both amps connected to the same power wire this will happen...run another power wire to the alpine and this should solve the problem.

you are not getting your amp enough volts try checking your ground or power cable

YES!! You used the blue wire to turn on factory amp (blue wire to GM pink) you NEED to use the Blue/White wire. That is the amp turn on. The blue wire goes dead when you play a CD or DVD because it's for a power antenna. So, Blue/White ok?

Run your 12" subs off the amp make sure to Xover for bass only.
Try running the 4 speakers direct to the stereo may not be enough power, Might have to invest in another amp and speaker upgrade to get it sounding just right.
But its a place to start.

1st make sure your amp is coming on. Use another speaker that you have heard play to test it.
Next test the woofer with a 9 to 15 volt battery. Touch the battery leads quickly across the + and - on one side at a time. The speaker should move and make a pop on both voice coils.
If the amp plays and speakers play, then you need to know the power rating and impedence stability of both amp and speakers. That will determine how they are wired up.

Select different modes on the remote or front panel and make sure all speaker that you have hooked up are showing on display. Are the Lt & Rt channels at least playing audio?
