I have a vw polo 06. Can i hook up a sub plus rear speakers to the factory fitted cd player?

Hi.if the speakers is to big for the Radio it wil frey the internal amplifier of the radio

you must have a car with a factory amplifier? if so, both your sub amp and the factory amp have to be hooked to the blu/wht amp turn on wire.

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.

the car should have a molding frame around the air vents, that also goes around the radio, but may be sepret too, should just pop off with a screw driver or pannel remove tool

VW only activate the fader if rear speakers are fitted, go back to the main agents and check if speakers should be fitted or not.

the conetion wiers are brokem you just have to change them.

bose speakers are EXTREAMLY sensitive to the current applied to them. meaning if the wrong amount or too much is applied they will not work or will blow out completely.. was the other cdplayer stock? if so id go to radio shack and get a cheap speaker and hook it up just to see if that would work

no sound going to the speakers

What kind of car did you install this in? Did it have a factory radio in it? If I had to take a guess I would think that there is a factory amp that you may have hooked the blue wire from the alpine deck to. If this is the case when you switch to CD the alpine deck turns off the power to the power antenna lead(blue wire) and thus your factory amp. If this is the case hook the factory amp turn on to the blue and white wire and you should be good to go.

if it is only doing it over 30 then you need to turn down the bass level on the deck and make up for it with the subs sounds like its putting out too much juice. also if your car has a factory amp for your door speakers ect make sure that your factory speakers are the same ohms as the cd player which is 4ohm ,most fancier car speakers are 2 ohm. if that is the case the amp on the cd player is going in to protect mode to prevent frying your factory amp if you have one. check all your wiring from the cd player to the car and make sure it is all properly hooked up and there are no crosed wires. or wire hooked up incorrectly. also make sure the amp wiring kit is big enough gauge for the amp. make sure its not the amp that runs your subs that is cutting off the HU.
