Focus Speaker, Amp, Sub Installation
I have a 2004 focus which i want to upgrade the stereo. Theres a few things i know, which have made me come to a decision as to what im going to do. The factory unit is a double din size which will make it a bitch to put an aftermarket unit and i want to keep the steering column controls which has made me come to the decison that im going keep the stock head unit and upgrade it.
I have a kicker kx350.4 amp and a kicker 12inch comp sub which i had from my previous car and want to know how to wire it up. This amp has high level inputs which means i dont need to buy line out converters for RCA pre-outs. I want to upgrade the front speakers to some new 5*7s which i still have to look for and have these running off the amp as well. Now for the wiring, running the front speakers off the amp is a breeze coz i will just have to run the speaker wires to the amp and run the amplified signal to the new speakers, but for the sub is what i dont know. My other head unit had some sub-out RCA's which made adding a sub easy, but now i dont have this sub-out connection. Im guessing id run all for of the rear speaker wires to the amp and use a bridged connection to run the sub and make sure the lo-pass filter is on, but i also want the rear speakers to run as well. So how would i go about this? The way ive heard is to split each of the rear speaker wires and run a half of each wire to the amp and the other half of each wire to the speakers, but this would mean that they are running in parallel, and by the tech book of my last head unit, it emphasised the point not to run speakers in parallel. So this is the part that has me stumped. Would i need to buy any special gadget which would allow me to run the rear speakers and sub in parallel or should i just ignore what the tech manual from my last unit said?
Also, any one know what colour wires are for what in the 2004 focus, in particular speakers, acc power, const power, and a wire i can use for the switching on and off of the amp (remote wire?).
