DIY: Rear Door Speaker Wiring

[muggo05]

ok cool thanks. wasnt quite sure.

so what would you recommend me getting in my car then? 2 or 4 channel?

i will have 6inch in the doors front and rear.

will have 400W(200W each) 3 way 6inch in the front and probably (300W) 150W each speaker 3 ways in the rear.

depends, are you wanting a sub at a later date?

you are better off getting yourself a set of split componants for the front.

if you have the money and want to amp everything i would say go for the 4 channel. you will need to rewire all 4 speakers to the rear of the car however.

nah not to interested in a sub.

ok thanks for that mate. will look into what prices i can get

this is a great discussion. loving all this info. i've learnt so much in the last hour!

What about say, If I wanted audio input from two devices to come out of the speakers at the same time? Let me explain...

I've got a pretty standard Headset (Kenwood KDC-MP333) with two 6" ($100 Pioneer Splits) and two 6x9" in the parcel tray ($140 Pioneer Splits). I might think about a sub, but not for a couple of months.

I've also recently decided to build a CarPC (for GPS, MP3, OBDII monitoring and other stuff) and I want the audio prompts from the GPS to come out of the speakers at the same time as the radio/CD player.

I was thinking of running the Pre-Out from the headunit into the soundcard of the PC (i've got a good creative sound card - not the standard poo one) and then amplifying the signal from the laptop but if anyone has anymore ideas, i'm all ears.

[BlackVr6ix]

you could do that , but the only problem would be that you will loose your ability to safely control the volumes.

If you adjust the volume on the headunit it may/will overpower the input stage of the sound card. your options are really this

1) Do away with the headunit and run everything via CarPC.
2) Run a 2 channel mixer before the amplifier, that way you can independently control the volume of both units ie. set the upper limit of the carpc and the headunit on the mixer and then adjust each volume accordingly on the headunit volume control and your CarPC

[bboyskidz]

how much power does the pre-out connector usually produce at full volume? (as in Volts)

the latter idea seems like the best alternative - I'd like to keep the headunit as CarPC radios don't work too well...

thing is, the only ones i know of are the 240v DJ mixers...

[BlackVr6ix]

between 1 and 12 volts depending on the model. you can get passive mixers quite cheaply on ebay.

hey black. thanks for all the info.
Just 1 clarification. If I run a 2 channel amp I should stick purely for the 2 speakers and not add on a sub.

So on save side, if I eva do want a sub in future, I should get 4 channel amp right.

How about a 2-channel for the front splits, and a mono for a sub?
