Understanding the System

Hey guys... I'm looking to redo the system in my F-150 and have some basic audio questions. I recently purchased a Pioneer 6000 CD headunit. It has a 5v pre-out labeled "front", and a 5v pre-out labeled "sub". So I wanted to dedicate one amp to run subs.... so I run that off of the sub preout. And then I wanted to either use 2 2-channel amps for the remaining four speakers, or 1 4 channel amp. But, the preout is only labeled "front". Does that mean that the signal from these pre-outs is only for the front speakers, and I have to leave my rear speakers un-amped? Or are they figuring that once the stereo is relieved from driving the front two speakers, that it will be able to pump 90 watts to each rear speaker? Thanks for your help guys.

Understanding the System

Looking at the little info on this unit in Crutchfield,the 2 sets of rca's will be fadeable front & rear.If you would've got the 7000 w/3 sets of rca's,the subwoofer output would not be affected by the fader.Of coarse,the amp's you choose will be the deciding factor of what runs the front,rear or sub.Before you go further,do you have the owners manual for this radio & have you read it ? Some radios can power speakers and pre amps at the same time,some only front & both pre amps, etc.If you can't power speakers & pre amps together,use a 2 way amp w/sub crossover & high pass output on the radios rear pre amp,but run the rear pre amp full range(if possible,check manual!),the amp will crossover the subs for you.The amp will also power your rear full range speakers on the high pass side.For the front preamp,a simple amp of your choice will power your front speakers.There are several alternatives to this configuration,but only once you know if you can run speaker(s)out & pre amp out at the same time,or a variation of it. Oh,by the way, a bandpass box is the way to go for your subs,if you can give up the space!

There are a few ways of going about this ,but, the best and the safest way would be to invest in an eq. Some have a single input and three sets of preouts (front,rear,sub).What this should also give you is a subwoofer level control and possibly even an adjustable crossover for a little more flexability. Most fixed xovers are set at 80 hz. An eq would also clean up your sound and improve the overall sound quality.
Anything else just ask.

you're right dude, i didn't think about it cause he never mentioned an E.Q.with the right eq hooked to the front pre-out,he can have to sets of subs running plus 4 full range speakers,if he can cram it all in. i always wanted to have a dual band pass box for super lows as well as a dual sealed box for the upper lows.maybe one of these days!

I would suggest using a Pioneer DEQ9200. It has 3 RCA outs, DSP, cool dancing lights (chicks dig it), and more features than you can shake a stick at. I have it in my 77 F250. The system I have follows: Kenwood KDC3006 ( 10 disc changer), DEQ 9200, Rockford Power 300 (150wx4), Rockford 6.5 in the doors, Polk tweets, 2 Kicker Comp 15's (yes 15's) befind the seat.

I run an Alpine ERA-G320 sound field processor.It has time delay, 6 surround modes, BBE, 6 eq modes, adjustable eq, 7 band eq/surround or 14 band eq or 7 band front/7 band rear, sub control, remote controlled with certain Alpine Ai-Net decks, 4 volt capable,8 different display options. Real nice EQ but it is fairly expensive.Well worth the money if sound quality and control is what you want though.
