I have:
(2) Kenwood KAC821http://www.scribd.com/doc/3275864/Ma...Manual-English
(1)-MTX tc4004http://www.mtx.com/caraudio/products...ers/TC4004.cfm

My speakers; front~ pioneer TS-C720 PRS rear~pioneer TS-D681R

I am building the sub enclosure found on this site to put under the rear seat~ 1.0 ft3 ~ I have not chosen the sub yet...

HOW should I wire this set up? 4 channel for front/rear then (2) 2 channel for the sub in parallel OR run each 2 channel for the front then rear and use the 4 channel bridged for the sub in series??

I wanna rock!!!!

 

can the kenwoods be linked?

i guess you could try it both ways, see which arrangement sounds better. cause as far as i know, there wouldnt be any real advantage either way (unless one of the amps has more features that you would want to use specifically on the speaks or subs)

 

I'm not really clear on the 3 amp thing. All you really need is two amps, a 4-channel to run the doors which looks like your MTX can handle fine and then depending on what subwoofer you choose a 2-channel or mono amp. If it's a DVC sub I recommend mono and if it's a single SVC sub I recommend a 2 channel. Crutchfield recommends the same and I have both setups, one in my 05 and the other in my 08. Knowing what sub would have and if you got 2 DVC then you would want a 3 amp setup.

Edit: I personally would recommend component speakers if your truck already has the cut-out for the tweeters, that MTX amp can handle most of the components out there and I can personally vouch for the Polk db5251 twice over.

 

Bridge the 4 channel to your front components, run a 2 channel on the rear speakers, and bridge the other 2 channel on the sub. Thats the best way to use all 3 amps.

 

Sounds great!!Thanks for the info
