Switching from fronts & rears to front comps only. Need hookup advice!

[kruser0922]

Hello all. I am new to this forum but not a total stranger to car audio.

I am finally ready to make the switch to front comps only in my 1990 Corvette coupe.

I am currently running Polk MM5251 comps in front and Polk MM691 in the rear powered by an Alpine KTP-445 power pack connected to an Alpine CDA-105.

I am switching to Polk MM6501 front comps powered by a JL Audio XD400/4 (already have the amp).

What is the best way for me to connect these comps with the 4 channel amp to maximize safe power usage for SQ without worrying about burning up the speakers? I should note that I will be installing 1 JL Audio 10W6v2 mated to a JL Audio XD600/1. Also note that although I would like to crank it once and a while, I am mostly interested in SQ.

1. Run front amp channels only to the passive crossovers and leave rear channels empty?

2. Bridge the channels and run through the passive crossovers?

3. Power tweeters with front channels through the passive crossovers and power woofers directly hooked up to the rear channels and use the amp crossover to cut rear signals?

Pros & cons to each option above?

Specs on the JL Audio XD400/4:

Continuous RMS power @ 12V

@ 4 Ω 60 W RMS x 4

@ 2 Ω 90 W RMS x 4

Bridged @ 4Ω 180 W RMS x 2

Thank you in advance for your advice!

I would suggest running the tweets off front and mids off rear but it looks like that amp doesnt have a high enough filter option to cut out the crossovers to the tweets. And since you already have the amp I might suggest looking into a set of components that have a bi amp crossover.

Any suggestions for components that are bi-ampable that won't break the bank and still sound decent? Thanks.

Or could I run the front channels for the tweets through the passive crossover that came with the MM6501 set and run the mids directly off the rear channel?
