hmsracing,
When you yanked the headunit out to work on upgrades, was there any kind of low level rca sub output on the back of it?
I know you can run line level converters or use spkr level inputs if the additional amp supports it.. but it'd be easier just to run rca cords if they're already there.
What did you finally end up doing to your system? Did you ever pull the trigger on that JBL processor? That looks interesting, but for the $$ I wish it packed a little more wattage.
I know more than anything the 9 spkr system will lack bass, which is why I will add a woofer first. JL makes a nice amp with a subwoofer adjustment knob to fine tune the sound. I figured I'd crank down the bass on the headunit to limit low freq. distortion on the factory spkrs, and dial it in on the dedicated sub amp. ( I had similar setup in an old Pathfinder my son now has. ) I'll see how that sounds first, then see if I need to dive into another amp and front spkrs. I really can't see spending money on the other speakers in the vehicle due to their placement. They should suffice for rear fill ambiance.
