my HU has got dual preouts (front/rear or front/subs). I'm thinking of hooking up the front and rear channels to an amp, and have a separate amp for a sub, so i want to keep the sub rca-outs free and the only way I can get my rear speakers to RCA level is by using a LOC. is there anyway i could avoid having to do this? As i've heard that LOCs may cause your SQ to decrease. If theres a way to minimalize this as much as possible, how do i go forth about it?
Thanks
Run your pre-outs to a four-channel amp with the head set to front/rear. If your main amp has RCA outputs, connect your sub amp to these. If it does not, simply use a Y-cable to split the line-level signal for the rear channel to connect to the sub amp. Use the LP filter on the sub amp (or an external crossover.)

Support the12volt.comwell.. the thing is that the rear or sub pre-outs can only be used for either one as you can set it on the headunit if you want it as sub woofer output or not and i'm afraid if i connect the sub and the rear 6x9 on the same channel, it might drain the treble on the 6x9.
p/s i'm here on my computer and at the same time crimping the terminals on my wiring harness, was wondering if theres a difference between Illumination & Dimmer. Do they go thru the same +12V each time the lights are on? or are they the opposite of each other?
It shouldn't drain the treble from your 6x9s as long as you have the rear channels set on rear instead of sub. Then you could split this signal and use the sub amp's built in low-pass crossover.
