[QUOTE="Darwin, post: 406437, member: 544843"] I have a new (refurbished) Pioneer DEH-P6500 (yay). It has a hell of a lot more options than my old Aiwa CDC-X217, and I'm trying to figure out the best settings to get good front/back sound from my Kappas while retaining a good thump from my JL 10s. I will organize my thoughts into questions for convenience. ;D 1. The head unit has 3 RCA outputs, one is marked front and the other two are marked rear "subwoofer/nonfading" (whatever that means). The rear ones are on opposite sides of the back of the head unit, one of them is built in and the other is a cord leading to two RCA outs. The instructions are very dim as to what they all do, so I picked one of the rear ones and plugged my sub amp leads to them. Works fine, but I'd like some confirmation that these are in fact identical. If not, how are they different? 2. The head unit has a subwoofer output and crossover adjustment if you set the preouts to "S/W" but if you set them to "FULL" you only get a bass/treble control. My amp has a crossover of its own of course. How do I deal with this? Obviously I don't want to be sending extra frequencies to my sub amp, but the head unit only goes up to 125Hz (though you can adjust the "output power" +6/-6). In the past I have usually kept my sub amp at 160+ to retain good thump. How do I set this up? 3. The output is 2.2V.
