i hooked up a alpine swr-1222d to a alpine mrp-m1000. i havent tuned it yet, and it kind of sounds terrible. just wayy tooo much bass.

i was thinking of getting a alpine pxe-h660, or some other sort of factory integration device.

has anybody used any of these, and can i get a harness kit to hook my navi h/u into the processor, then hook the factory amp to the processor? thanks guys
