Up for sale is a Kicker ZXSUM8 signal processor. This was in my car for about 3 months, but I no longer need it since I upgraded the head unit. It's in excellent condition. Included is the unit, Subwoofer/aux control, and the wiring to connect the two. This was $200+ tax when I bought it, so the price is firm. If you have any questions, or you're interested, give me a call/text at (832)339-6482.
