kicker is a kx600.1 a few years old but puts out just like new..the rockford is a bd1000.1 also plays like brand new, only had this one in the car seriously for one day, a bass off, after that took it out and been sitting in my closet since..i can power everything upa prove it all works like new!..pioneer flip out and the dvd/cd player for it i will let go for 125..not asking much for it cus it is older and not touch screen, again works just fine, and parking brake input is bypassable by grounding the parking brake line to the unit.. kenwood 519 and kenwood 5019 radios with front and rear outputs 60-80 bucks got a couple of these,and a kenwood x719 excelon radio with front rear and sub outputs for 125, all black flip face radio..good radios for a great price...
