I just recently put a 230 amp on my 4.3 blazer. It works great i run a saz3000d and a memphis 300/4 i have a optima yellow top up front and 2 deka marine batteries in the back. Full tilt it stays at 13.0 volts with no problems. Tejcurrent is a good guy and stands behind all his products so you will have great customer service. Thanks tejcurrent
Not to butt in or anything but i have a old style as well with a broke tinsel that i know i can fix. But i just need some tinsel does any one have any????
