Yeah, you don't have to have RCA's to use the MS8. It comes with hi level input plug. You find out the color codes of your head unit speaker wires and hook up to them. For instance, if your front right is red and red and black, the plug will be labeled for front right. you just hook up the positive and neg and it gets its signal from that. The MS8 does its processing and creates a low level (RCA) output to send to your amps. It designed to be able to get a great system keeping your stock headunit. There is a thread over on DIYMA that is really long that goes into crazy detail all about the MS8. It tells you how to hook it up, tune it, tricks and tips, etc. Really useful thread.FS: Stock BRZ head unit (Sat, Nav, BT audio, etc) with amp & speakers - Scion FR-S Forum | Subaru BRZ Forum | Toyota 86 GT 86 Forum | AS1 Forum - FT86CLUB has pics of the back of it. There isnt any rca outputs. Would i still be able to hook an amp up to it?
Thats awesome man. Did you buy the one from him or a new one from vertex? That with that MS8 and some HSK's are going to sound great. Some people don't like Hertz too much but they are my favorite brandOk i just bought that zed amp. Its to good of an amp to pass up
