My question is about rcas. My sub amp does not have rca outputs, only input. I have my new speakers and a rf power 400.4. My sub amp is an mmats. But neither have outputs. Should I just use a y split on my current rcas I have running into the trunk? Or can I run two rcas. Any advice or help would be greatly appreciated.

You didn't mention what head unit you have. If your head unit only has one set of RCA outputs and your amplifiers have internal crossovers (or if you're using passive crossovers), using RCA Y adapters will work fine. If you head unit has an internal crossover, a dedicated sub "RCA" output, and front and rear "RCA" outputs, I'd run additional RCA's to your amplifer(s) as needed.

Still have stock head unit with loc. So my best bet is probably buy head unit with more outputs and run a new rca. Thanks man that clears this up for me. Although head unit isn't in the budget right now. Is running a splitter okay one amp is mono block, the other is 4 channel. I guess I'll just make sure my crossover and hi/lo pass filters are set right.
