i just had to try that picture out hahah. you should sell that amp and buy a monoblock i have no experience with 4 channels sorry
The amp is just temporary it came with the subs and that's what the guy was using to power them. If I can get the subs to sound good, I will be purchasing the correct amp for this setup and use the 4 channel for the door speakers. I just wanted to make sure I am wiring it correctly.
