OK...I have everything run for my brother's install. The amp turns on, but the subs will not hit. Where should I go from here? I have a high output converter because he has a stock deck if that helps.
Thinking out loud...so, if I have power to the amp, that means my power, ground, and remote turn-on are all good, and it must be the RCAs not getting signal to the amp???????
if he has the Line output converter for his RCA's then check the gain on that. On LOC's they have gain's just like amps,one for the right channel and one for the left. set both of them the same and turn them up to see if the subs will work
