I had an aftermarket in mine when i first went aftermarket - output was terrible, i literally couldnt hear some songs because i was using the RCA outs and the wire harness i was using had RCA adapters to go to the amp. It turned out the factory radio uses regular speaker output that goes to the amp, and the amp takes the huge signal and just splits up the frequencies and might boost em just a tad. So if your aftermarket radio doesnt have very high rms wattage, that could be part of the issue. if you are using RCA instead of speaker outputs to go to the amp, thats the other issue. its all in the wire harness.
