its the factory amp into line output convertor. Factory amps always mess up the signal with their built in EQ curves and crossovers. You arent getting a flat signal. The orion amp handles clipping better than taramps which is why you think it performs better. Taramps should perform way better with a proper full range flat signal.
read through this thread. same issue as yours pretty much and pretty much how he solved it and the results.
Hello, I just bought a Taramps MD.1800 2 ohm amp brand new from the manufacturer for my two 12" Rockford Fosgate P2 dual ohm subs. I hooked it up with my new KnuKonceptz Klarity 2 channel RCA's and re-did the ground due to previous amp issues and I'm not getting any sound from my subs at all...
