my friend is wanting to keep his stock HU in his 04 chevy crew cab. He wants to put a line out converter to power a kx600.1 for 2 10" w3's and a lunar 40x2 to power his mids and highs.
The guy at the local audio shop said that he doesn recommend hooking up the mids n high amp to a line out converter bc of high freq. or some bs. This guy has done setups like this before and said that the mids n highs get louder but they dont sound clear.
Is there anything he can do to get the mids n highs to sound clear without buying a aftermarket HU? Would low/high pass filters do anything?
