I have heard that. When using an aftermarket HU low level is the way to go. However, when using stock HU I have to add an LOC which I've done before but don't like the fact that I will then have two places to set gain levels. One on the LOC and one on the amp. That just seems like a way to also introduce some noise. So, my options to use low level would be to keep my metra harness and add a 4 channel LOC or ditch the metra and get the PAC harness. Which ever I do, it will be another weekend or two of ripping everything out and fiddling around.
