First of all, I have a factory GM CD player. I have no intention of replacing it anytime soon. Since the factory HU does not have rca preouts, I have converted speaker wires to rca with (2) PAC 10 to 1 converters. Now that I am converting over to JBL amps, which have speaker level inputs (I have never had an amp with them before), I am considering eliminating the converters and hooking the amps up directly with speaker wires. Since I will not run anything off the HU, I thought I could get a "hotter" signal to the amps this way. As weak as the factory HU is, I think the 10 to 1 reduction is too much. Also, by eliminating the converters, and rca cables, would I lower signal loss? Any help will be appreciated.
