Is anyone besides Kirk using Zapco's DSP6-SL but with non-zapco amp/amps and the oem deck? I am currently using Zapco's din to RCA cables (no LOCs) and have gotten less of the dreaded hiss than I did with Navone's LOCs. However there is still some hiss/noise floor problems. I know many of you really like the Rockford Fosgate 360 but I would prefer to maintain my steering wheel controls.

I am not sure if the DSP6-SL will help with this problem or not using non-zapco amps. I emailed zapco but received a short, non helpful response. Zapco's signal processor happens to be quite a bit more expensive than the RF 360 but if it works I would gladly pay the money.

Thanks.
