Thank you ! I also think I'm going to run the loc rather than the speaker level input . With the speaker level input I can't turn anything up at all on the amp without it clipping . Any advice on that ?Altima17

yeah with the loc it will have adjustment so the amp isn't being over driven. If doing high level inputs the amp is talking the decks power (usually 17 watts) and amplifying that. With the the loc you can turn down the input to better match the amps input (2-6 volts common). So your not amplifying a amplified/distorted signal. I never use high level inputs except on alpine power pack33 years as a installer now just a retired old guy. Favorite thing to install/topic are remote starts/car alarms. Stop using test lights!!!
