most amps have speaker level in. you dont need an RCA converter. you can splice into the rear speaker wires in the trunk (so u dont have to run them to the hu). if the sub has "auto sense turn on" you dont even need to run a turn on lead from the hu. the amp should have a "low pass filter". you dont want those high sounds going to the sub.
