Hey guys, Just quick question, the alpine cda 9831 has 2 rca ouput and another line with a subwoofer rca output? when i plug in 2 rca's into the normal rca outputs and a rca cable from my sub to the subwoofer rca output, the subs dont go off? but if i plug them in the normal rca output, they do? do i need to adjust something? or set up a setting? or should i just end up buying one of those rca splitters? much appreciated

why would u bee running a rca cable from your sub to the subwoofer output, im guessing you said that wrong, but you mean you run the subwoofer rca output from your head unit to the amp thats powering the subwoofer? correct. you must have something wrong with your headunit, the subs should be working perfectly fine with what you did

it wasnt turned on in the head unit, when i went to setup, it just had adjust clock so thats all i thought, ended up being under SETUP, there was a option to turn 'SUBW' ON.
