I just installed my amp(v12 alpine 600w rms)/sub(10" alpine type R) to my deck (alpine 9856) it doesn't feel like i'm getting the same power out of it as i used to in my old car (honda civic),,,it is currently in a '01 tacoma is there some settings on the 9856 that can adjust the sound? i've messed with the subwoofer settings some but, not real sure about the deck yet. any help would be appreciated...
