[QUOTE="2loud4u, post: 2117824, member: 562346"] Ok do this First have a dmm and some test tones Set your gains by the following. With your car off Disconect your speaker wire from the nine.1 Hook up the dmm to the speaker terminals Set lpf to 80hz Turn system on. Turn off your eq Turn the sub control all the way up Set your bass boost on the deck to what ever you want Pop in your test tone 0db, -3db what ever you pick at around 50hz Turn head unit up 3/4 the way Now go look at the dmm and keep turning up the gain till it reads 34.64 on the dmm Once you reach your voltage leave it there and shut off the system Rehook up your subs to the amp and test it out. If you are still not happy with the output I suggest you build a ported box. That is if you have your subs wired down to 1ohms. [/QUOTE]
