SOURCE: Alpine mrp-350 amp
1) If you bridge on a non bridged amp your sound will be horrible as they sine waves comming out of the two teminals will be different... I suggest removing the bridge. 2) The gain knob is to adjust when the amp will reach its max volume with respect to the sterio;s volume. 3) the LP filter is a Low Pass filter and its purpose is to eliminate the higher frequencies that do not sound all the well when played over subwoofers.

is the remote lead properly connected to the head unit? if the power led is on then the power cable and earth must be good, check the remote lead 2 your head unit first, if thats all good try looking at the amp to see whether theres a small switch to adjust the output going to the subs, if its very low or right off then nothing will be going through to the subs. if its on high and fine it only realy leaves the neg and pos inputs from the amp 2 the subs.

I'm assuming this atleast a 2 channel amplifier all you need to do is hook the negative side of the speaker wire coming from the sub to the negative channel one. and the positive to another positive on channel 2. Should indicate on your amplifier channel one and two. most amps provide a diagram right on the amplifier over top of the speaker inputs. let me know if this helps.

Sounds to me like it might be the remote turn on because the first time i installed it, it did the same thing, and i found out that there is two blue wires coming out the stereo, one with a white stripe, i connected it to the blue wire, and it didnt work, then i connected it to the blue and white wire, and it worked. Well hope this solves your problem, goodluck.
