I have an alpine mrv-f400s 4ch amp and want to bridge to 2ch. I don't know how to place the channel switches to properly bridge for 2subs. It has 2 switches for 1/2 channel side(input mode and filter) and 3 switches for 3/4channel side(input mode,filter and input channel). The input mode for 1/2 says (1. St. 1+2) and3/4 says (3. St. 3+4). And input channel says(1/2. 3/4. 1+3/2+4). My question is=how to switch all 3 switches to run 2 subs? I know the filter switch sets to lp for lowpass but the others have me stumped. Can anyone help? Please. The mrv-f300s is the same way if that helps too.

easiest way is to set the input mode switches to 1 & 3. plug your left RCA channel into RCA input 1, plug your left RCA into RCA channel 3. then bridge each sub.

Understand that but what about the input channel switch? Should that be on. 1/2. 3/4 or 1+3/2+4
