Babyjuice Posted April 14, 2012 Report Share Posted April 14, 2012 My headunit only has 2 pre outs, and I already have a mono block hooked up to the rear/subwoofer rcas. Now. I want to hook up a 4 channel, would I be able to use the front rcas off the headunit then use the rca out from my mono block for the rear rcas on the 4 channel? Headunit: pioneer 3100dvd Mono: hifonics brz2100.1 4 channel: fosgate 300.4 BABYJUICE Link to comment Share on other sites More sharing options...

Jessica Posted April 14, 2012 Report Share Posted April 14, 2012 Just use a splitter on the rca's you run to the 4 channel. The Front RCA's, split it back by the amp. edit* if you run off the sub amp's rca output and you are using your head units LPF then you will only have lows going to your 4 channel on 2 channels Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

Kranny Posted April 14, 2012 Report Share Posted April 14, 2012 i just used the front preouts to go into the front input on my 4 channel. then used the amps pass thru and used like a foot long rca to connect pass thru to rear on the amp. works fine, you just lose front/rear fading obviously.

rocking.that.eclipse Posted April 14, 2012 Report Share Posted April 14, 2012 some 4 channels also have selectable 2 or 4 channel inputs. Maybe change up the 4 channel to one that is selectable Link to comment Share on other sites More sharing options...
Babyjuice Posted April 14, 2012 Author Report Share Posted April 14, 2012 So use the front rca output into the 4 channel input then us the 4 channel pass through and connect rcas from there to the rear input? BABYJUICE Link to comment Share on other sites More sharing options...
Kranny Posted April 14, 2012 Report Share Posted April 14, 2012 So use the front rca output into the 4 channel input then us the 4 channel pass through and connect rcas from there to the rear input? yes. or you can use the splitters like others have recommended. either will work exactly the same Link to comment Share on other sites More sharing options...

Babyjuice Posted May 2, 2012 Author Report Share Posted May 2, 2012 Ok so I got the amp and i'm ready to put it in but I can't get any rca splitters, so I was wondering if I can use the rca out from the Brutus amp and plug it into one of the rca in on the 4 channel? Im just confused sorry. BABYJUICE Link to comment Share on other sites More sharing options...
