Matt9ball Posted September 19, 2018 Report Share Posted September 19, 2018 Hi all. Hope someone can advise me. I have a 4 channel amp and a head unit with a pair of rca outs for front and a pair for rear. Also a sub out. Would like to connect 2 front speakers (6in 3 way) and 2 rear speakers (4in 3 way) as well as a 12in sub all to a 4 channel amp. I would assume it's best to bridge the channel 3 and 4 on the amp to the sub but not sure how to connect the hu to the amp. Link to comment Share on other sites More sharing options...
bcbrassard Posted September 19, 2018 Report Share Posted September 19, 2018 Welcome.... Front speakers to ch 1 &2 of amp. Rear speakers to rear output high signal from HU. Sub bridged to ch 3 & 4. You really don't need rear speakers amplified, especially that small of speakers. This set will give you balance control, make your front stage sound the best and have a sub. A 5 channel amp would solve all your issues though. Good luck. Link to comment Share on other sites More sharing options...

PaCiFiKbAllA Posted September 19, 2018 Report Share Posted September 19, 2018 The sub out is only if your running a seperate sub amp, in which case your not. Set the head unit to flat and use the HPF on the amp, at least that’s what I would do. As mentioned above, bridge the sub to channel 3 and 4. What deck and amp are u using? 1 x Fi Audio SP4 V2 12" D2 Fully Loaded 1 x Wolfram W-4500.1 2 x XS Power D5100's 250A Singer Alternator 2.67 Cubes @ 29hz Link to comment Share on other sites More sharing options...

Regards the bridging sub to 3 and 4, should i run the rear rcas from the hu to the amp to the inputs of channels 3 and 4? Link to comment Share on other sites More sharing options...
