Hello everybody, I just had a quick question. I have a Koiiler xm-8686 4 ch amp, I am running two subs bridged to the amp, my question is what inputs do I connect my rca's to? The amp has 4 rca inputs and each one is labeled per channel but since am bridging the subs which two inputs do I connect to? 1&2?/3&4?/1&4?2&3?

1-2 and bridge those 2 channels. The other 2 channels will be left unused. What subs ?

4 or 8 ohm subs ?

I am honestly not sure but I tried channels 1&2 bridged and the sound quality was not very good, no bass really I can hear the voice more than the bass.

Really depends on the subs voice coils. If 4 ohm subs then you'll need a different amp If each sub is an 8 ohm sub then + to + and - to - on each sub and then to the + of one channel of the amp and the neg of channel 2 of the amp The amp isn't a very good amp. But should work if the subs are single 8 ohm subs Pics of the subs. Also pics of the amp and bottom of the sub motors will help

What do you have your amp switch on?HPF/FULL/LPF?If I'm reading this correctly I'm assuming you have your amp on HPF/FULL,you shouldn't be hearing the voices through the subs and turn the switch to LPF.
