making an amp do lower impedence

thats another problem i was worried about the only settings the amp has is a bass boos from 0db to i think 10 then hpf lpf and full thats just a switch so that wont be hard then frequency that ill be turned all the way down so the only knob that will even be moved is the input level

it would still be beneficial to match the amp correctly. even if the adjustments are bottomed out, the different channels of the amp may still not be matched.

dont touch bassboost. put it on 0. set it to LPF and turn knob to ~80hz. if you decide to run 2 subwoofers on that 4 channel (which you shouldnt but if you must, then thats fine i guess...its not my car) then you better tune the gains EXACTLY the same with a multimeter or else cancellation may/will occur.

i have a multi meter i just need to find it that way i can get things right what exactly causes cancelation ?

I picked up an MTX Sw1212 powered subwoofer today. This thing sounds amazing. 130 watts, 12" woofer with a passive 12" woofer tuned to 27 hz. Moving the pictures on the walls and my girl got wet from the bass when i showed her haha. Tonight should be good haha.

Series the coils for 8 ohms/sub then run a bridged pair of channels to each sub...

This makes the most sense to me. VC1 on the L channel and VC2 on the right channel sounds like it could get (or sound) ugly.

i had this amp in my car before having 2 chanells run each coil of the sub and the other 2 running my 6x9s so i dont think things would get to ugly if i get that im just wondering what the power output rms wise would be if i ran them that way each coil to each of the 4 chanells compared to bridged to to each sub at 8 ohms

It would be exactly the same, but since the channels are mono'd (bridged) you won't have to worry about having different signals going to each coil.
