ohm question

[acold7dusta 10+ year member]

i got a question on wiring. My 400.1 has the speaker outputs as + + - -. I have a dual 2 ohm sub (diamond D6), and wanna wire down to 1 ohm. The problem is, i dont know if i should prewire it to 1ohm, and then connect it to either of the + -, or if i should run two runs of wire, one to each voice coil? Ive heard that when the subs outputs are like this, they are wired internally for a parrallel impedance to the amp. If this is true, then if i prewired it to one ohm, and connected it to the amp, it would yield a .5 load, right?

edit

i had each voice coil on each speaker outputs, and it wasnt very loud, but it did sound AMAZING. i just wish i didnt have to crank up the gains to 1/2 to even begin hearing it.

Since it is a monoblock amp, you could do it either way. Run the sub @ 1 ohm, then put on one set of terminals, or wire each VC to each set. It doesn't matter which you do, they will both yield 1 ohm @ the amp.

Try setting your gain with a DMM. My last amp was @ 3/4 gain till it sounded good.

parrallel the speaker coils together for 1 ohm,then use 1 set of wires to connect it to ur amp,1 to positive and 1 to negative,both positives and negatives are the same on the amp,they put 2 of each in case u have more than 1 speaker so all the speaker wires can fit.

alrite thanks, right now each coils hooked up to each set of terminals, so im assuming thats 2 ohms right?
