how should i wire my sub for my amp?

[LowEnd85 10+ year member]

its a profile audio 400MSX mono amp, 600max @2ohms and 400max @4ohms. my sub is a mach5 MAW12, rms is 350watts. should i wire the sub for 2ohm, or 8ohm, the 2ohm load gives it double the power, if i wire it for 8ohms i should be able to turn all my gains up and produce a max of 400watts, 50 more than the rms of the sub which should be ok. alot better than 250 above the rms rating

I'm guessin ur sub is DVC 4 ohms? just wire it to 2 ohms. Then set ur gains accordingly

Sqrt(350x2) = 26.5v

i dont have a DMM. im setting gains by ear

you can find DMM for under 20 bucks almost anywhere.

Get one and do it right. you should never turn your gains all the way up, and just assume its gonna be fine

the amp is 300Wrms at 2ohms 200Wrms at 4ohms and 100Wrms at 8ohms

run the amp at 2ohms

put the amp gain at 1/2 and bass boost at +6db and be happy with with it

Invest in one, its only 10-15 bucks. Plus you're not going to be able to hear when your amp is clipping if it doesnt have a clip light.
