New System, Having a lot of problems.

no they would just be out of phase, if the subs are dvc4 ohm subs then 1 ohm, 4 ohm or 16 ohms is the only option so 1 ohm is what you want. recheck the entire install.

is the amp new, or if not do you know if it even worked before ?

ahh, that makes sense.

and there is no such thing as a hpf on a monoblock hifonics brutus amp. that amp has enough juice to fry those subs so just recheck all of it.

I'm not familiar with the phase control, I would just adjust it while playing, to see if anything changes. I believe it's pretty much the same thing as swaping + and - around on your speakers. If I remember the adjustment goes to 180.

Alright thanks. I will play around with it tomorrow. I'm gettin mixed answers from my buddy now on the sub wiring. I believe he has the pos and neg crossed between subs. Im going to yank it all out and re-wire at 2ohm a piece, not a fan of 1ohm myself, esp. on his elect. set-up I would be cautious.

also as far as the box i would do 3.5 cf shared not 1.75 each they sound like shit in a box that small.

you cant wire 2 dvc 4 ohm subs to 2 ohms it has to be 1 ohm only the amp connections are combined inside the amp, it has 2 pos and 2 neg for ease of wiring.

Be careful man. You don't want to make a mistake and fry your amp.

he cant fry it wiring the subs he cant get below what the amp is stable at.

its a 1 ohm amp that will run on good electrical at .6

I'm just saying to be careful. Pretty easy to fry an amp if you don't know what you're doing.

yeah i got ya if he dicks up the wiring on anything else he will toast it for sure.

He purchased the amp off of ebay I believe, it was listed as new but has some surface scratched so im guessing a re-man?

I'm completely re-doing the install tomorrow, this is what working at night gets ya.

Would wiring both at 4 ohms be better than wirin them seperate at 2 ohm each?

Just wire them to 1 ohm mono, and keep the gains LOW. If you do it right, and take your time you will be ok.

Thanks man, no not at all. Thats why I quit on it for the night. I dont wanna smoke an amp due to lack of sleep, and light! lol

the only option you have to get any power is 1 ohm wire all the positives together same with negs its the only choice otherwise you will only get about 275 rms to each sub. instead of 800 per sub

Go to rockford woofer wiring wizard. Just google it... It will make it pretty clear.

Sorry man was not thinking at all on that one!For some reason I was thinking i'm wiring them seperate, but their both hooked to the same mono amp, i feel dumb now.
