4ohm SVC on 4ch..?

[DetoxLS 10+ year member]

Can I run a 4ohm SVC sub off of 2 channels of a 4ch amp? If so, the (+) goes to one channel and the (-) goes to the other?

Find your user manual.. and see how the manufacturer recommends that you bridge the amplifier. Then yes you can run the sub on the two bridged channels.

So if the other two channels are at 4 ohms per channel, its a must to run the 1 sub at 4ohms? rather than at 2 ohms bridged?(with a dvc)

You can't change the impedence on a speaker man. so if its a 4ohm speaker... than no.. you cannot run the amp at 2 ohms unless you get a second sub to match the first and wire both of them together creating a 2 ohm load.

What about one 4ohm+4ohm dvc? It can be wired to a 2 ohm load. But not if the amp is running 4 ohms for the 2 front doors?

I wasnt implying that i could or wanted to change the impedence on a speaker. My question is if i can run one sub on the amp with a 2ohm impedence(meaning 4ohm dvc) while running the 2 front door speakers at 4ohms.

^^^^ x 2

find the manual... see if you can bridge the channels @ 2 ohms... chances are probably not... so just get a 4 ohm SVC or a 2 ohm DVC sub and bridge the 2 rear channels at 4 ohms

the manual doesnt say..its not that big..I know the amp will run at 2 ohms. The problem is that im trying to run it at a different impedence than the front, right?

no... the amp is 2 ohm stable... but not 2 ohm stable bridged... what kind of amp is it?

I see where it says 160x2 at 4ohms mono...WHat makes it mono..any certain setup?

bridging makes it mono... u can bridge the rears **or fronts** for 160W @ 4 ohms

you could run the fronts stereo at 4ohms a side. and then you can bridge the rears and run them at 4ohms as well... not 2ohms though, because in bridged mode that amp will not support 2 ohms.
