Yes you can use it for two subs.
No you can't use it for two DIFFERENT subs.

Two different subs won't damage the amp if the total ohm load is ok but it will:


A. sound bad

and

B. possibly damage the subs if they are different impedances

Correct M.S. I just figured it was a bad enough idea to just say "can't do it"

they are single 4 ohm? wire them par/par to a mono amp to a 2 ohm load.

yes they are single 4ohms. so thus it mean the subs will be fine on the amp or i have to get another vibe single 4ohms and hook them both to it

buy another vibe even if it doesnt wreck your subs itll sound like sh*t. easiest way if they're in the same box use your left positive and right negative off your amp then in the box run positive to positive on both subs and negative to negative on both subs. this gives them both the same amount of power but no matter how you do it using two diff subs wont sound right and you wont push your vibe to how loud it can go because your alpine could blow :P
