The 1200.1 is stable at 1 ohm...some people have problems, some people dont.

ya, but I want to (as I would think everyone else would) play it safe and wire it in 2 ohms.... is it possible or not with 2 subs that are 4 ohm DVC??

2 x DVC4ohm subs will wire to 1 ohm, or 4 ohm.

so there is no way to make 2 4 ohm dvc subs wire into the amp for 2 ohm load??

Originally posted by drasik That is thrue the 1200.1 is not stable at 1 ohm. It will clip for sure at any longer use of the amp. It'd keep it at 2 ohm load. //content.invisioncic.com/y282845/emoticons/nono.gif.eca61d170185779e0921b0faa9704973.gif

how do u figure it'll clip??? clipping is based upon the gain settings......so if the gains are set correctly the amp wont clip....and yes the amp is stable at 1 ohm....its 2ohm optimised but stable down to 1ohm.....geesh people....please read up on the amp before u post things about it

this is what my wiring terminals look like. then ill just hook up the positive and negative to my amp.

should work jus fine.....no real need to bridge them....only need to use one channel....but that works as well

Nope, there is no way.If you want the amp to see two ohms, you have to buy two 2ohm dvc subs not 4 ohm. You serial each 2ohm sub to 4ohm, and then you parrallel the two subs together to bring it back down to 2 ohms- simple.

 

and the best part is that most companies offer the same model with 4ohm dvc or 2ohm dvc at the same price.

 

hope this helped you out.

well, what can i say...the guy at CC is an idiot. IF the 1200.1 was a 2 channel amp that would work...you would be running 1 sub @2ohms to each of the 2 channels. BUT, the 1200.1 is a mono amp...like goddyd said b4 the 2 sets of terminal are just for convenience sake. The amp is internally bridged in parallel...so if u wired it like that it would be a 1ohm load. peace
