[speedyo 0]

i got 2 RE HC 12s, i have em in a 6 cubed box tuned to 31 hz, wit a mtx 1501d powerin both. I think i hooked them up wrong or something, Cuz my rearview mirror dont even vibrate. and my friend can do that wit 500 watts. i used the wiring wizard at rockford fosgates site running it on 1/0 gauge wire http://www.rockfordfosgate.com/rftech/wiri...x=21&image.y=13. personally, i believe that i should have hooked each speaker to a different speaker output on my amp. Heres some pics ofwaht the outside of amp looks like. http://www.crutchfield.com/S-kNz22QCXzEr/c...&display=XL#Tab

What are the coils on the HCs? Also, do you mean you have them wired at 1 OHM? If so, you must change that now. The MTX is only stable into 2 ohms. That could be your problem right there.

Did you use option 1 2 or 3? You should have used option 2

i remeber when i first got my dvc subs i wired the coils to the same side instead of running the wire all the way to the other side. So basically i had one coil playing and it decreased the output by alot.
