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

I dont no what phase is what do i needa set it on? i dont no much about the other knobs. i read a guide on settin gain. but what about the frequency and EQ?

ty its kinda sloppy but im anxious to figure out whats rong.

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.

2 dvc click rockford link thats how its wired

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.
