Okay, so I fried the Mono channel on my amp..was running my two Audiobahns in Series giving the amp a 2 ohm mono load, which was fine according to the specs of the amp. Ran it like that for almost a year and a half and was great, then one day I lost all my sound...no go boom no mo! Rewired the subs parallel and now have them running 2 ohm stereo off the two regular channels of the amp...again, fine by amp specs.
Problem is though...I have NOOOO low end response anymore?? What gives? Any suggestions??

probably because you no longer have as much power.
maybe you have the amp on highpass or the lpf is turned too low, or isf too high.

Ehhh...NM, I figured it out. Had a brain fart. First...let me correct my miswording in my first post...I had my subs bridged on my two channel amp. Through some troubleshooting I discovered I blew the left channel of my amp, bummer huh. Now...cause the subs are sharing the same airspace, it looked like they were both being powered, but one (the one on the blown channel obviously) was simply acting like a passive radiator. So I was only running one of my subs in that big ass box...48sq IN of port and a big ol passive radiator too...sounded like poo poo!!
Tomorrow Im gonna take one of the subs out, cover the old hole with some MDF and try tuning the port and maybe get some siiiick low end response out of that box?!?

Hooooly cow balls...so I did some math this morning and decided to give it a whirl. I covered up the old cutout for one of the subs, and reduced my port size from 11hx9d3w to 3h9d3w. Now, the box is roughly 2.75 cubes and with the new port, ive got it tuned somewhere around 27-30hz...best low end Ive had in a while off a single 12..dayum! Oh Im running an Audiobahn AWT1251 and an Interfire IB2900C. The Sub is getting about 350 RMS. Looks a bit ghetto...but hell I dont care, I got my siiick low end I was looking for.
