I got an AudioBahn A4002T amp from a friend for free cause he couldn't figure out what was wrong with it. I don't no if it's a good amp but spec's say it can put out 400rms which is exactly what I want. Anyway, the problem with the amp is when not bridged it works but it doesn't bump to hard. Now if I bridge the amp to get the 400 watts RMS x 1 bridged output It doesn't bump at all. I thinking something is fried in the amp that runs the bridged circuit. I opened it to see if there were any obvious burnt or melted pieces but nothing.

Side Notes: I tested the amp on a Jensen BP210 300rms this is why I thought when not bridging the amp and it didn't bump hard, was because the amp was putting 100-200rms to subs that needed 300rms. The amp I have now is Sony XM754HX running 2 x 200W @ 4 ohms bridged. The sony and jensen together are alot louder and stronger then the audiobahn and jensen.

I'm novice at this stuff so bear with me
