I thought my audiopipe amp was dead but it turns out the chassis ground was corroded to all hell (wasn't liberal enough with my application of dielectric grease). Cleaned it up and it works flawlessly. Now to decide if i should return this Hifonics BRX1516.1D. If they only give me credit to their website then I'll use it to grab a 2nd audiopipe and push a nice 2500RMS to these 2 type R 12's
