whenever i turn the volume up pretty loud with the gain and sub level set fairly high, my amp will go into protec mode. the amp is a lanzar 1200d powering a 12" Brahma @ 1ohm. sending it 1200rms. if i let the car sit and idle for awhile with a little music playing, i can play it loud then for as long as i want. but if i hop in the car and blast it right away, the amp goes into protec. battery voltage reads 13.8 at battery and all the way back at the amp. i read the amperage going into the fuse under the hood and it read a mear 8 amp!!!! that came as a huge suprise to me. i thought it would be a lot higher, and i think it should be a lot higher. another problem is that my batteries ground is shady. there is a half covered ~8awg wire grounding the battery to the motor, and 2 smaller (~6 awg) wires grounding it to the frame. the 8 gauge wire seems to be rusted and its not covered, bare wire. my alternator is a stock 90A and seems to be working fine, im not sure if its large enough. jeeps4u sold me this amp, he ran it at 1 ohm and had no problems. it is 1 ohm stable. why is the amp going into protec mode?????
