Update on on the arc ks 2500.1...... man what a sweet amp. First hooked it up to my dc lvl4 m2 15. It fried that sub in about 30 seconds ( burned voicecoil). Then i hooked it up on my fi btl 15 and its a perfect match
. I had a buddy of mine clamp it and it it put out 3172 watts at 14.4 volts. IT'S SWEEEEEET!!!!
