[QUOTE="jrdnhsnbrg, post: 8145443, member: 643734"] First- my setup. American Bass XFL 12" dual 4 ohm voice coils at 2 ohms Alpine MRX-M100 1000W RMS at 2 ohms mono amp (currently for sale) Eclipse CD1200 head unit Power Acoustik 5 farad capacitor (currently for sale) 6 gauge wiring (I know, too small- will be changed soon.) Custom professionally built 7.85 cu. ft. Kerf-ported box So, a few weeks ago it got pretty hot for Wisconsin, upwards of 95 degrees and I was out driving down the highway, windows down and music up and my sub just stopped working.
