Alright, what I'm lookin to do is runnin to Dual 2 Ohm L7's. And each of these amps can be bridged x 2 at 4 ohms which works real good for me. So which one of these amps is going to be better in the sound quality area, true rated power that the company says, and which is going to overheat the fastest. Here are the contenders........

Rockford Fosgate 851X

• 425 watts RMS x 2 bridged output at 4 ohms

• 2, 3, or 4-channel output

• 4-ohm stable in bridged mode

• Tri-Way capable

• Front and rear 50-250 Hz high-pass/low-pass crossovers, 24 dB/octave slopes

• MOSFET power supply and output devices

• MEHSA technology

• MOSFET output devices

• TOPAZ — noise-killing differential inputs

• Trans•ana circuitry

• NOMAD — advanced protection circuitry

• Selectable Punch Bass

MTX Thunder1004

• 500 watts RMS x 2 bridged output at 4 ohms

• 2, 3, or 4-channel output

• 4-ohm stable in bridged mode

• Tri-Way capable

• PWM MOSFET switching power supply

• Variable (40-200 Hz) high-pass/low-pass crossovers

• ThunderEQ Bass Enhancement (0-18 dB bass boost at 40 Hz)

• Preamp outputs

WHICH ONE IS BETTER!!!!!!!!!!!!!!

MTX amps are the best, their subs not quite. Audiobahn amps are alright, their subs are insane.
