this is alittle under the rms but its a good amp
http://www.cbrstereo.com/index.asp?PageAction=VIEWPROD&ProdID=835
its a rockford fosgate 551x
70 watts RMS x 4 at 4 ohms
140 watts RMS x 4 at 2 ohms
275 watts RMS x 2 in bridged mode at 4 ohms
2-, 3-, or 4-channel output
4-ohm stable in bridged mode
Tri-Way capable
requires 4-gauge power and ground leads — wiring and hardware not included with amplifier
MOSFET power supply and output devices
front and rear 50-250 Hz high-pass/low-pass crossovers, 24 dB/octave slopes
MEHSA mounting technology increases the heat transfer from the MOSFET output devices to the heat sink, for higher power output, lower operating temperatures, and greater reliability
TOPAZ — noise-killing differential inputs that eliminate 80% of ground loop noise
Trans•ana circuitry keeps preamp voltages low and signal paths simple for outstanding audio quality
NOMAD — advanced protection circuitry for "intelligent" shutdown protection
wired remote control included for fingertip control of Punch Bass (for 0-18 dB of bass boost at 45 Hz)
preamp-level (RCA) inputs
preamp-level (RCA) outputs
12-1/8"W x 2-3/8"H x 9-7/8"D
should be suffient but if u wanna invest a lil more there a good 4 channel alpine amp i believe thats 80 watts a channel
