2 amps.... one for mids and highs..... and one for subs........ all the details are below.....

MIDS\HIGHS amp

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

SUBS AMP


Detailed Description
Key Features:

140 watts RMS x 2 at 4 ohms
275 watts RMS x 2 at 2 ohms
550 watts RMS x 1 bridged output at 4 ohms
stereo or bridged mono output
4-ohm stable in bridged mode
Tri-Way capable
requires 4-gauge power and ground leads — wiring and hardware not included with amplifier
variable 50-250 Hz high-pass/low-pass crossover, 24 dB/ octave
TOPAZ noise-killing differential inputs eliminate 80% of ground loop noise between the head unit and the amp
NOMAD advanced protection circuitry monitors temperature, voltage, current and impedance, and provides "intelligent" shut-down protection without limiting system performance
TRANS•ana circuit designs keep voltages low and signal paths simple in the pre-amp section, for minimum distortion and maximum musicality
MEHSA provides more efficient transfer of heat from MOSFET output devices to the heatsink for cooler operation
preamp outputs for convenient daisy-chaining of amplifiers
Punch Bass boosts bass up to 18 dB at 45 Hz (wired remote control included)



Prices of the amps on a couple sites are around 300 EACH..... search for them on google......... ROCKFORD FOSGATE 551S and 551X
200...........

buy this shit

 

200 for both or each? big difference

 

both for 300 1 for 200 :> pmed u also
