I am about to buy a amplifier for my sub i have 10" Kenwood Tornado 600W sub. Which of these down amps should i get.
1.)Sony XM-280GTX
http://akamaipix.crutchfield.com/pro...280-f_dmt.jpeg
80 watts RMS x 2 at 4 ohms
100 watts x 2 at 2 ohms
200 watts x 1 bridged output at 4 ohms
stereo or bridged mono output
4-ohm stable in bridged mode
Tri-Way capable
requires 10-gauge power and ground leads — wiring and hardware not included with amplifier
MOSFET power supply and output stages
50-300 Hz low-pass filter, 12 dB/octave
preamp- and speaker-level inputs
gold-plated connectors
variable bass boost (0-10 dB) centered at 40 Hz
11-1/4"W x 2-1/4"H x 7-3/4"D
2.)BAZOOKA EL1500
http://cache.bizrate.com/ce/large/7225035.jpg
Key Features:

350 watts RMS x 1 at 4 ohms
500 watts RMS x 1 at 2 ohms
frequency response 20-200 Hz
variable low-pass crossover (40-130 Hz, 12 dB per octave)
MOSFET output devices
bass boost (0-+12 dB at 45 Hz)
gold-plated preamp inputs
amp has a 80-amp fuse so standard 4-gauge wiring kits cannot be used — see "Wiring Recommendations" under Detailed Info for more information
dimensions: 13-13/16"W x 2-11/16"H x 10-1/4"D
3.)MTX Audio Thunder 4122
http://akamaipix.crutchfield.com/pro...6T4122DMT.jpeg
Key Features:
stereo or bridged mono output
Tri-Way capable
60 watts x 2 at 2 ohms
120 watts x 1 in bridged mode
requires 10-gauge power and ground leads — wiring and hardware not included with amplifier
PWM MOSFET switching power supply
Intelligent Surface Mount Technology for cleaner sound
selectable 85 Hz high-pass/low-pass crossovers, 18 dB/octave
preamp outputs
speaker-level inputs with SmartEngage (turns the amp on when it detects signal from the receiver, eliminating the need for a separate turn-on lead from your receiver)
9-3/4"W x 2-1/8"H x 8"D
4.)ROCKFORD FOSGATE 200M
http://akamaipix.crutchfield.com/pro...00M-f_dmt.jpeg
Key Features:

100 watts RMS x 1 at 4 ohms
200 watts RMS x 1 at 2 ohms
requires 10-gauge power and ground leads — wiring and hardware not included with amplifier
selectable 50-210 Hz variable low-pass crossover, 12 dB per octave
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
TOPAZ — noise-killing differential inputs that eliminate 80% of ground loop noise
NOMAD — advanced protection circuitry for "intelligent" shutdown protection
speaker- and preamp-level inputs
switchable Punch Bass boosts bass +6 or +12 dB at 45 Hz
dimensions: 10-1/2"W (7-13/16" without endcaps) x 2-7/16"H x 9-7/8"D
2-year warranty
Please help me desided which one of these four should i get

shouldnt this be moved to the audio/keyless entry threads???? moderators????

what about JBL? They are one of the underated amps out there.. and is usually higher RMS then rated ( been tested by 2 audio freaks in my area ). I would go for JBL.. but out of your selection... I say RF then

I would uggest not getting the el1500 bazooka
I had it in my old car. Withini the first year it brokke twice.
The thing worked great when it did but quality sucked!

gotta love RF cuz they put out a ton of power oh yah and if u want to step it up get the power version its better but costs more i really like the power version cuz it doesnt drain my battery cuz some of my other friends have some powerful systems but their battery drops like crazy but mine stays pretty much in the same place unless im pushing it to the max then it does a little but other than that its great.

I've got the rf 750s pushing my 2 alpine type r 12'* and at night it will make the headlights dim if I crank it to around half or so. Probably need a bigger alt or maybe get a capacitor sooner or later.
