JL E Class E1200 Monoblock Amp Vs Alpine MRP-M450

freakrz · 9th April 2006, 11:52

hey can some one help me choose one of the two..! which one would be a better option to power up my Alpine SWR "Type R" 12" 1500W Sub..

1) JL Audio E Class E1200 Monoblock Amplifier

» Rated Power (mono): 120 W RMS x 1 @ 4 ohm (12.5V); 200 W RMS x 1
@ 2 ohm (12.5V)
» THD at Rated Power: <0.08% @ 4 ohm (20 Hz -20 kHz)
» S/N Ratio: >104 dB referred to rated power (A-weighted, 20 Hz ? 20 kHz
noise bandwidth)
» Frequency Response: 10 Hz ? 25 kHz (+0, -1dB)
» Damping Factor:>200 @ 4 ohm / 50 Hz, >100 @ 2 ohm / 50 Hz
» Slew Rate: ± 22V/µs
» Input Range:200mV ? 8V RMS
» Dimensions:9.8" x 9.25" x 2.36"

2) Alpine MRP-M450 Mono Amplifier

» mono subwoofer car amplifier
» 220 watts RMS x 1 at 4 ohms (400 watts RMS x 1 at 2 ohms)
» variable low-pass filter (50-200 Hz, 24 dB/octave)
» tuned Bass EQ (0-12 dB bass boost at 50 Hz)
» subsonic filter (15 Hz, 24 dB/octave)
» MOSFET power supply
» CEA-2006 compliant
» STAR Topology (minimizes internal noise and prevents ground
interference)
» speaker- and preamp-level inputs
» gold-plated screw terminals
» fuse rating: 20A x 2
» 8-gauge power and ground leads recommended — wiring and
hardware not included with amplifier
» 9-3/4"W x 2-3/8"H x 9-9/16"D

Forgot To mention the Price..Both are costing me 150$....

low_bass_makker · 9th April 2006, 17:04

go for alpine if u wanna run the sub only.

jkdas · 9th April 2006, 17:05

alpine it should be

mono and 20hz to 20khz for JL???

Autophile · 9th April 2006, 17:06

Alpine any day. Does your R Type sub has dual 4ohms coils or 2ohms coils.

freakrz · 9th April 2006, 21:00

yea..its Dual 4-ohm voice coils, Kevlar reinforced pulp cone.

jkdas · 9th April 2006, 23:11

Dual emm, parallel it and run drive it in 2 ohm; Alpine amp

right guys?

400W > 200W...this might be the whole picture btu take the Alpine even though the Alpine amp is probably rated at 14V not 12.5V.

I buget permits go for V12 MRD-M605 . It best suited for ur sub and a extra headroom for further upgradation

navin · 10th April 2006, 22:50

and the 1005 will offer even more headroom. LBM stick to the query asked! ok?

yea i was thinking of that..its costing me 220$..i have that option too..but the weight limit permits me....("i can only get 50 kilos that is 2 suitcases..")

The sub weighs like 7 kilos..i guess..and i am also getting some components and some momo accessories..if i have enough room for that one..i will surely consider it..

low_bass_makker · 11th April 2006, 10:25

See Navin He is considering my offer !

navin · 11th April 2006, 10:47

Yup! now with a little nudge maybe you can get his to get the 1005 instead then he can drive 2 woofers if he ever needs to! :-)

low_bass_makker · 11th April 2006, 10:50

no no man I only recomended 605 not 1005, Navin Also he would not be able to run two 4+4 ohms woofer with a single 1005 (1 ohms not stable). thats why I recomended 605 to him.

LBM, I was joking. see the smiley at the end of my post.
