you got the model number on that one?

jz983

whats THD? and whats the difference between the 12.2V RMS and the 14V RMS. isn't it better if you run at 14V?

will this one get really hot?

here ya go:

MRV-T407

Alpine 2/1 channel Power Amplifier

Perhaps a couple of these would be fine with you, since you asked for dual 10", instead of 12"



It would look like these with the box



JL Audio 10" Subwoofer (10W04) $99.99 or less

125-watt continuous power handling

Four-layer voice coil

4 ohms

Class leading excursion capability

just installed the alpine mrvf-357! kicks ass! sony makes fantastic home video/audio! i know, eveything in my house is sony!.there mobile euipment leaves much to be desired ! even the new xplod crap they are pushing , don't know why either? spend a little extra on the best, and you will never be dissatisfied ! check out my audio upgrades on my sig, the system sounds great, left the bose hu in coz the acura center console is a ***** to pull apart, and needs a custom install, in case you were wondering? peace...kman156

mr tl

ive got the exact same amp MaxxT posted and another v12 amp
its the best out of the list you made. if your using it to run a sub, get the MRV-100M. SAME PRICE/SAME SIZE. dont pay more than $200 for it

when your car is running (driving), you are running the amps at 14.4V. when the car is off (in acc mode), you are running the amps at 12V.....this is all due to the alternator

in other words, you get more power when your driving

another thing, alpine amps are usually under rated. chances are youll get more power than what the specs say

thanks mr tl

i was thinking of that mono one mrv-100m. cuase i only want one sub. but just in case in the future, can you add another amp to that one? like connect it in parallel or something. instead of getting a 2 channel. i know the 2 channel is better the better choice, just want ot know.

jz983

real quick, for the alpine one, the MRV-100M [img]http://ecominet2.alpine-usa.com:7777/img/asb/mrv100mp.gif[/img

"MAX Power (at 14.4V,EIAJ)
Per channel into 2 ohms : 300W x 1
Per channel into 4 ohms : 240W x 1

RMS Power (at 12V,20Hz-200Hz)
Per channel into 2 ohms : 150W x 1 (0.3% THD)
Per channel into 4 ohms : 100W x 1 (0.08% THD)

RMS Power (at 14.4V,20Hz-200Hz)
Per channel into 2 ohms : 200W x 1 (0.3% THD)
Per channel into 4 ohms : 150W x 1 (0.08% THD)"

what do those frequencies mean? in bold? is it saying how low of a signal it can detect and amplify?

and this amp would be good for low bas right? thats what i need. low

mr tl

the 100M is a dedicated subwoofer amp. if you have ANY question that you might need to use if for component speakers, get the 2 channel because this wont work. but you CAN use more than one sub with it

its only putting out one channel, the internal heat stays minimal....therefore keeping sound at its best

im not sure why those frequencies are in brackets in the power spec, but anyway.
my brochure here says that the crossover can be set to 50-200Hz. lets say you have the 100M connected to a sub, you have it at 50Hz(mine is at 55), the sub will be very mild and only hit when you really need it. you wont be able to tell where the sub is located. if everything else is set up properly, it'll feel like the sub is right beside you

now, if you have to set to 200Hz, the sub will ALWAYS hit. when you play music like Dido, the sub will constantly make thumping sounds like, grrrrrrrrrrrrrrrrrrrrrrrr. ya know?

you have to play with the setting and decide where you like it

heres a pic of my 100M and T407



you better appeciate this ****! lol

jz983

whats with all that other stuff? if i just one 100m, do i need like a distributor and all that other stuff?

mr tl

no no no

you dont need anything else
