i dont really have the time to look up amps for you...but what you want to look for is about a 300-350 watt amp at 2 ohms
thats rms power
peak power means NOTHING...no really..it doesnt...
its how companies like sony sell their stuff
brands to look for
rockford fosgate
mtx
us acoustics
profile
make sure the amp is capable of being "bridged" which most are...and should not be a problem...if it doesnt say...just ask up and someone here will know
if youll go to www.crutchfield.com and look around at their amps...they have a huge selection and if u have any questions they have a great customer service line thats open late
or you can always post here
if you find the amp you want and want to make sure its right for your speakers just ask us
when you find the amp you want check out these websites for it...if they have them they will almost definitely be cheaper than anywhere else you can find
www.carmedia1.com
www.electronicscity.com (im not sure if they sell amps..but i bought my radio from there and it was REALLY cheap)

feel free to ask if you have anymore questions

i have a pair of gxr 12's and i had an mtx 4250 mono block amp running them and they sound great. its like the last guy said something running 300-350 watts but the quality of the amp is a key thing.( example ) dont buy cheap like jensen or some cheap brand cause it does matter. i probably wasnt much help but that i would reply.......peace :cool:

the mtx 4250D is approximately 300 - 350 watts rms at 2 ohms and 14.4 volts. so cody's statement holds perfectly.

Alpine MRP M-350 (350 x 1 at 2 ohms) -- 200 bucks at crutchfield.com
MTX 311D (310 x 1 at 2 ohms) -- 220 bucks at crutchfield.com
MTX 250D / 4250D (300 - 350 x 1 at 2 ohms) -- ebay it for about 150 / 175 -- its old stock everywhere else.
Profile CL600M (450 x 1 at 2 ohms) -- 169 bucks at crutchfield
RF Punch 301M (300 x 1 at 2 ohms) -- 199 @ crutch
RF Power 351M (350 x 1 at 2 ohms) -- 250 @ crutch


any of those will work... I'd go with the alpine mrp-m350 or the mtx4250d for sake of price and the best power. profile isn't anything special.

there are far better amps out there, but they're gonna cost you... one of these days someone's gonna knock me for readin right outa the damn catalog, but i really don't care -- fact is, they're cheap, they do the job, and they're easy to find... so voila.

Hey i was looking around and i found a Power Acoustic amp that puts out 820watts max and 180x2 @ 4ohms, for $124.99 is that a good deal or not. I found it at www.justamps.com

sntnsupermen131

truthfully...from what i can tell...almost all the amps on that site are junk
go to www.carmedia1.com
on the left side it says car audio
click that
then it gives you a list of different brands
on the top click alpine
then click on amplifiers
the third amp down is the Alpine MRP-M350 Mono Amplifier
its $149.00 w/ free shipping
that is a great deal on that amp
i really do think that that is the best amp for that price and your set up

I was looking on that site and i found the Pioneer GM-X972 2 Channel Amplifier it puts out 150x2 (4ohm) 200x2 (2ohm) continous power for 119.00. I guess what i want it the most bang for the buck, im sure you guys feel the same on that one.

Systems

I have another question, there are alot of wires out there to hook up amps with, does it matter what you use or is quality a big issue when you hook up your system with wires and what would you guys reccamend to use.

hey steve if you're gonna go with that pio amp.. thats fine.. just get the dual 4 ohm coil GNX's -- that way you can series / parallel them to a single 4 ohm load -- that way u get 200 watts per sub instead of 150. now THAT is the best bang for the buck.

far as wiring - you'll need an 8 gauge wiring kit for that amp. the cheaper the better... just make sure its not thick windings in the wire -- that stuff sucks... fine thread/winding 8 gauge with a 30 amp fuse ought to be fine. lightning audio / streetwires / fosgate / stinger / scosche...

stinger 8 gauge at sounddomain is like 0.75 cents a foot. look for the cheapest fuse holder on earth and two ring terminals and you're set --- get away a lot cheaper (and with ebtter stuff) than a pre-made kit.

I already got 2 GXR 124's, would that Pioneer amp do the job ??

PoweredByDodge

ya -- the pio will work... 150 is allright for those subs. i didn' tknow u had the subs yet -- if u didn't obviously the 8 ohm would give u 50 watts more a sub, however, considering u already do... 150 watts a sub is close enough to the recc 175 to do fine.

Systems

Couldnt you create a 2ohm load with the 2, 4ohm sub to create a 2 ohm load and then it will put 200watts into each. I think ya can do that unless im mistaken.

PoweredByDodge

to get 200 w to each sub you'll need to either...

1- put a 2 ohm load on EACH channel
2- put a 4 ohm load on the BRIDGED channel


two 4 ohm speakers = 2 ohm load.

so you've got one two ohm load... you can put that on one channel... and you'll get 200 watts out of that channel, but since there are two speakers on it, you'll only get 100 watts per speaker.

if you put that 2 ohm load on the bridged channel, you would most likely fry that amplifier, as it is only rated to withstand a 4 ohm load in bridged mode.

typically, people buy 4 ohm subwoofers in pairs when they are using a mono 2 ohm stable amplifier.

in contrast, they buy dual 4 ohm / 8 ohm subs when they are using a 4 ohm stable bridgedable class AB amplifier.

obviously this stereotype does not hold true throughout, but in the case of entry level, its true as true gets.

Systems

So i should just hook up each speaker to both channels to get 150watts rms to each, will that be enough to run them ??

PoweredByDodge

ya just wire one to each channel - so u get 150 / sub... that'll do it dude.
