Hi, I recently bought two 10's kicker comp

http://www.kicker.com/comp

and I can get a deal on Alpine MRP-M500 500w RMS

My question is will this amp be good enough for my subs?

or i just found this

The Alpine one will work. Don't get the Kenwood because it is 4-channel which shouldn't really be used for subs.

how about this

Your RMS is 250 so x 2 would be 500 watts. Look for an RMS amp at 500, the alpine looks ok. you can even do 400 but 500 is optimal. its also best to use a monoblock amp. not a 4 channel, thats better for cabin speakers. although you could use it, its not the best. if you also research on amps, the way it is wired and if your speakers have wiring options, you can get the right setup to match or achieve what you want, for example depending on the way you wire your amp channels, you can get the most bridged, for the subs some have a 2ohm, 4ohm, etc. configuration. good luck.

I like Alpine. I set a buddy up with that amp and a 12" Type-S for his Rolla a bit ago. It bumps pretty well. For two drivers, though, id look at a different amp, definitely not a multi-channel.
Like the Alpine, youll prob want a monoblock that is 2 ohm stable and run them in parallel. I lean towards overpowering drivers by a little more than undershooting or aiming for the recommended values. By the time you add in resistances from your wiring, turning the gain up on your amp till it most likely clips a ton, and most likely <4 or 5 v preouts, youll end up happier with more power because your amp wont have to work as hard in the long run. Youll get better sound and a little more bump as well. The drivers will be just fine as long as you dont push too much more. All the in-line resistance will pull down your actual output a little anyway. I run ~500 rms to my single 10" and its run well for a couple of years so far.

Try looking into this one:

I would get the alpine amp since I have the mrp-m500. I'm only running it half way turned up, but it's pushing two 12 inch Kenwoods really well. The kenwoods can handle up to 400w rms each.

You guys gotta go big like me 2 15in Kickers with a Crunch P15 1500 watt amp hooked up to a sub "volume" knob. With that I also have Apline speakers in the front, and Rockers in the back. If you can't tell I'm kind of a audiophile.

I ran all my cords on drivers side trim with the cables splitting and going where they need to go under the rear seat. My amp is also grounded on a bolt under there.

is this good for my subs? quick response please... meeting the guy in an hour

Run a 4 AWG cable to it and it should do fine. The one above is a 2-channel. The monoblock would work well. The 2-channel would be too small.

this is the one im going for... thoughts? thanks in advance.

The alpine amp is what I am currently with mine. It's loud! Haha.

Haha, I've been calling up the local junkyards that have a collection of front end wrecked (idk why they always are) celicas to find the cheapest. Once they all tell me thats a negative (which they probably will) I'm gonna start looking on ebay, and if thats too sketch I'm gonna use that site you recommended to me. I appreciate it man.

Back on subject, ilmatic, did you buy that amp? If so hows the wiring going? Sound good?

4gauge is a good main power wire, nice if its straight to the sub. if you must power distribute it make sure your main wire is the bigger one for example 4gauge splits into two 8 gauge with a distributor block. it does pretty well on my 2000 watt sub.

I agree. I used 4 gauge for mine, and I have no problems at all. The subs are hitting like they should and maxing out (my controller turns from green to red when max power is drawn) no issue.

a gauge bigger than 4 is pretty big. you'd have to be running godzilla's sound system or something.

whats wrong with using a 4ch if say... you had 2 dual voice coil subs

Ive seen a few fried voice coils from people doing the multi-channel amp/dual voice-coil thing... If the channels arent gain matched, it makes for a nice paperweight... Monoblock is a safer bet for most people.

but theres only 2 lots of settings not 4?

1&2: low pass, high pass, gain

3&4: low pass, high pass, gain

though if you're talking 1 sub with 2 bridge sets then you may get that problem

But in the past I've run 2x10" single voice coils with 4ch bridged to 2ch

Be sure to build the boxes for the kicker woofers to specs included with the packaging cause, if its not the right cuft and have the right size port its gonna sound sloppy no matter how much power you put to it
