Hey guys, just got this box:

http://cgi.ebay.com/05-06-07-FORD-MU...#ht_3775wt_905

and I currently have this amp Alpine Mrp-650

and my question was would this sub be ok, 400 Watts RMS, 800 Watts Max

any help would be appreciated it, also what would be the best way to wire the sub to the amp..sorry I know nothing about this..

are you going to be using one sub or a pair?

For powering one sub you either need to use SVC to get the 4 ohm load from the amp or change one of them. This amp is too powerful for the sub and with a DVC setup you will be pumping 600 Watts RMS @ 2 ohm from the amp.

the reckfort website has a nice wiring wizard that will show you how to do the wiring. Here is the link http://www.rockfordfosgate.com/rftec...1&woofer_imp=4

its going to be one sub, I am not looking for crazy amount of bass, just a little bit. Should i get the 2ohm or 4ohm sub??

Would this be a better choice of sub for the amp?

Power wise this would be a good match with the Alpine amp. If you connect it like option 1 in this link

It will create a 600 watts RMS load @ 2 ohms.
I am not familiar with the type R sound quality but based in the sensitivity I’d look for something that is over 90 dB.
As far as getting 2 ohms or 4 ohms subs, there would be no deference as long as the power is matching with the amp. Most of the mono Amps support 2 ohms load and some even support 1 ohm load. If you decide on either 2 ohms or 4 ohms the most important thing is the wiring of the sub to the amp so you get the correct load and impedance.
Here is a nice link that will provide you with good information on power matching and wiring.

I hope this helps.
