That amp is only 4 ohm stable bridged, but I am assuming that you are talking about a Type R subwoofer. In other words, if you are planning on driving a subwoofer @ 2 ohms, my answer would be NO.

for $300 I would go with anything above except the kenwood... with the kenwood you would have to run it stereo & only get 180w per coil... barely moving the sub....

Onlinecarstereo.Com - Wholesale Car Audio/Stereo Deals At Bargain Prices, www.woofersetc, Car Audio wholesale distributor Alpine Pioneer Kicker Clarion Hifonics Kenwood Boss - Ikesound.com or ebay.com... for $300 you can get one hell of a d-class mono amp that will put out at least 500w in 2 ohm mono...

The kenwood isn't even the best choice for the money FROM crutchfield... they must be running an internal contest or spiff on Kenwood's amps to drive kenwood sales... lol

from their webpage the Alpine Mrv-D500 is one sale from $199.99!!! 5 times the mp the kenwood is. Same with the Rockford PRime-500 $199.99! the kenwood KAC-9104D is $299.99 for 900w.... those are all from CRUTCHFILED's own current online prices! Dumbasses..

There has GOT to be a spiff or promotion in the slaes department for them to push such a ****ty choice... lol tooo funny.

I will include the original box, packing and manual. If using buy it now I will include Rockford Fosgate #4 wire kit with 2 inline fuses as well as a grounding block and a #4 wire to #8wire distribution block.

How about something like this? $249 Shipped and looks to be excellent build quality. I seen a few recommendations from some posts on this board saying it was a pretty nice amp.

I like Kenwoods for cheap amps, like alpines better but usually more cash. However if I were buying an amp that size right now I'd buy this: Pioneer Premier PRS-D2100T (prsd2100t) Class D Amplifiers Car Amplifiers Car Audio and Video - Sonic Electronix
They even have an open box cheaper yet: Pioneer Premier PRS-D2100T R/B (LS-prsd2100t-RB) Class D Amplifiers Car Amplifiers Car Audio and Video - Sonic Electronix

IIRC it is just last years model. But its a full range class D you can use it for subs or full range, takes less power, smaller, Icepower, 2yr warranty, etc., 600rms x1 @4 ohms. Hard to beat that deal with a stick. lol. Alpine PDX are Icepower too.

Is the sub 2+2 ohms DVC? If a SVC 2 ohm then you need a sub amp or 1 ohm stable 2ch.
