What amp would power 2 Alpine SWS-10d4 http://www.alpine-usa.com/product/view/sws-10d4/ ? I was looking at a http://www.kenwoodusa.com/Car_Entert...iers/KAC-9105D or this brand http://www.ebay.com/itm/390624324863

I have no experience with the cadence amp but I had the Kenwood in the past and it pushed my 2 Alpine Type R 12's with authority. I also have used the alpine's you referenced and they have nice sound quality and will get low and loud.

The Kenwood looks good.
I would go with a mono amp that is rated at around 500 watts RMS @ 4 Ohms or a mono amp that is rated at 500 watts RMS @ 1 Ohm.
Just make sure that you wire the subs together correctly based on the amp you choose.

Looks like those subs can handle a high peek but the RMS is what really matters.

You can use this website to help you choose.
