purchases for my stereo, 2003 GMC Sierra

stereo. I have a 2003 GMC Sierra. 600 CCA Battery with a 105amp (i believe, not 100% sure) alternator. This is the box i have: http://www.subthump.com/ctbamp.htm 6.5 inch mounting depth. Each side has .70 cubic feet the amp area has room for an amp up to 18 by 15 inches. These things are what i based my amp and subs on. This is the head unit i will purchase: http://www.clarion.com/ca/en/products/2006/audio/source_units/cd/DXZ865MP/ca-en-product-pf_1138706936844.html Subwoofers: 2 of http://mobile.jlaudio.com/products_subs.php?series_id=24 Recommended 0.625 cubic feet of air space. 5.93 inches mounting depth Amp: http://www.alpine-usa.com/en/products/product.php?model=PDX-1.1000&lang=en&tab=F OR http://www.cardomain.com/item/KIC04SX6501 What i need to know: Which amp would be suitable for these 2 subs?    What size power wire and fuse would be most appropriate. And can any of you offer any other suggestions that will fit the box requirements and cost similar in price. Withtin $100 or so for each item. Thanks.

One of the amp links was broken. here are the amps i am looking at: http://www.alpine-usa.com/en/products/product.php?model=PDX-1.1000 http://www.alpine-usa.com/en/products/product.php?model=MRD-M1005 http://www.cardomain.com/item/KIC04SX6501

And based on your choise of amp, should i pick up the subs in DVC 2 ohm or 4 ohm?

with the alpine pdx either 2 ohm or 4 ohm will work since it puts out same rated power at 2 and 4 ohms. I'd get the PDX amp if you got the money...ice power baby...clean and cool...plus it just looks plain badass I'd run the biggest power wire you can...but good 4 gauge will do...100 amp fuse I guess...not sure what 4 gauge can handle. Oh yeah and upgrade your big three!!!!!!
