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:
https://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:

Subwoofers:
2 of https://mobile.jlaudio.com/products_subs.php?series_id=24
Recommended 0.625 cubic feet of air space.
5.93 inches mounting depth

Amp:
https://www.alpine-usa.com/en/products/product.php?model=PDX-1.1000&lang=en&tab=F
OR
https://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.

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!!!!!!

yea wow...nice setup but.....you dont need that much power. you only need about 500 watts total to run those subs. You would probably run a large chance of blowing those subs with both alpine amps. Check into a smaller version like the mrdm605 or the jl 500/1. Not a big fan of kicker amps...but just my opinion.
