That's better, that should be fine bud, might be a little bit much port area but since you are running on such low power I don't see it being an issue

Do you think those things could take 2000wrms? like a hifonics amp or something? they are 500w to 1000wrms and btw i do put my stuff in my moms SUV some times and run a wire from my house to the hatch but my parents just think im an asshole who listens to music because it shakes the house or else i would have it hooked up in there with a nice amp.

Which alpines are they? The type S or R's?

Also final impedance with the 2 subs together will be 2 ohms, so whatever hifonics amp you are looking at isn't going to put out 2000wrms at 2 ohms, it would be at 1 ohms that it could do that amount of power.

And if you want a flatter response out of that box and you are planning on hooking more power up to it later you might want to drop the port area down a bit, maybe between 14"-15".

Also double baffle on the front would be a good idea

alpine type r 12''s dual 2 ohm on each so if i wire each sub in parallel to 1 ohm than wire them together wouldent i get 1/2ohm final impedance?

2 ohm or half, but to run half an ohm you would need an amp capable of handling that low of an impedance, and the electrical power to back it up.
