need help with a box design/amp suggestions? 2 sa 10 d4 in a 97 mustang

upgrading alternator this winter. (250 amp)
already have 1 run of 0awg from batt. along with alt i will do the big 3 upgrade.

just looking for best output for these woofers i know they can take 1000 rms easily if powered correctly and im open to any box ideas and amplifier suggestions.

keep in mind i have a mustang so the trunk space is limited.

any suggestions will be helpful, thanks!

anyone?
