It depends on how much you want to get out of that amp. With those sub's being dual 4 Ohm coils you can only wire them for a 1 ohm or a 4 ohm load. If you want to get the most out of the subs, an amp that can hold a 1 ohm load will output more wattage than one that can do 4 ohms. As for fitting them in the seats, you'll have to put them in a enclosures for them to sound properly. It depends on the enclosure as well, but there's not much space for 8 inch subs under there. Maybe some 6 inch subs would work in a custom MDF enclosure. CDT audio makes a good 6 inch woofer. You maybe better off ding a single woofer in the rear of the trunk like the one BSW sells that has a higher wattage rating of about 500 or so watts, but depends on you're taste.
