15's
 

2 alpine type r 15's, anddd 2 alpine v12 mrd-m1005 amps to power them, just askin to see some installls to maybe give me some ideas on how to put it all in :)

IF you could even get them all in the trunk - I seriously doubt A) your subwoofer boxes would be the correct size and B) that there would be enough airspace left in the trunk for the subs to push

I've seen a guy do a single 15 although i can't remember enough about it to tell you what to search for..

I think even putting 2 12"s or a single 15 is already pushing the limits of the 8's trunk.

now if I were you... I'd consider taking the back seats out and building a sub wall instead :)

i agree i dont think there is enough air space in the trunk of an 8. If you want that much base in your car get rid of the 8 and go buy a denali.

Yeah it was a soundstream so when I searched i found this:

It is Steakboy42's car. Nice looking set up too. Just looking at that, it doesn't seem that there would be much more room for another 15 in there.
