Need help for friend

Would like advice on my friend's subs and amp combo

He has a car with a sealed trunk and is looking for a 60/40 SPL/SQ set up.

He can spend about 1200 dollars on subs, sub amp and a box. Would a ported box or a sealed box be better for his trunk to prevent rattle but keep them hitting real hard so they shake the pasengers.

Right now he's looking at
2 12" Brahma's
2 12" Eclipse Titanium's
2 12" ID Max's (My highest rcommendation for him for price and application)
2 12" JLw6v2's (overpriced...)

Also we're looking for a good amp choice to help power whichever sub you recommend. Thanks guys!

prevent rattle? I'm not sure what you mean

All of those subs are going to rattle the crap out of his trunk ported or sealed without a ton of sound dampening.

I meant more of which enclosure will maintain the true sq and spl of the sub, a sealed box or a ported box. I have never had much experience with closed trunks since all of my applicaitons have been hatchbacks and open trunk suvs.

So which subs would be good for his liking...a 60/40 spl/sq set up. He wants a sub thats going to make his body pund when the subs hit. So sealed or ported, which subs would you guys recommend and which amp. A total of $1200 for subs amp and box. Any help is greatly appreciated.

ported, single mtx 9500 or SS mtx9500
ported MT or SS MT

Is SS single sealed?
