i.b. 18s...or sealed 15s...that is the question ...

[pickup1]

Got a chance to buy some i.b.18s for my altima ...debating to do those or 2 15s in sealed..got 2 polk 15s sitting here now...and have enclosures for them...
The 18s will be little work to put in...really don't have the height ...but could angle them to possibly fit..
Would be nice to have "big bass" but not a big enclosure...
Thoughts...opinions....

no question, IB 18s.

Only thing i worry about is being sloppy and not having the ability to play cleanly ...

if you seal it up right, (2) 18" IB will have more output than (2) 15" and sound just as good. and as an added benefit they will require less power to it.

I have a crescendo bc2k...think i should get an a/b amp for the "snap"?

[benny]

Nope, I wouldnt replace the amp.

Interesting to me.
I was headed towards sealed 10"s but am really looking at IB 15"s.
Says my trunk provides 15.7 cubic feet of luggage space with no pass thru.

Shoot, if you can make those 18's fit definitely do that! What are they?
