18 in a trunk car?


Recommended Posts

how close is it to the trunk lid?

sub up port back probably isnt as loud as sealed forward in most applications.

I don't see what's wrong with that, though people would say you can fit 2 15's instead of 1 18', but if it sounds good, then why not.

2 15s is a no go they require 4.5 net each, cant do that.

also it would be at least 5-6 inches away from the port, or the width of the port from the trunk lid

This. You can also fit more cone area with multiple subs in the same space an 18 would use.

cant seal an 18 forward, opening is too small

id rather not go through the hassle of selling it

im going to want 2 9512s then = too much fkn money

Sounds a bit radical, but you could do a cutout for the 18' on the rear deck, that's another idea, seen it done before on one of the build logs.

Yeah, with the 18' facing up in the trunk, you're gonna have one hell of a rattle.

most dont prefer the 18 in trunk box because of trunk rattle alone...if you can seal it forward would be best option....maybe you can slant the sub but most likely that wont work either unless your trunk is pretty tall...good luck
