I'm thinking of either using the Subthump stealth enclosure which is 1.2 cu. feet (would that be big enough for this sub?), or building a box withe sub facing the back of the rear seats.

anyone built an enclosure for this sub that can maybe give me some advice on the ideal size and positioning.

 

Sealed or ported? If it's sealed it's within Morel's recommendations of 0.7-2.11 ft^3, with optimum being 1.06...keep in mind that's in a test facility as every car's interior will deliver different bass response. For ported they recommend 0.88- 2.1 ft^3 with optimum at 1.59.

 

Thanks Denonite. The Subthump is a sealed box.

 

Generally speaking a rear firing sub will give a more full sound than a forward firing sub. Forward tends to sound weak.

 

I'm worried about rattle and damage if I face the sub into the trunk...
I will be dynamatting the entire trunk, rear deck, doors atc, but still.

Would running a ported box with the port running through the rear deck into the cabin be a good idea for SQ?
