I got this sub for free from a friend, its in mint condition. It says that the sub is suppose to go in a sealed box. My friend said it didnt have much output in a sealed box. Do you think it would sound good in a ported box? Im just putting together a small system for my dads car so it doesnt need to be to loud.

Its not really going to have a whole lot of output. It is a sound quality sub. the specs say sealed

Serious? lol

My buddy bought a truck and it had 2 in it, he didnt like them, almost threw them in the garbage lol

If you were local I would give it to you. What are the subs worth, just out of curiosity?

Used? I'd think about 150 - 200

I believe they are around 300 plus new, unless my local shop marks up a ton

Do you think its worth the time to make a ported box, it might get a lil more output??

I don't see why it would hurt to try. I'd tune it around 37 or so. I'd also try different sized sealed boxes. Bottom line is though, it's not supposed to get real loud. It's good for SQ and I think it would sound great in a truck box or something but I doubt it'll bee that great in a trunk for example

My dad has a older volkswagen golf, so that might sound decent? eh?

The Golf actually might do pretty well in a ported box. I'd try it out if I were you.

If I were you though... I'd sell it and pick up a sub that can handle more power and get louder.

If it likes sealed boxes, get a 4th order design for more output.
