A friend of mine just finished a fairly low budget system in his subaru and he's unhappy with how is lows turned out so he wants me to help him out (sadly, I know more than he does). He says he wants more output, but I know that he is also not a mega bass head.

currently he is running a cdt es sq-80 on a Alpine pdx 600.1. He didn't really know what he was buying when he bought an 8" built for SQ.

He used this thread to build himself the same box:

He was hoping the box was his downfall but I'm telling him he should probably scrap the sub and the box. I think he can build a box to fit inside the wheel of the spare that should suffice.

He's getting back to me with dimensions but I have a feeling he'll need something pretty shallow and not a air space hog. If it's as shallow as I'm thinking, I'm going to recommend the new BM but I feel bad recommending a sub solely on reputation.

how is the alpine amp that he has?

you guys think that original box is a joke?

does that 8" sub he has have any potential of a delivering some decent output?

I'm going to make up dimensions for now and say he has 5-6" of mounting depth and about .7 cu ft to work with...what you all think?

How much space is in that current "box"? He's not getting a lot of output due to it being a sealed box vs a ported box. You might try and add a little polyfill to the current box and see what that does. You also might try building a to spec ported enclosure for the current sub.

The amp he has is fine, it should match just fine with a BM as well. You might also hold out for the Sundown 8" subs. Supposedly they're right around the corner.

I'm not too sure about that current enclosure. So you think that CDT sub has potential for some output?

I'm not sure what it can really do, but modifying the current box will be far cheaper than buying new gear. So you might as well start there.

Is it all frequencies in the lows he is unhappy with or just the really low ones?

he said he is just unhappy with the sub's output. I have not heard it however.

He wants an enclosure that wont take up any trunk space so there are some big time space restrictions. CDT does not have any recommended specs for this sub in a ported
