Pioneer UD-SW250D reviews
Great space saver in old 4runner. Paired with JBL shallow sub. Sounds really good.

Very well made, looks great, comes with plenty of hardware. Put a shallow mount speaker and you have a great box.
Pros: looks and durability

Just buy the pre-loaded version rather than the sub and speaker separate. It works VERY well with the Pioneer slim sub and is matched perfectly for the sound the sub produces. There is no advantage to buying them in two pieces.
Pros: Size, sound, build quality
Cons: Specific to Pioneer speaker, cost

I purchased this frkm another retailer to fit a kicker sub i got from Crutchfield. The box is very nicely constructed. But the cutout for the sub is 9 3/4' and most 10' subs need a 9 1/8' cutout. I ended up having to get an adapter ring to neck down the opening which in turn defeated the purpose of being a down firing box due to the speaker now sitting 1' further out. The box was designed to be a perfect fit for the pioneer shallow subs so keep this in mind before you purchase. If you dont mjnd a little work to make it fit its a great box for a shallow sub. If not look for another box because i would not use the pioneer shallow sub just to use this box it just can not go low enough to sound like a sub should.
Pros: Good build quality
Cons: Designed by pioneer to only fit their non standard sized shallow subs. Has to be modified to fit standard subs due to cutout size.

Very nicely constructed box. I used it for an 8 inch standard sub, for which the air space was perfect. I made an adapter out of 1/8 inch plywood, and it sounds great.
Pros: Solid construction.
Cons: Air space a little small for a 10 inch sub. Only fits a very narrow speaker.
