how do they sound? are they a was of money when i can get a box custom for some regular 8 inch subs

 

Well I have been working with car audio on and off since high school ( 20 years ago ) and a lot has changed in that time. Its just like they say about a engine " there is no replacement for displacement " if you will have it that way. If I were you I would go with as big of a normal sub as I could fit.
