I never got a chance to measure the SPL, however they were a considerable amount louder than when running on the Fosgate (I estimate around 142dbs, possibly tweakable to 144). I must note that in the single chamber box I was running them in at that time they produced a decent SPL, however sound quality wasn't all that semi truck repair

None . .

I've gone to Home Depot and had stuff hanging out the windows to fit. Has alot of engine noise for a little car. And it has recently started making a whining noise from the front end...I'm too afraid to ask what that could be. suspension repair

They look great and sound great what more needs to be said there great subs.

I cant find any unless pounding too hard is a bad thing

These are the best subs ive ever used, they dont break down at all unlike some ppl say they do ive used mine for 2 years and not a problem. If you power these subs well they pound like crazy they are a all around great sub but for me they make my car shake alot so i probably should put in a deadener kit just to eliminate the rattling of my hatch, other than that these subs thump hard and dont quit.

none

These are the best subs i have ever used...these subs pound like krazy and if u really want bass use a good amp and put a deadner kit on ur trunk so it elminates the bass...but by far these are the best subwoofers...they kick jbl, sony, and rockford fosgate out of the way

Looks, sound quality

Had them for about 4 months, then the rubber started coming off the cone!!! I dunno if it's the heat or too much bass.

These subs look good, pound good in the beginning, then they just fall apart!

I've used many subs, these are by far the worst.

Nice looking, quality sound, deep deep bass.

The plastic moldings on the side where you screw into the box are kinda cheap.

These subs are good quality for the price and pound pretty damn good. You dont need anything more than 2 of these unless you wanna go deaf or something. I recommend these totally, just get a powerful amp to make these babies POUND.

Nothing these are one of a kind

Doesnt just distort when you put the power to it...stays very, very clean!

None for what they are meant to be! Give them the full weak of break-in and you will be rewarded!

If you need more bass than what this produces then and you plan on staying in your car while listening...I have a few words for you...BellTone Hearing Aids. This sub pounds like mad, smooth and controlled though! Great for the over 35 crowd and the wife can live with it too :)
