Keep guessing...
I almost went with Adire or Resonant Engineering before deciding to go with this one. It is touted as an SQ sub, but with a rated 1200wrms going into it it gets plenty loud...

 

Is it an eclipse?

 

Cerwin Vega?

Trying to tell by the frame design but having problems.

 

Interesting setup. I think you need a bigger cap, though.

 

Rule of thumb I have always used was 1 farad per 1000wrms. Yeah, its a big cap no doubt. Since the post has been up for about a week, with no correct guesses I'll reveal that the sub is a 15" Stereo Integrity D2. Specs and more info can be found at http://www.stereointegrity.com I have to say this thing is amazing for only having 1 sub in the car. They are just as tight as 10's that I used to have but go LOW... Lower and louder than other 15" I've had. Well I'm hooked if you can't tell and I'll recommend these to anyone looking for a sub that strays away from the normal mainstream manufacturers. /flamesuit on/
ROCKON!

 

Also wondering if others have gotten above average performance from their systems in evos? Wondering if maybe it is due to how structurally solid the car is. I've noticed extreme volume levels, but as a whole the car can hold it together well with little exterior vibration. (other than the windsheid wipers)
