anyone here have any experience with DD subs ??

or known anyone who has.....?

 

I use to have the 3515. What concerns do you have?

 

I have/had a 9515. I blew it but that was my fault. They are suppose to handle a lot of wattage. I was running a powerbass 3000da with it. I had dual 1 ohm voice coils. At 2 ohms is 2000 watts (or something close) and it easily handled it. I wanted to blurp it at .5 ohms. That would have been nuts.

 

crazy power great sound lots of cash but really good subs

 

good friend of mine has their flat carbon 15 in the tire well of his civic, and two of their same 12's in his integra . sound great and hes had em about 3 years, no problems.

 

See for yourself.
