Rockford Fosgate 'The Punch' 8 Ohm SVC 10s. These eventually got sold to my ex-landlady.
I then went to these ~ Kenwood eXcelon KFC-Xw10dB 4 Ohm SVC 10s.
The above was cross-trained and now serves duty wired in series attached to the sub channel in my HT...they had to come out of the car to make room for:
I've owned these bad boys (along with a brand new lanzar opti4000d) for over a year now, and have yet to have a dependable to car to them in.
I don't even know if they work..... Never even hooked up a 9v to them to make sure they're wired right...... But i think this summer i'm finally going to get them singing!!! Soooo excited.
It's been my dream since high school (2003) to own and run an opti, and it's been one long string of setbacks. (I once owned a opti2000d for about 3 days, until they blew my subs almost instantly, and i couldn't afford to replace my subs AND keep the opti.) But from what a remember, it was the most intense assault on my ears & car i've ever experienced.
