i wouldn't say crap. the optidrive models are pretty nice quality...the most popular lanzar is the vibe 1200d. these versions IMO are "you get what you pay for". they are nicely priced but i believe it's not truly stable at 1 ohm mono. a lot of peeps have had problems with this amp. if you want a great amp company for cheap...i recommend autotek. i used to own a sx2300 (1 ohm stable and puts out [email protected] ohm...800w @ 2...700w @ 4). for subs...i would only advise to choose between the street machine or stealth series. but even with the greatest stuff...installation is everything.TITO said:IMO. Crap.
