Thats it! thanks! looks like this will be my new amp. my Rockford t5002 took a dump today //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif i did torture it for 3 years, not bad fora referb. oh well it was either get another t5002 for $200 or a t8002 for $375 or this lanzar for $250.. hope i made the right choice! 1300w is perfect for my 2 idq12s on the way.

another question the t5002 still puts out to the subs its just totally distorted sounds horrible. ive never had a amp do that they either stop working all together or not any ideas?

would it be better to get dual 2ohm IDQ12s and run 750x2 @ 2ohms each or get dual 4 ohms and run it bridged at 4 ohms?

other options are but i doubt any would put out any power close to the lanzar

HiFonics ZXi1308

Autotek AT1500

Cadence ZRS-3002 (way over budget)

how about the lanzar OPTI600x2HC is this a newer model? http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?Source=googlebase&ProductID=16461

another amp option is the cadence ZRS-3002 and is less then $400 new also
