i just got this amp off of ebay from a great seller. practically brand new. he had it powering 1 12w6v2 for 2 months. cosmetically 9/10 and performance wise 10/10. this amp is awesome but im looking to upgrade my subs again an need some more power. i had a memphis16-st1000D amp and liked it a lot. i want something that will give me the true rms i need. will also trade anything in my sig if needed.
