Well the links I posted, had 2 kicker 12" L7's in a kicker box, 2 or 4 ohm, they are priced right under $500 New. This is why I asked about them, also 12" L7's are rated at 750rms each. That makes a combined total of 1500rms watts needed in an amp. As for the big 3 upgrade, I plan on putting more money into my system as time goes on like I said, I am starting a new job monday that is stable and pays well. I think I will go with new, less issues to worry about + having a warranty is always nice
