Don't know about my 15" Kicker CVRs? I have seen over the internet that there are 07 and 05 models, and each year the subs come in either 4 ohm stable or 2 ohm.
I purchased 2 15" in a sealed box for 150$ the other day from my friend and don't know exactly which they are, just know they are CVR 15", how do i find out more specs? Also what would be a good amp to power both of them at the same time? (2000 watt, 1500...?)
