I have had these for a little over a year now and I must say they are a really good pair of subs for the price. Only problem is the amp is trash I think its too weak for these subs I bought a 1200w jackhammer mono amp and hook the subs up to that thing, and started setting car alarms off easily with these things. Don't sleep on the price of these things thinking that there just some cheap small time subs there still MTX, probably the best brand in car audio.
