This is a very well made sub and sounds great, but for the price I would not recommend it. If you are looking for an extremely loud sub with super great sound, this sub is not for you. I recommend getting a hifonics OLM1600D2 with a 2000w RMS amp at 1ohm. I had the earthquake in for a while but couldn't stand that it wasn't that loud so I put my Olympus back in(olm1600d2).
