Hi! I am doing 240l (8,5ft^3) bandbass enclosure and I need a good amp with at least 600WRMS @4 Ohm of power from it. It should contain 4th order active crossover and eq would be a good plus.

Where could I find a good one with reasonable price?

Ps. When I started my hifi "carreer" I had had my first paycheck from my first summerjob and I was going to HifiStudio 17 to buy Jbl or Infinity speakers and some amp (because my friend told me those are good brands). When I was walking down the street I started to hear some AMAZING ULTRA LOW _BASS_.
I was wandering what on earth could produce so MAGNIFICENT sounds of euforia. Sound came bigger as we walked towards the studio (I had a friend with me), and I was more and more excited and there they were, two Jbl and one Infinity presentation car.

I told this, so you would know, that I probably won't by a nonHarman product
