I don't like/trust power acoustic, i would go with 2 kicker cvr's on that budget it would prolly be like 180 shipped off of ebay, they only push 400 apiece but i bet they would sound way way better IMO.
And from what i hear they are sh.it^^^^^^^^^^ Those premier subs are like having a car with a 454ci engine but no discplacment. Meaning an amp with 3000 watts of power could be more efficiant in supplying sq or spl to a sub of less power in doing so also sound better and be louder. Take the extra $ you will have to spend on the 3000 watt amp and get a two eclipse ti's, 600 watt rms and a kicker or orion 1200 and your system would souund better for less money and less power.
oh yea i just learned to go with the crytal pro subs that are like 170 or somthing. Supposedly they have more sq and get louder then the type-r's. But def don't go with pioneer premeir. Are you looking for sq or spl.
