yea those pioneer premiers are pretty good, my friend had 2 of them running off a 1000 watt kenwood mono and they pounded. i do agree that sony is not the best,, since when i went to BB they had a quality chart rockford fosgate amzaing - Jbl awsome - sony good lol, so yea.... i got 5 1/4 sonys in my doors. only got them cuz they were 35$ on sale lol.. and i got the 6x9 xplods in the rear, they are not to bad. but i do realize there is better... only paid 140 for the set though so yea. the only reason i got the visonik is becuase it was brand new and the guy wanted 50$ lol for the sub box and amp..... he paid 100 for it lol.... BB has a kenwood 1200W 400 rms for 139.99, might get that mayby.... i dont got a CC right now so i cant really order off the net unless they do bank transfers.
