I just wanted to say thanks to everyone for helping me with the questions I had about my system. I just got it done. I have a kenwood headunit with a 15w3 in a huge ported box and a Hifonics bx605 amp. I know hifonics, you guys dont like it. But this must be the right match up with the sub and the box because it slams. I wouldnt want anything louder. I have to keep the boost down to about 5dbs to be able to drive with out my ears feeling like they are going to bleed...lol... .but thanks alot guys!
Glad you like it. We don't really hate Hifonics, at least I don't. If your low on cash then it's all right to use, the amps just have some reliability issues, and they're a little overrated.
