What voltage to set gains on Kicker kx2500?

[BobbyDD 10+ year member]

I have the amp pushing a HD315. I've read the entire sticky on setting gains and set it at 70 volts after following the instructions on the tutorial. It didn't take long for the sub to start stinking. Is 70 volts too high?

In my opinion, yes its a lil too high.. I'd run it around 54 volts which is 1500 rms, that should be good for music. Assuming you have it set up for music

Yea, it's just for music. I just read where almost everyone says to give them 2000-3000 watts so I thought I'd try it. Even DJ at AQ says they can take 2500 with no problems but the sub sure started stinking in a hurry.

Yeah, i hear ya but I'd start there and break the sub in for a lil while and then later if you want you can crank up the gain to the 2500 rms

You're probably right. Thanks man.

Well, I hate to admit it, but I blew my sub right before I started this thread. It's fixed now and I want to make sure I don't do it again. Cass from AQ said it had been clipped badly. He suggested an extra battery to help prevent voltage drops which I have on the way. I went ahead and tried to set the gains today at 55 volts which should be about 1500 watts at 2 ohms. The problem is with the bass boost off I have to turn the gain about halfway before I can even get that much out of it. I know everyone says bass boost is the devil but if I turn it on about a quarter of the way I just have to turn the gain barely past a quarter to get 55 volts. In order to get 70 volts which my amp should be capable of doing my gain would have to be about three quarters without bass boost. I want to get the most I can out of my set-up but I don't want to blow anymore subs. I have a 200 amp alt, big 3, with 1/0 gauge throughout. When I blew the sub before, the bass boost was completely off but I had to set my gains very high. Has anybody ever had this problem with the kx2500? Any other advice?

p.s. I searched the forums for about 3 hours before this post but I still am confused on what to do.
