JL 13w7 and Kenwood Excelon KAC-X811D

Do you think im underpowering my W7 I def think it could be a lot louder than it is right now because right now I think my 2 15w3's on this same amp were louder. Im getting about 12.2-12.5 volts. I have 2 farad Cap. My sub is wired in Series so its at about a 3 ohm load. Heres the specs I gathered on my amp

Those specs you gave arent correct.

How much power are you going to be giving it?

yeah you're under powering it. Wire it in parallel for 1.5 ohms. That amp should be ok with it after box rise.

I had it in parallel before and the box made this "popping" sound. But I didn't have polyfill in it at the time. If I wire it in Parelle wont it be going to .75 ohms? The sub is 1.5 ohms I believe, 3 ohms in series, 1.5 ohms in parallel. I could be wrong with that though

As for the ratings on the amp, they are just what I copied from one of the websites that was selling the amp.. I don't exactly know what the ratings for the amp are thats the main problem.

533 by 1 at 4 ohms and 919 by 1 at 1 ohm are the ratings from the box. But what are the ratings for in between. Like at 3 ohms which it is currently wired.

oh yeah... I forgot what driver you had. I thought it was dual 3 not dual 1.5

uhh.. buy a new amp.

Where on the box are you reading that?

Kenwood's given specs on that amp are as follows:

533w X 1 @ 4 ohms

919w X 1 @ 2 ohms

1016w X 1 @ 1 ohm (the preceding ratings are all at 14.4vdc input)

Yea my bad, thats what they are, I must have hit the 1 instead of the 2. So what do you guys think? Do you think my amp can handle the .75 ohm load? If I do run that is it safe for the sub? will it be putting out too much? I shouldn't think that it could put out too much. also, I am def not getting the 14.4 volts. I would say on average the Volt rating on my amp is generally saying 12.2-12.5 V constant.
