JL Sub/box help

StormTroopin · Nov 9, 2010

Ok so I built a box a few months ago with the exact measurements to get .625 Cubic feet required for my JL 10w3v3-4 in a sealed box. The box is well sealed with wood glue, screws and extra caulking. No cracks or leaks of any kind. My problem is that whenever I go to turn in up, it pretty much falls flat on it's face. I need to figure out whether I need to make a new box, new sub or whatever. I have a suspicion my sub might be going out.

Any help would be greatly appreciated, this is not my strong suit.

sounds like your speakers are out of phase. i had that problem on mine. what amp and what ohm are you running?

A JL 250/1 amp... I'll look at the ohm rating tomorrow. The sub is a 4 ohm. That's what the 4 at the end of 10w3v3-4 according to the website.

Messing with the ohms isn't going to do much for your problem. Try changing the actual frequency with the equalizer on the amp.. if that doesn't do anything, then yeah its safe to say there's either a leak or the sub is going out.

also check your polarity, and make sure your amp isnt set on inverse

And if your gain is set too high you will start to distort as your volume increases...

I'm fairly certain it's the sub. I'll toy with it some more, but it looks like I might need a new one. Anybody got any recomendations for an under 150$ sub?

oh i thought you were running more than 1 sub. check the polarity, if that isn't it then its probably the sub.
