JL Auido W4

I hope this isn't in the wrong board. anyway, I installed tow jl audio 15's (2ohm dvc) I think they are w4's. The recommended air space is 2.25 ft^3 and 200 watts rms. Is this 200 watts per coil or woofer?

I hope it is woofer.

I went with the recommeded specs with a rockford 801s (2x200 rms @ 4ohm) and 2.25 ft^3. The woofers are not very loud and do not have that hard hitting bass like I know they should. you can't even feel them in the air. Also, they pop when you turn the radio up. But even here, they aren't that loud.

I think the box is too small, am I right or wrong? What should be My next step.

p.s. I tested the woofers and each v.c. resists at ~2.4 ohms

Um, first of all I dont think JL Audio has ever made a W4 woofer....although I could be wrong. Second, the box isnt too big but maybe it has an air leak. The popping sound isnt normal and may be a problem with the sub, and turn up your gains on the amp so that it gets louder. Plus with 400 watts I dont know what kinda bass your expecting....it shouldnt be too loud

Did you build that exact box?

You need two ports 3" by 11.2" internal dimensions, and 2.25 cubic feet after all displacements...

Those power ratings are total, thus 100w rms per voice coil

Um, he has a sealed box, thus there shouldnt be any ports....

If they are popping, are the bottoming out? Or mabey the tinsel leads(sp?) are getting a bad connection? Do the woofers move violently when the pop?
