Dissapointment with JL subs
As you guys already know i have 2 10" JL 10W6's and an Alpine 9814. I am using a JBL 600.1 as i was recommended to do and have infinity 6402cfp up front with pioneer 6x9's in the back in boxes.
With this setup i thought i would be able to have my subs loud enough to stop your heart sort of thing but they are nowhere close to that. you can hear the bass but you cant feel it. i tried turning up my gain to full but then the subs start to distort.
What can i do?

Re: Dissapointment with JL subs (KDuniverse)
Something must be wrong, maybe with the setup, wiring, etc. I have 1 JL 10" and you can feel it through your bones
I have friends who have put together systems that pound more than this with pyramid subs and amps.

... What impedance are the drivers? How much airspace is in your enclosure?
...are your ohms correct? Enough air volume? parallel or series correct? Is your enclosure sealed correctly? I have one 10" now and it pounds clean for a single 10"

This may sound silly, but is there any chance in the world you have the speakers wired out of phase? Disconnect one speaker and play the music, if it's louder than before, reverse the wires on just one of the speakers.
We used to play this joke on unsuspecting victims... I almost got an entire sub setup real cheap!

Re: Dissapointment with JL subs (Conquer)
dont those subs perform best with about 600 each? Yeah, what size enclosure? its ALL in the install. What way are they facing? Crossover point?

I agree, 600 watts isn't enough.

Have you checked to make sure the speakers are in phase? Having one with +/- wired backwards can really kill the sound.

Re: Dissapointment with JL subs (battsup)
The box is polyfilled and i sealed it all with silicone. I know the potential is there because when i first put them in they would blow out little shards of polyfill.

Re: Dissapointment with JL subs (leolufse)
ok so i disconnected the drivers side and was able to change the settings to get way more pounding out of the one sub. But when i connected it back up it was distorting a high volumes(driver side) so i switched the polarities and that made it worse. my box is the same as those boxes you buy at walmart, you know the ones with the 2 10s and 2 tweeters for 30 bux. Do you think my driver side sub is shot?

What are the ohm load of your subs?
What is the size of the walmart box? Are there still other drivers in the box?

10w6 require .8 cubes each. Make sure your box is wired in phase. I would have to agree that you should throw more power at them. I have a 500/1 powering my 10w6's and it hit 141 db at the last db drag race.

Re: Dissapointment with JL subs (battsup)
alrite then i am gonna need a larger box, my current one is .46 cubes per side and is ported. Also my amp is 600 watts RMS why do you say that is not enough?(I have everything wired in parallel so the resistance is 1.5 ohms)
that's way to small... ported boxes are bigger than sealed, so that's crazy small!! also is it "ported" or does it just have a big hole in the box?600watts is plenty, i'm running 500watts to 2 subs and hey hit like crazy.

Re: Dissapointment with JL subs (Kale)
the box is way wrong.
If you are not fimiliar with woodworking, go to an stereo install shop and they'll hook you up but it will cost more than $30. You can run them together in the new box that has an internal volume of 1.5 to 2 cubic feet sealed. They should use 3/4 MDF wood. I bet that box you got from Wally World is 1/2 particle board
Keep us posted
PS If you keep running the JLs in that small ported box and crank it up you got a very good chance of blowing the JLs up since they will not be loaded correctly below whatever the tuning frequency of the ports are. That that small of box and ports, that freq is WAY too high
