New system but...

Well I got everything installed today using 3 jl audio 10w6's running off a rockford fosgate 800a2. Sounds good for spl, but I'm looking for more strong sound quality than boom boom. This is the complete lineup:
-Alpine 9856 Head unit.
-JL Audio XR525-CXi 5.25" Coaxials in the front doors and rear hatch.
-Infinity KAPPA32.7CF 3.5" Coaxials in the factory dash location.
-(3x) JL Audio 10w6 running in a parallel/ series configuration to produce a 4ohm load.
-Rockford Fosgate 800a2 bridged running @ 4ohm.

I'm wanting to know if anyone has the specs for a good SQ enclosure for this setup. Right now they are in a 3.5 cubic foot enclosure ported and tuned to 26hz.
 
JLw6's are nice ass speakers. 3 10's would blow the windows off if you gave them all the juice they wanted. I doubt your going to get very much help with speakers here. Maybe the JU audio forum?
 
Id say you can run more of a dynamic low range with a sealed enclosure.
JLs website will give you the cubic foot measurements that the W6s like.

Build a shallow top firing sealed box and take the time to tune it and youll be alot happier.

I assume you want more low end midrange?
Might want to make sure that all your speakers are phased correctly, and also run your JLs at 8 ohms or higher.
If thats not good enough do a search for low/mid drivers and find a place to put a 6-8" mid-bass......
One more strong word of advise...ELECTRONIC X-OVER
 
Well since they are dual 6ohm coils, I am running them in series/ parallel producing a 4ohm load to the amp that is rated ay 980watts RMS@ 4ohms plus if you know anything abou tthe old punch amps you know that they are VERY underrated.

actually 3.5 cuft sounds about right for a SEALED enclosure. fi you menat 3.5 cuft fo the whole thing.

I htohgth ( and my memory is fuzzy) tha the 10w6 like about a 1 cuft. so 3 cuft is about right for 3 of them add in the displacement of the driver and I bet you are just about right. so plug up that port and see how it sounds. you wont hurt any thing.
 
3.5 cu. ft. sounds large for a sealed, sounds more like a ported size.

Sealed, I'd expect the woofers to need no more than 1.5 cu. ft./driver, if not 1.0 cu. ft.

Wire them up all in parallel. Install a computer fan (lo and behold, they're 12VDC also) blowing along the heat sink fins. The the speakers in a sealed enclosure - you'll get louder, kickier, tighter bass than what you've got now.

JL, by the way, is fairly notorious for underrating their speakers, as did Fosgate with their old amps.

Run a 1ohm load on a briged 800a2? I'm not looking to start a fire in the back of my truck.
 
For the 10W6 sealed optimal volume is 0.625Cube per driver, and then add 0.06 FT3 per diver for displacement. You need a box with 2.055 FT3 internal volume.

I would suggest going with a sealed enclosure. But if you want to keep it ported that’s up to you. Either way you don’t have close to enough Mid’s and Highs to compete with the JL’s. it sounds like your running the coaxial off deck power. That’s not enough either.

Get ride of the coax speakers and go with separates and Amp them.


For the front you probable need a 6” driver in the door, a 4” driver in the kick panel and the tweets in the top of the door or the A-pillar, you can put them in the Kick with the 4” or I have even put them in the Factor 3” location and fired them up. Staging was low but not too bad.
You have Great subs don’t piss out on the mids. Stick with a good brand Focal, B&W, Diamond, JL, Eclipse, Boston Acoustic Pro series. You’ll need to amp these so pick up a good amp as well, you can stick with Rockford for there SQ is not great. Most amps these days have a built in crossover, for good sound quality equalization is very important anywhere from 6 to 30 bands will help you tune your system, you can pick up a good crossover with some equalization built in. Audio control EQT or DEQT, Rockford symmetry.

Junk the rears or keep them that’s up to you but they are worthless except to make noise. If you wanted you could do a Full range rear 6 or 8” driver but to keep SQ you will need to create some spatial restoration for the entire system using time delay. To do this you need a processor to create the delay.

Base is cheep, sound quality will cost ya.
