Car Forum / Driving, Maintenance, Tuning / Car Audio / August 2006Alumapro or JL.
Well dang I dont know where else to turn. So here I am typing. At the moment I have a pair of 10" Alumapro alchemy subs the 4ohm version. I also just purchased a pair of JL-10W6V2. I'm torn with which pair of subs to put into my Dakota R/T.. I have Focal components driven with a xtant a4004 and I plan on driving the subs with my a6006 xtant amp. I know the alumapro's will sound good because I've had them in my other vehicle for a while with an xtant a3003 amp with a mere 150watts a piece and they slammed. Is it me or is JL Just a big noise maker? I heard a 12W7 at a car shop here in philly it sounded good but it was also being driven with some zapco 1000watt monster amp.. Deep bass isnt a problem for the alumapros, I would assume with the size of the jl and its ridiculous magnet structure they make good bass too. The question at hand here is which is a better match for the Focal speakers I have. My previous vehicle i was running memphis components on a rockford head with the alumapros. The new vehicle rig is a pioneer xm head, xtant amp, focal components, alumapro 5 farad cap. if anybody has any insight on my delimah that would be great. I think the bigger question is what amp will you be using with the subs? The JL W6V2, if I recall, sound much better with more power than 150w per sub, where the Alumapro's were more designed for lower power applications. The W7 is JL's top of the line sub for people to make their penises seem larger. They are also highly over-rated and over-priced IMO. The lower models are not nearly so blatant, but will still get loud and usually sound good doing it, provided given a proper enclosure. Either sets of subs you have will sound excellent with your Focal's in the proper box (dependent on each sub of course). You may want to use WinISD to model an enclosure that will fit your needs Brandonb > Well dang I dont know where else to turn.

I'm running an Xtant A6001 for my subs its 600 watts @ 4 ohms I also have a 300 watt version of the same amp the A3001, it mated excellent with my alumapros. Hopefully it will do the same with my JLs. My enclosure is sealed the MTX 2x10 thunderform that fits under the rear seat in my dakota. I have a space issue, I need a back seat and I've modified the mtx box extensively to accept the mounting depth of the JL or the alumapro. Mtx gives you the great option of using their woofer which is craponya in my opinion or any woofer with a 5" mounting depth. At least the box is 1.8 cubic feet of volume, allowing .9 cubic foot per woofer.. I've decided to try both sets of speakers. I will run the Alumapros first then the JL. I only do it in that order because I know the JL is going to make ridiculous bass.. It boils down to me being brand loyal with Alumapro for 5 years of good service with their alchemy woofer and being afraid of JL and their instant success.. I might just stick with the alumapro so Im not like everyone else out their with a w6 and a 500/1 in their trunk.. Thanks for the help though, This has been a confusing task at hand. The local car shops here are all about Loud obnoxious bass, they wouldnt know a good system if it bit them in their a.ses... Anyone who thinks audiobahn is good stuff should be tazed several times with a cattle prod.

Hopefully it will do the same with my JLs. The impedances of the JL subwoofers are also a bit different than that of the Alumapros. The Alchemy's *should* be single 4-ohm right? As those amps are both monoblocks, wired in parallel that'll be a 2-ohm final load at 300 watts, or 600 (according to the manual for the A3001/A6001 respectively). The JLs, however, are dual-4-ohm each, which means you'll have the following final load configurations: 1-ohm, 4-ohm, 16-ohm. The manual also shows neither of those amps are 1-ohm stable. Oh, and the A6001 is 600 @ 2 ohms, and only 300 at 4 according to the manual on Xtant's site. You may have problems properly connecting the JLs. > My enclosure is sealed the MTX 2x10 thunderform that fits under the > rear seat in my dakota.

The JLs are wanting a bit more than .9 aren't they? and are you sure that's still the volume after your extensive modifications? > I've decided to try both sets of speakers.

I'm still a little concerned about the wiring of the JLs to those amps though. > It boils down to me being brand loyal with Alumapro for 5 years of good > service with their alchemy woofer and being afraid of JL and their > instant success.. JL and "instant success"? They've been around a bit longer than Alumapro. Been rather huge since the 80's at least. > I might just stick with the alumapro so Im not like everyone else out > their with a w6 and a 500/1 in their trunk.. Who cares if other people have it as long as it sounds good and works to your liking? > Thanks for the help though, This has been a confusing task at hand.

Audiobahn has its place... but not in my car :) Brandonb Hi I'm gonna ebay them this weekend. if anyone wants them $200 a piece, like new, used for 1 hour. I hooked them up. Xtant drove them fine.. TOO MUCH BASS... Way to much even with the amp gain next to nothing. I guess I just wasted $400 for nothing. And for anyones reference, the alumapro makes deeper lower more crisp bass. The JL is all about SPL, it makes so much even at low volumes that it makes a human ear tweak out and distort. Thanks for the help brandon. |
