Question about Jl Audio 12W7 Car Subwoofer

1 Answer

What to do

I currently have (2) 10W7 in a ported box and a 1000 watt mono JL Audio amp. I miss the low's I can only get with 12" speakers but am running out of trunk space.
A technician suggested I go with 1 sealed box with 1 10W7 and a 500 watt amp and a 1 12W7 ported box with a 1000 watt JL amp. No additional trunk space will be needed.
I listen to smooth Jazz and really miss the low rumble I use to get with 12's but I have never mixed a sealed and ported box like this with two different size speakers and mono amps of different watts.
The technician says he guarantees I'll be happy but this is new territory for me.
Should I just go with two 12's with 2 1000 watt amps to play it safe or has this been proven to be a winning combination.
I think he wants to seal the box with the 10W7 to keep the size of the box smaller but with only a 500 watt amp won’t it be overshadowed by the 12W7 driver with a 1000 watt amp. What would this sound like and will it give me lower frequencies without sounding all muddy.

Thanks

    Since I already have (2) 10W7's in a ported box I was planning on using one and buying (1) 12W7. The installer would then rebuild a sealed box for the 10 and a ported box for the 12. or my second option was to simply buy 2 12W7's, have him build a ported box for them and sell the 10"s. My issue was not wanting to give up what little trunk space I have left.

    Are you planning on buying more speakers, or do you already have the 10 and the 12?

Well i don't know your budget, but if that's not really and issue, right now at best buy, alpine type E, 10" subs, peak is 750w and rms is 250w, each is 129.99. Alpine type R, 10" subs, peak is 1500w and rms is 500w, each is 199.99. These are the best subs i found at best buy. You could sell your current subwoofers and purchase those, and you'd save space and still get the lows you want. Goodluck

Which amp goes with 2 jl audio w3v3 4 ohm


Choosing a amp isn't always easy but it first begins with what you want.

--RMS of the speakers is what you want to use to find your amp.
That's going to tell you what watt's your speakers can REALLY handle @ 4 ohms.
--Also what you want to spend $$$ will determine how clear it sounds.
--I prefer a Rockford Fosgate amp for base and kenwood for highs.
--Also look at the RMS watt's rating to find the proper power and go a bit beyond what you want so that the amp performs with ease.
--Last but not least you chose the amp for how many speakers you are going to connect to that amp. For example if you are using 2 JL audio 12" for subs, then a mono amp is perfect. But if you are connecting 4 speakers, you should begin to find the amp with four channels so that you obtain left, right , front and rear sound.

Try to install 3 12w3d6 subwoofers connecting 3 sub together to put them in box


You need to wire them according to the limitations of your amp you can pull a 1 ohm overall load just by connecting all of your coils in parallel- or you can get an overall load of 4 ohms by wiring each sub individually in a series configuration which will yield a 12 ohm load per sub -and then wire the 3 sets in parallel which will bring your ohms back down to 4. You can do a lot with that many coils it depends on your amp really-ideally a 1 ohm stable class d mono amp that is 1000-1500 watts rms would knock the **** outta those things JL is the good stuff.

Trying to find out wat the watts are on a jlw3 12 and a jlw0 12


The JL 12W0 needs 125 watts RMS. Sealed box it needs 1.5 cubic feet. Ported it needs 2.5 cubic feet.
The JL 12W3 needs 300 watts RMS. Sealed box it needs 1.25 cubic feet. Ported it needs 1.75 cubic feet. I wouldn't suggest running these subs together.
