Hey guys title says it all just purchased two JL W3's 12" and now I need a box. Im really not sure what specs i need for the box, but I know that I am wanting to get ported cause I listen to alot of rap and dont want sealed. The subs put out 500 RMS each and are 4-ohm subs. Please help!
Thanks!

Look in the owner's manual in the box. It specifies the size of boxes for you, and gives all the pertinent information. Or you can look on the JL site. Do some digging for yourself, mang.

How do you know you want ported? Based on your listening, or what others tell you? And subs do not "put out 500 RMS." Amplifiers "put out" power, subs take it in.

270 up to 300 rms each.
Just get a 500/1v2 to push both and it'll sound great
Dont get the premade ones they suck

i would get a sealed box especially for the w3. i ran the w3 with a ported box before and it sounded okay....the seal will still hit hard but nice clean and tight.

Ooo haha didnt know that but i heard that for a lot of people that listen to rap ported is the best option

Boomin

S Q = seal box
Loud = port

Hope this helps

2 12's with 500 watt amp is very loud no matter what you do

It can be a good option, but if you find yourself reaching for the volume button when you're already hitting it fairly hard, a vented enclosure can be more dangerous for your subs because if they unload below the tuning frequency, they're done. If you go vented, I highly recommend that you get with an experienced box builder, tune it a bit lower than what is recommended, and understand that it will be even larger than the recommendation of JL, which is already a good bit bigger than sealed.

As Boomin said, 2 12's on 500 watts is going to be very loud no matter what. I like the fact that a sealed box will go lower and with better extension than vented. The tradeoff is those last 3 dB's of output. I'm willing to trade them in.

Yes I brewed if you go with sealed you are stuck at a certain db Point but with porter you can tune it to whatever since there's a port, I will go sealed if that the best option for me or if you (Big Mack) reccomend that to me haha.

500/1 and a sealed.
I'm running mine with a 500/1 and I think it's perfect.
I can say from experience that ported are definitely louder than sealed, but sealed is tighter and sounds better. That's why I'd just go Sealed>Ported. Especially if this is going in the trunk of your GS.

what would you guys recommend for an sc300? sealed or ported? because the trunk isnt right next to the cabin. there is a gas tank with open area before the cabin so i might need those extra 3db. :]

I dont know Mr. Mac... I'm running 2 12's with 1000 going to both of them and its not loud enough

Sheehan1p

yes haha this is going in my trunk

Do you have JL's?

Mr Jokster

Currently no, but I was running 2 13w7's with a JL 1000 to each (before they got stolen ) still not enough

Just do what big mack said in regards to tuning low, you'll be fine.

Hell, if you want, I'll send you the specs to my box and save you some time
