I Finnally figured out what i want (i hope, i do change my mind a lot :-(). I am going to get a 12w7 here soon with an H.O. box. I've read all the posts, and i know Glass recommends a JL 500.1 for one w7. Here's the problem, i plan on getting another one in the next 2 months or so. I would rather stick with matching them and get a JL amp. If i do decide to get another, should i just get two 500.1's and buy just one now (and the other later) or should i go with a 1000.1 ($$$:-()? I was also thinking about a JBL 1200.1 that i could get for very cheap. Just hoping to get some suggestions thanks a lot guys. (PS for all i know, ill change my mind by the morning and decide to go with a different JL. IT IS JL FOR SURE THOUGH)

thanks a lot guys

The 12W7 takes 750W RMS. So, if you ABSOLUTELY plan to get another one, I'd go ahead and get a 1000/1 amplifier and be careful with it with the sub. It'll be cheaper than getting 2 500/1 amps and save more space. Turn the sub level down on the head unit or something of that nature, if you run them on rear speaker preouts you could fade them out. If you have the money, get the W7, I wouldn't recommend a different JL unless you go the single 13W7 route with a 1000/1 (which won't hit as hard as the two 12s, SQ will be similar). A JBL 1200.1 would work, but I would get the JL amp for sound quality purposes, also with the H.O. box you'll need to set the infrasonic filter (which the JBL 1200.1 doesn't have).

well this is just me but i wouldnt run the first sub until you have both so that you have abtter chance of them both lasting the same amount of time. And that way you can break them in at the same time also rather han breaking one in and getting used to it being loud then having to turn it down again

Yeah you're right jon... the deal is i like to buy my stuff off ebay, and i can get the 1 12w7 and a high output box for around 300 not shipped... it's used a little (so he claims) but that seems like such a good deal, but by the end of the summer i am hoping to customize the whole back of my jeep the way i like, with 2 w7's so room doesnt seem to be a problem (once i get rid of the H.O. box and go custom) Should i jump on that deal? Or wait till the end of the summer and buy everything at the same time... i can probably get 2 500.1 for the same price as a 1000.1 on ebay, just i could get one 500 now just to have one in my car... let me know your opinion :-)

thanks so much guys!

Good deal if it's in good shape. You could get two 500/1's, but you'll need a distribution block and run 2 guage preferably to that. The benefit of two 500/1 over a 1000/1 is that the amps will both see a 3 ohm load instead of the 1000/1 being pushed pretty far with the 1.5 ohm load. You'll have more headroom and better SQ, and less heat from each amp. I wouldn't run a 12W7 an exceptionally long time off a 1000/1, but as long as you don't push it too hard it'll be o.k. JL is conservative with their ratings. You might as well get the H.O box and save the money on the sub instead of paying 400 new. You may be happy enough as it is with 1 12W7 in the H.O. enclosure, great SQ and a lot of SPL for one sub, you may not even want two. If you plan to run it for a couple months, just get the 500/1.

I agree, i sent an email to him hoping for the truth on the condition etc. Hell it may be enough, but who knows. I can hook everything up and then in the next 2 months we will see where my plan on the whole custom trunk thing is. If i get a good response from him, ill go ahead and get that and hook it up to 1 500.1, thanks a lot man, couldnt make decisions with out ya!

thanks again!

k i ordered the 1 w7 in the H.O. box, now im going to get a 500.1 like you said jon, but a guy at the local JL dealer recommended I should get the JL amp kit. Should i JL get or spend less money and just get a regular 4 ga. from knukonceptz.com. Btw, is it possible to hook up 2 amps, to one amp kit so i dont have to buy another later on down the road? ( JL does sell a amp kit for 2 amps)

Thanks again!

no you wont need a new amp kit. you will need 1 power dist block. some 8 gauge wire. and a new pair of RCA cables. thats it

okay thanks, so should i go ahead and have the guy order me a JL amp kit, or just buy one from knukonceptz.com. Or is it possible to use my old kit for my 311D, i believe its 4 gage, I have RCA's and all the other stuff, but i dont know if its up to par with the JL im getting. Thanks again man!

On that jl sub can you wire it at 2 ohms.

Chris if you already have a 4 gauge kit use it. Don't pay all that money for that JL kit it will be the same as the one from knukonceptz just in a different package. Good Luck with that 12W7

Also to Davids no you can't wire that sub to 2ohms cause it is a SVC with 3ohm voice coil.

So im guessing you can wire it to 3 ohms then. If thats the case take a look at the xtant A6001T on ebay. It will proably put out as much wattage as the jl 500.1 and be about half the price. It puts out 600 at 2 ohms and 300 at 2 ohms so proably about 450 at 3 ohms. Almost as much as the jl audio. Also it will put out the same wattage no matter what the voltage is.

Get the 4 gauge kit from www.knukonceptz.com. It will cost you about 38.00 shipped. It will take about 3-4 days at most and is very high quality.

Alrighty, i just got my one 12w7 in the JL H.O. Box and it looks awsome! (thing is huge) Now i am just waiting for my next paycheck to go and gobble up a 500.1 like you guys said. Then ill get the knukonceptz 4 gauge like u said david. But last night I came across this

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=5710459735&ssPageName=ST RK:MEWA:IT

I'ts the new JBL GTO1201.1 amp that replaced the BP1200.1. It is rated at 787 watts RMS x 1 @ 4 ohms. And its a lot cheaper then a used 500.1. Now to my thinking is, the JL runs 500 at 3 ohms, and this spits out 787 at 4 ohms and its cheaper? So i'm thinking this a good choice my sub is rated at 750 rms. 787 might be pushing it a little but not to much? Let me know jon what you think... maybe there is something i dont know or whatever, but thanks again, cant wait to get this bad boy hooked up!

The JL amps put out closer to 650-700 watts RMS, they're severely underrated. You have to remember that the JL sub is 3 ohms, with the JBL running a 3 ohm load the power will be in the 900+ range. You'll have to be very careful not to push the sub too hard. The JL amp will have better sound quality than the JBL, won't overpower it, and has more features such as an infrasonic filter, which you need with the H.O box.

well I would be ordering my amp this thursday, but i had an unexpected turn of events yesterday. I totaled my car :-, i was lucky to walk out alive, let alone with no injuries on anyone in the car (thank you Mr. seatbelt). So i have to put everything on hold. Thank god i had not put my w7 in the car yet. I am going to be taking out a loan, and will be buying a new car soon (most likely an explorer or a blazer) So I'll have to wait until i get the car and then put some money away for the amp. So you know what that means, a bigger car = more trunk space :-). Don't really know why im posting this, but I thought id post justbecause i wont be able to update with progess. I'll put some pictures up of my wrecked car once they develop. Wish me luck on buying a new car (anyone have an explorer/blazer/jimmy and love it?) let me know, thanks!
