I have a 12w7 in a ported box 1.75ft^2 @32hz. I am pushing it with an orion 1200d. so at 3ohms its prob getting 500-600w. it just doesnt seem loud compared to other setups I have had.I can turn the gain up and it is closer to where I think it should be but it is distorting? do I need to suck it up and buy a new amp?

Yes. That amp is under powering that sub. You wont see the full potential out of it until it gets ~1000 watts.

im no expert on that sub but generally speaking thats cuft is kinda small for a 12" ,typical 12" is normally in a 2-2.5cuft sometimes more depending on what ur after ...but i suspect ur box maybe the problem here .....

Its in a toyota celica...well I had a bigger box designed...until I posted on here and was told that it needed to be smaller...would it be a good idea to get another 1200d and bridge them? Or should I buy a new amp?

just get a new amp. my friend put a kicker zx1500.1 on that thing and it sounds awesome. the zx1500.1 does 1500wrms at 2 ohms so it will still put out good power at 3ohms.

David, it's all in the box design with 12W7.
And yes, the HO box is quite big. For everyday use, I'd recommand 10W7 in a HO box. That sub with your amp should work well.

I would get a Hifonix Brutus 2000w class d amp it's around 600 bucks takes a beating and hits hard. make sure you have a cap.,at least 4 guage wire, and get the right box custom made for your car. also if you are using a factory head unit it will greatly decrease the performance of the sub and amp...you need a good min 4v output headunit also if you want to keep the factory unit there are kits out there that amplify the output voltage.

well the amp is very efficient and all but I have it on a 2 farad cap anyway. I wasn't really a hifonix fan whatsoever but I was pleased with the brutus 2000w I'm sure there are cheaper amps out there too..ie ebay and whatever...i'm just trying to help.

elp is always appreciated.

people on this forum are not really fans of capacitiors, just so ya know...

also you will be introduced to many brands of amps that you have never heard of before


but everyone is a noob at one point on ecoustics!

ok so, the only advise I have gotten so far is a Hifonix Brutus and a kicker zx1500.1

Is my best bet to go with the jl 1000/1
I have heard a 12w7 on an jl 500/1 and it was A LOT louder than my setup...

before this sub I had a re xxx which the tensils on the hot side broke.

So Basically here are my options.
1.) Get a new amp for the W7 ($600 ish)
2.) Get the xxx reconed (have a quote from fi audio to do the recone.)($180 after shipping)
3.) get another 1200d and bridge them together. ($150 used on e-bay)
here is the box I built...its actually 2.15 ft^3 tuned to approx 31.25hz
box is made of mdf with an oak veneer. My dad owns a millwork company so this was just some scrap wood.

I'd get JL/1000 amp for your 12W7 sub, end of story/problem.
You have a quality sub, so purchase an amp that's of equal quality, not less (Hifonics).

A 500/1 will be underpowering slightly but it will still sound decent, although the 500/1 is better suited to the 10w7, the 1000/1 more for the 12 and 13. If I were you, i'd get a 1000/1 and if you have the space, you could go slightly bigger on the box.

if your sub is getting 600 watts, and you heard the same sub on a 500/1 get louder, then it is your box.....

The box is built exactly to the drawing above. As I said before my dad owns a woodshop and I had a professional build the box. There isn't a 1/32" difference from the above drawing. If someone could check the tuning that would be awesome.

I do think that it is the amp. I do not know for sure how much power the sub is getting or even how to measure the output of the amp.
If I turn the gain up it gets loud but starts to distort.

well i dont really like jl myself, everyone else loves them so they must be pretty good, the thing is people say theyre spl subs, but i dont really hear them that way.

buy another amp, also make sure that your wiring is correct, because it sounds maybe that your ohms are off

get a hifonics 1606 brutus, mono block, at 2 ohms you would get about 1100 watts maybe, on ebay brand new they run about 230 - 250

the amp is stable down to 1 ohm. The sub is a single voice coil. So I'm going to disregard those two posts...

Project Pat the W7 are sql sub not spl subs. Two don't go with hifonics. I agree with isaac\rovin JL 1000\1 end of story.
