I bought a 15" Fi Bl which is going to be powered by a Jl 1000.1 wired at 4ohms (JL 1000.1 1-4ohm = 1000watts) I'm running 2 awg wiring right now and I'm going to move up to 0awg(proboly best right?). I also am running a Kinetik HC1200. I am planning on doing the big 3, also I just have a stock alt, think it will hold up to 1000 rms? Or should I upgrade? Is 16v nessecsary or 12v battery?

Now on to the box idea!

Heres my design so far, it's a dual L port box...and heres the specs...

5.3 cubes
35hz
Square port area = 112
Square port volume displaced = 4213

Does that sound like good specs?

Or should the box be smaller and tuned a little lower? One thing I never knew was, is bigger better?

That amp is regulated, it will do 1000w at any voltage down to 11v.

2 awg wire is fine for the amp. 0 awg should be used for big 3 butyou could get away with 2

for only 1k watts 2awg and that battery should be fine.
is this going in a car , truck, in a trunk?
how the sub and ports face are also important

a car trunk. It's all facing the rear of the vehicle. It's gunna be a double L-port box, with a port area of 108.5 which is like more than enough.

get the 16v system out of your head, you would need a 2nd alt, ect..

I had the JL 1000/1 at one point and while I really like the amp I can tell you that efficiency is not its strong point. I replaced an Alpine MRP-M1000 with a JL 1000/1 (not v2) and while my stock alt could keep up with the Alpine, the JL set to normal gain levels at moderate to high listening levels would pull so much my headlights would dim considerably. I don't know about the specific efficiency for it, but I remember reading a bench test where the 500/1 was only hitting in the low 50% range which for a Mono D amp is not so great. I would say you really should consider a new alternator with that amp. It is a sweet sounding amp, but it is also the reason that made me finally need to get a new alternator to keep up with it.

That is true, they are not efficient at all.


" get the 16v system out of your head, you would need a 2nd alt, ect.. "

I've been trying to get him to forget it everytime he brings it up haha.
