Well I want to change around my sub set up. Right now I am running Two Infinity 1250W subs, on a Kenwood KAC-9102D Amp.
Now, it is good, but for the size of my car, and always wanting more, I want to upgrade.
I have Two Kenwood KAC-9102D amps.
Should I eather buy 2 more Infinity subs. Basically just double the setup I have now. Downside is that I will have to buy or make another box to fit them all.

Or, buy 2 new 12'' subs, aprox 1000w rms each, 2000w max. No need to change my box, if they will fit.
If so, what kind of subs do you people recomend. The box I am running now is aprox 3ish cubic feet.

 

That amp says it does 850 wrms@ 2 ohm.
So, if it was my choice, I'd put one sub on each amp, then it would pound!!

And, If I had my choice of subs, on the very limited budget that I have, I'd go with Kicker. I've had apline & pioneer before, but I really like my Kickers.

So, you want to stick with 12" and use the same box? Can you cut out the box to fit solo-barics?

Here is a link to the 06 S12L7 4-ohm 06S12L7 Dual coil means they'll be 2 ohm total each. Rated 750rms, I think they'd be perfect.

Thanks Tom.
Am I able to cut my 12'' holes in my box, to fit Kickers ?

Also. I was looking at these subs, they are going for real cheep on ebay aswell.
The JL 13.5 W7 subs.

Only problem, I can't find the specs for that sub.
I thought I read somewhere 1000w rms...

 

Are you running a sealed box? If so I would try a ported box before blowing $$$ on more or different gear.

 

^^^^^^ Ditto that.
