I am trying to figure out what my options are before buying anything else. I have a Silverado regular cab pickup, currently with two L7T 12" square DVC 4 ohm subs in the Kicker prefabbed boxes. (I chose these because they are the hardest hitting prefabbed that will let me put the seat ALL the way to the back. I am currently running a fosgate 1K watt amp. I chose these because the size is perfect to sit behind the seats, and the width is enough, where if I put the center seat back down, they are not visible.
I have taken some quick measurements and I believe I can fit a third enclosure back there, (will be tight, and I will either have to remove or cut the C pillar panels to make it fit). This is actually the finished product how it sits, other than I have since replaced these subs with the square ones (more power and 30% more cone area). I am currently running 3 subs with a focal 100x2 to some JL audio 4" in the C pillars, a Hertz D power 4 with 130x2 to a set of JL audio ZR 650 components in the door, and the 2 L7t 600w RMS 12" Kicker subs powered by a Fosgate P1000x2 amp, (that sits completely under the seat, and will cut out from overheating when its about 108+ degrees out with the windows down, after about an hour at full). It might not look good in the picture, but that's fully installed, and completely hidden when the seats are installed. (That junk in the middle is a board with the two distribution blocks, a relay and a busbar to wire the remote wires). It's decently loud and hits well, considering I wasn't going to compromise on the seats or my leg room.
ON TO THE QUESTIONS:
1. Just to triple check, as long as an amp can run 2 ohms, it can run at 2.7 ohms?
2. 2.7ohms is 1/3rd between 2ohm and 4ohm (where all the power settings are listed). If I put in a 3rd sub, they are rated at max of 600w RMS. I would like to get as close to that as possible. The JL audio HD amps are one of the few that run the same RMS power at 2 ohms and 4 ohms. If I want to get 1800w @ 2.7ohms, how can I get to that number? Is there a formula that would allow me to figure this out, or is it just something I would have to guess at? (I tried searching for this, and from what I gathered I would need, to know the amplifier's amperage output, and would then be able to figure the wattage). Is there any way to figure out what an amp's wattage is at 2.7ohms when nobody lists that?
