So I got my Infinity 1262W 12" sub installed two weeks ago and I've had time to dial it in. I wired it for 2 ohms with 8 gauge wire I had laying around. I silver soldered the wires to the tabs while compressing the wire in place with pliers to make sure i got a good strong joint.
I put them in a ported enclosure I got free from the neighbor that is 1.5 cubic feet so it's .25 cubes too big and infinity recommends a sealed box. I had some reservations. I'm powering it with a Soundstream Rub 1.400.
My impression so far is that I'm getting nice tight bass where I want it with some boom thrown in on certain recordings. I wish different recordings weren't so far apart on the low end. I could just about adjust for 70% of what I have on my thumb drive if I wasn't training myself to put up with the changes between recordings. Mostly I wish some of the older rock recordings bottomed out a bit lower.
Anyway, for what I listen to (classic rock, lots of alternative, blues and some country) it fits my needs nicely.
For $50 shipped you can't do much better.
