I got an LC2i and a separate 100W amp to power my 8" subwoofer. Feeds clean lows. I still have to be careful not to over-power the small subwoofer.

My system is not the hard thumping rattle the windows type, but that is not what I was after.

X2 on the LC2i. You tap into the rear speaker wires for the signal, pull power from the batter in the trunk, and plug the rca outputs on the LC2i to the inputs on your small aftermarket amp and you're in business.

Even with the 6 speaker system the 8" sub pre wired is a good hookup?

So my understanding is you just bought and LC2i and an amp along with an 8" speaker and that's it...:hippy:

Personally I chose to do a 12" in a ported box, as the open air infinite baffle type of mount which is the stock rear deck location isn't ideal in a lot of ways. However, it certainly works and people do go that route for a very simple and unobtrusive install. Regardless, it is the same principle - rear speaker wires to LC2i, LC2i to aftermarket amp, aftermarket amp to sub. Pretty simple.

My problem is air bags, I have a tank and compressor in my trunk so I wanted to use the rear deck. I wouldn't have much space with subs in a box and tank back there.

Makes sense. Try to find 8" subs which are identified as free air or infinite baffle. The nice thing is the 8" hole is already there in the rear deck (just covered with a sticky sheet of sound deadener material) even if the car didn't come with the sub, so it's pretty simple to add one. This is not my area of expertise so someone else may chime in with recommendations or you may be able to find threads with more detail.
