[major editing - after more research, i've smartened up my post.] Hey guys, I am new to the forum, have been reading things over for the past few days. I am starting work on a home theatre. I have a pair of Infinity Alpha 20's that I picked up, and am starting to design the amplifier side of things. I have a pair of JL 10W3 car audio subwoofers that I would like to incorporate into my system. They are Dual 4ohm speakers, so I can wire one to 8ohm or 2ohm, or both to 1ohm or 4ohm. I was thinking of purchasing a mono amplifier (or bridgeable) that goes to 4 ohms and just pushing both of them. A higher output amp at 8 ohm would probably be more expensive, and would probably handle a 4-ohm load anyway, so why not use them both. My first question is how suitable would car subwoofers be in a home theatre setup? They have very nice excursion, and I have them each in a ported box, so I doubt I would have to make many if any adjustments. What is the difference in design between home and car audio subs, other than car audio ones tend to me more weather-friendly? I guess this would be a good time to describe my environment. It is a 11 x 15 room, with the television on the 11' wall. It is actually a college dorm room, if you wonder about why it's so small. The system will be moved to a room about 20 x 20 when I get back home. I live (go to school) in the Utica, NY area, am relatively new to the area, and have yet to find a place that sells professional level pro-audio equipment, therefore it's hard to really test and listen to the equipment. I am going to be looking around a bit more for a shop that sells what I am looking for.
