JL's are the best quality speaker out there in the marine industry. I work for a large boat builder and all our boats that get upgraded systems go to them, but unless you are running an amp and wan tto spend $400 a pair, they are not worth it. If you aren;t running them off an amp they will never fully reach their potential and their are cheaper speakers that will perform very close to the JL's for half the price. I will let you know how the Infinity's sound, they are 75watt rms and 225 watt peak, far more then what my reciever is putting out, and infinity speakers are always very clear and crisp and every review I read they also commecnted on good bass quality and they got very good ratings on the sites I looked on. Got them off Ebay for under $100 for the pair, could have saved another $10 on there but I went with a seller with the best rating, I'd rather buy from a guy with no problems then save $10 and take a chance with a seller who has had issues before, still cheaper then in a store.
