Just had these installed hooked to an Alpine KTP-445 amp in the front of my 2003 Jeep Liberty, tweets in dash, mid basses in doors. Also hooked in a 3-way set in the rear doors. These speakers are a 200% improvement over the "premium" Infinity's that were stock. The highs were crystal clear and screaming. The mid bass thumped nicely. The only con I can see is the deep bass needs a little help so I will be adding a 10" sub to round out the sound. Otherwise, I would say get them....great value for very decent sound. They match well with the amp I'm using and if they last as long as my stock speakers did, I'll be extremely happy. ;)
