Way better than stock...but....
These were a great improvement over stock speakers in my 2002 Ford F150 Harley Davidson Edit. (Crewcab). However, I do occasionally listen to music at what some people would consider insane volume levels, and at some point right before "wow, thats loud" these speakers start to distort a bit and cancel out the low/mid bass...which, I guess you can expect from speakers that cost this much. If youre an audiophile and like to listen to music loud, Id pass on these and get something else. But if youre an average joe who just wants a pair of speakers that will outperform your stock speakers (in mids and highs at least) then you really cant beat these for the price.
Pros: Cheap price, excellent mids and highs
Cons: Bass quality goes down the higher you turn them up.
