Changing the stock speakers on the 97 TJ with these was super easy. Required less than 40 mins to get both sides done. I had formed to drill me wholes... Nevertheless self tapping screws made the job super easy. Requirements is merely plain amazing. A huge step up from the factory setup. The highs and lows are redraw clear. Lows are good. I run the jeep with a motorcycle by top... So interstate speeds (65mph +) do often drown out the lows.. Mids n altitudes still break through though? Being able to in order to direction of the tweeters is ultra helpful. Overall I'll buy again n recommend these to friends in a heart beat.
