Dont worry these Alpines just dont cut it. I have had them less than two months and blew one last night listening to rock music lol. Gain set the right way and the crossover set to what Alpine says they will take on the low end, with a 4 channel amp putting out exactly 100 watts RMS to each. Bass on Deck set low and they still crapped out. If you want an overgrown tweeter these will work lol. Not a good mid at all. A 50 dollar set of Pioneers has more bass and DB. Major let down. Alpine will be getting these back.
