installed 4 in my 98 mariah talari last season and very pleased. paired them with an jbl amp and the clarity/volume is very very good. i did blow 1 tweet towards the end of the seaon.[sitting still,90+heat,direct sunlight,at near full power for extended ammount of time] but that was my error.the only real problem is that the magnet housing is a bit larger than standard 6.5's,some careful dremelling might be required.but still a solid investment indeed.if i could change anything about this product,it would made in the USA!!!! [example.JL audio subs] as far as sonic electronix goes, it's a no brainer. there shipping times,and price point is spot on. thank you sonic.
