i had a pair of the 6.5s in the back doors of my truck in some pods. they dont like lows, id recommend crossing them at 100hz but they get loud as *uck and i fed mine 150w a piece with no problem. i dont recommend them if u are trying to do the whole time alignment,staging, and imaging thing these are made to do 1 thing get loud on a good bit of power. yes they sound great but i much rather the t3s i had in my front doors to them.
all and all i still like my memphis components against anything rockford. they may be a bit harsh sometimes but the rockford t2 tweet is ridiculously harsh, the t3 was ok and i rather liked them really shouldve kept them for longer but hey the customer liked them more than i did lol
