Subwoofer durability? Options

[FreddyTheOthaMea...]

So I dont know if its just bad sales reps selling me whatever they want or whatever but it seems like i rip thru subwoofers really fast (either the VC blows or with my infinity subwoofers the wire that connects to the spider on the cone actually physically seperates) what would yall suggest for a 1000 watt (MAX) amp (kenwood excelon) ? I was rockin 2 12" eclipse titanium subs that just blew after about a year and a half of use/abuse which is the longest ive ever made any subs last. they would usually blow after a couple of weeks and then the sales rep would act like i went out of my way to destroy it when i would try to get it replaced.

see thats the thing, as far as the controls on the amp were concerned i left them turned all the way down (gain, input sensitivity) and only dinked around with the controls from the head unit, so lets say i have a bass control on the head unit that can increase bass i would usually put it at 9/15 and bring the actual volume of the system usually around 28/35 (or 32/35 when it comes to my mp3 player because it plays back more quiet than a cd) so i dunno if having the head units bass up to a 9 out of 15 would really qualify as "peaking out the amp" but any advice would be great since the local shops are apparent douches, again thanks to everyone for all the input
