PLEASE do not get sony subwoofers. It would sadden me for u to have to go through the embarassment of having some of the worst subs ever made. I have had powerbass subs, bottom-of-the-line pioneer subs, and even DUAL subs that sounded better. And for way less $$ im willing to bet. The sony subs sound......terrible. like they have larengitis or cheapshittitis or sumthin. Please I beg of thee Don't get fooled by massive big-money marketing gurus who shove shiny red toys in ur face that have "1200 WATTS" written on them (LOL). And a hexagon(lols) Just ask and we will guide you, young one.
Type Es are OK, they just handle little power and need above average enclosure size.
Subs can last years in a properly designed system and seconds if mishandled.
The better way to suggest is by knowing the following: 1) what would be you max budget for speakers. 2) what would be you max budget for an amp. 3) a sub enclosure will be needed, how much space you have or willing to give up to place it. 4) what car are you installing this on.
Are u planning on putting the new subs in the boxes u alredy have? If so, what is volume of box? Ported? If so do u know the tune? ......Or arre u gonna put the new subs in new boxes? If so, how much space r u willing to give up for the box? Are u gonna build it urself? Prefab? Custom shop? Also, how many subs do u want? And how many watts RMS power u shooting for?
I agree with Joe. I had an x-plode myself. They seem to move air without producing sound. I gave that sub away. I temporarily borrowed a ten inch q-power sub from my brother in law, and it sounds a whole lot better. You can try out the x-plodes at Wal-Mart. They have the pioneers and the x-plodes. I would not use them even if I got them for free.
