what are some good 10 subs?

i just did a install in my buddies sierra.. doors were replaced with polk components and had dual 10 kicker cvrs. dont get me wrong ive never really heard eclipses hit but i have to 12 inch kicker cvrs and havent found a speaker i like more... just putting in my imput

A set of MB Quart 4" reference components up front, 4" reference coaxs in back, and 2 10" eclipse aluminums would be sweet.

Just to clarify, they didn't break due to "underpower."  They broke because of amplifier clipping or from being in the wrong enclosure.  "Underpower" does not break subs, improper system setup breaks subs.

i got a pair of kicker compVR 10's each one with just .96ft3 sealed.  the absolutely are some of the best sounding and hardest hitting subs i have ever owned.  i also have a pair of comp 12's, the 10's blow them away.  i had them on the same amp in boxes built to optimum air space and although the 12's sounded good, the 10's are phenominal, plus the fact that they don't take up hardly any room in my trunk, most people think i have a pair of 15's.  although i am pushing about 500 watts per sub,

eclipse is a very good brand, i used to sell them, but they are a bit pricey.  don't even think about a titanium under the seat in your truck. you have no where near enough room, the are a very deep sub, the mounting depth is almost 9".  you only have around 9" total under the seat, then you have to subtract wood thickness and ground clearance.  the comp vr10 has a mounting depth of about 5 1/2". trust me go with kicker
