I use to have 2 jl 10w3v2 subs powered by a memphis st-1000d amp, there were in a sealed box under my rear seat. I blew those in about 2.5ish years. I decided with my next setup im gonna stay with my amp, however for my subs I wanted something other then jl. My beef with jl was that although they sounded very clear and precise, they just wernt loud enough for me. I was thinking 2 dd audio 1510 in a ported box, however I was told that my sq would be down quite a bit. They then recomended me 2 idq10 subs in a sealed box and said that would be plenty of output for me. Can anybody give any suggestions to this or possibly other subs with my desires?
fyi I am lifting the back seat 2 inches.

plain and simple, without a seat lift, you are not going to get a lot of output under the seat. You wont find much that will be louder then the W3s under the seat without the lift. You many want to look into doing the lift and doing 2 12s under the seat.
