You can definetly do better for the cash
Look here:
www.stryke.com Look at the PB series subwoofer
There are a few people on here now with these subs and everyone of them will tell you they are great. I own the biggest model, the PB15, the others wussed out and got smaller models that left them a trunk... wussies! :p
Mind you... this is what my trunk now looks like (notice my horrible temporary wiring job

)
