Alpine type-e is the most reliable sub!!! Options

[Niskyspy]

Ok here is the deal. I have a 12" Alpine type-e in a sealed box and its RMS is 175watts. So every day for the last 3 month I was running it at 200-300rms watts for about 2.5 hours daily and 350-400rms watts for 10-20min every other day. And the thing still didn't blow on me. It does disturb when at around 350watts and starts loosing it but it works fine. I am trying to kill this thing as slow as I can cuz in march I am gonna be getting W6V2 with ported box which sould make a lot more base. I just ran an SPL on the type-e + Kenwood 500rms 4ohm stable and Panasnic deck with 5v pre-output today and it came out to 138db's which is pretty good for a system that costs around 500$ (well its 500$ for me cuz I bought all of my stuff exept my amp from my friend who gave me a lot of cheap deals).
