Elite, do not listhen to Jonsey unless you want a shitty system.

.
I am competing in SQ this season, and hoping to take home some awards. (SQ is sound qaulity). Your best bet is to save up and go for the CDA 9847, and possibly the 9851 or 3. Why ? to simply put it any Alpine Deck below the 9847 will perform pretty much identical to other name brands such as Pioneer Premier, or JVC Arsenal stuff. AS for the type E woofer, If sounds extremely good. Sealed, or in a decent 6th order bandpass and you are looking @ some great sound. NOT some mind blowing SPL, but a very good expeirence. I will grab pics of my system in a bit and show you.
MY recommendations ?
CDA 9847
Alpine SWS-1242D (type S)
and
Sealed enclosure while feading that sub 200RMS @4ohms to 400RMS @ 4 ohms
The type E will do it, but you will be wanting more in the future. AVOID infinity products, in the last 2 years they have taken a dive. The days of Kappa are over for them. They are just naother Cookie Cutter box store band now. (Still decent, but not competitive).
