Conclusion: Bought the alpine sps-406 from Sonic. Shipping was very fast. I installed them the very next day. The speakers sounded okay but after 10 hrs of playing trying to break them in, i raised up the volume and they sounded horrible. My stock speakers sounded way better than these alpines. I don't understand the big hype on these speakers. I don't get why so many good reviews. I should have saved my money. Good thing i didn't buy them for 69.99 or i would have been mad.
Conclusion: I installed these in the dash of my 02 blazer and even with 2 JLw6 12s in the back I can still hear my music with great clarity and they aren't even amplified. I would definitely suggest them to a friend!
Conclusion: Have owned these speakers for about 3 months now, and they are superb. Im glad I went with these. The clarity is unreal, and I only have them off of deck power. Cant wait to amp them up. They fit perfect in my 2003 Cavalier. Now I can listen to every kind of music and it sounds amazing. Sonic Electronix is the best too. Defiantly am and always will be a returning costumer.

Conclusion: The speakers themselves have a good sound quality, but they cant produce any bass whatsoever in my cavalier and aren't good with high volume. My 4x 10" Alpine Type-S in my trunk more than make up for it though. I should've gotten the Type-R's instead.
