These speakers perform really well considering their price plus they fit in the doors of my cavalier perfectly with the plastic baffles provided. They rattle my doors with only my deck for power. First time I bought Alpine and I must say that I am impressed. You can't go wrong with these.

Received the speakers quickly and installed them in a classic Ford Mach 1. Speakers sound pretty good, could use more base but I think that is because they're only being powered off a sony deck. Overall, very happy with my purchase.

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.

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.
