I have a compnent system in my doors. I had best buy install it because I really didnt feel like it. New GF at the time.. Anyways, I think they were either pioneer or alpine, I cant remember now do I really care. I Asked the guy at the store and he said they were the best for the money. They are pretty sweet. I have a peripheral so I can hook up my iPod to the factory stereoand it sounds great. I did dynamat the doors and used speaker kits so nothing rattles.. It sounds great, but could still use some more bass if you really want it to rumble. Definatly loud enough for me and my friends with the windows up or down. make sure you secure the control boxes ver well. I had one fall off while I was out in the desert. 1 zip tie later and it was all good.
