My opinion on kicker
I installed the Kicker system, with amp and subwoofer. The quality of sound was definitely improved, and sounded good.. BUT... it didn't blow me away.. And for this price it needed to blow me away to keep it.. Here is the original youtube video i made of the Kicker install. After 30 days I ended up returning to Crutchfield for a refund. I decided to put my time and effort in, and get an equal (or better) sound system on my own. I installed new door speakers, and a subwoofer with a custom fiberglass box to resemble the kicker box. I spent approximately 30-40 hours making the box.
Pros: The ease of install! Super easy - plug and play. I did it all in one night (under 4 hours). The system sounded good, but I thought i could make a system as equal for less money (just a lot more time!) Crutchfield was awesome for return policy. I had it for 30 days to test out, listen to different artists, and decided to return it.
Cons: The price!! Like I said, I was happy with it, and it sounded good, but for the price the system had to blow me away..
