Good sound quality for the money. I put this sub in my 99 Mercury Mountaineer in the stock sub box after the stock one blew. It was powered by the stock amp. Big improvement over stock sub.
This Kenwood KFC-XW800F "Is like that". I've never order a sub this small and wasn't expecting much w/the size I ordered. I was really surprised after installation. Gave me just enough bass where needed.
