I have bought two of these speakers for two of my cars. Both cars have 50 watts x 4 head units. This speaker is AWESOME!!! I love the sound. I would recommend putting bass blockers on it.
I bought this because I just got my back dash recovered and didn`t want to cut my new vinyl.I used to have 2 back dash speakers.Don`t waste your money.Get kick panel speakers or under the seat speakers.It sounds horrible.I realize the speaker is small,but I expected a better sound.I would have returned it if I hadn`t recycled the box.Ihave a63 falcon.Shipping was fast and efficient.
