Nice speakers for under 50 bucks!

I ordered these for my Tacoma front doors and they sound great. I'm going to order a second pair of these to replace the rear speakers now that I know how they sound. Excellent value!

Great for the price!

What can I say? The speakers in my rear doors were paper garbage, OEM from Mazda. These neither distort nor disappoint for such a low price point. These are real quality at a steal.
