Help please I'm new to this and I would like some feedback
Has anyone ever heard of acoustic amps and subs? I bought an amp and an 10" sub for 100$ I know it sounds to good to be true but m not sure Any help?

I remember that company from back in the mid 90's. They were ok amps back then... Summit Racing used to sell them. They weren't the cheapest, but they weren't super expensive either. Not sure about the newer stiff.

Thank you for the help!
when I install them I'll let you know how they sound
