cheap amp to up speaker volume?

[Mkoll]

Ending up going with this Taotronics 20W bluetooth speaker: https://smile.amazon.com/gp/product/B013WPIGUA (was $40 when I ordered)

Stuck it to the top of my steering column cover. Works great and gets loud enough. Exactly what I needed. Thanks for the help everyone.

JBL has plenty of Bluetooth speakers that will get plenty loud enough for any car interior
