Amped Up Hemi

I recently upgraded my salad bowl hemispherical speaker with a new amp board, and I’m loving the sound. I get more volume with less distortion.

This 6-channel board (Sure Electronics TDA7498) is significantly more powerful and easier to install than my previous configuration of 3 stereo amps. I had to use a router to make room for the cooling fan, but otherwise the installation was straightforward.
