JUNK - Defective upon arrival
JUNK - one channel is distorted and very low volume. Both channels work fine with control turned all the way up. As soon as you step it down, it cuts out. Defective from the start.Also, Product description states "DESIGN: The speaker wire inserts use lock slips and are detachable allowing you to connect with ease to your speakers. It includes a metal mounting plate to place on a wall with matching plastic." Neither statement is true, wire pigtail connections and no metal plate.

Good product (when it wotks)
Ordered 2 of these for 2 zones in the backyard patio. One works flawlessly but the other one almost screwed up the speakers. Wanted to order another one but out of stock. After a long dsy of installation, kind if disappointing.
