I used this to start with when disassembling and reassembling a Polk soundbar as it would not turn on until unplugged and reconnected plugged in, a speaker case made and just velcro on the outside of the MDF case I used to have 7 speakers hooked up and didn't have a frequency splitter for treble, mid or bass, but hooked up all 3, a 2 channel connection is probably not recommended and aux to tv not the best best sound quality. But I use it every day and for the price I've brought my soundbar and subwoofer back to life. TV volume with remote control and/or via Bluetooth. I am very satisfied with this product. I've used it in many different projects including portable speakers and home theater. If I had to upgrade, I'd like to find one with a dedicated bass channel and an optical sound option for better sound quality. The rest are very satisfied.
