Needs a **crossover** and a dimmer
I can't believe the kit didn't include a crossover! If someone, like me, is piggybacking on the subwoofer out port, you get undesirable vibrations in your seating. I purchased a passive crossover for ~$15 from Amazon, and was able to eliminate the higher bass frequencies that were not supposed to be tactile. That suggests to me that the amp you sell was not purpose-built for this use. I am very disappointed that I had to troubleshoot and fix a problem that shouldn't have existed in the first place.
Also, you really need a dimmer on the amp! The LED display is way too bright! Who wants a bunch of Red, green, and I believe yellow lights glaring from a device in their nice, dark home theater room?
