LGSONE

Just finished this install, I bought the knob, put all the dip switches up except 6 and it sounds awesome for the money and use case. It is no dual 12's but those days are gone for this 50+ guy. Sounds great with some old school Metallica. Yellow and yellow black were in the harness so no guessing and for a 2020 Denali 2500HD I am happy with the result. Thanks to all for the pointers, made the install easy. 2.5 hours with a rain delay.
