Well I will 100% echo what Bruce already stated, This Amp Kicks Ass, and the HT speakers really come alive, although I do wish they had more Bass.
I followed the instructions on the Gain Adjust and think I have it pretty close but I am by no means an audio expert.
So the instructions said to turn the Gain all the way down and turn up the volume on the head unit until the speakers distort then back off the volume, then adjust the Gain for good volume, that's when the Amp really kicks in. At 19 the speakers are really pounding and my wife came out into the garage and asked if I could hear it yet
I used the same test song as J&M Audio uses on their instruction video, good bass, good highs and rocks........AC/DC - You Shook Me All Night Long
Per their info, you turn it up to max volume until the bass in the beginning riff distorts and then back it off, start the song again and adjust the gain the same way, and this song rocks. Keep doing this until your satisfied. I think my gain may be a little too high because the amp goes into a distortion fit for a couple seconds if I'm really cranking on the volume, so tomorrow I'll readjust before I put it all back together.
Bottom line I am a very happy camper so far
The pictures are the completed install with everything tucked away and wrapped up.
