2020 JBL System Upgrade - Final Review

Finally got everything installed and tuned and wanted to comment on the final outcome.

Gear:
Head Unit - Stock JBL
Amp - Infinity Kappa 5-channel
DSP - Rockford Fosgate Maestro DSR-1
Front/Rear Doors - Hertz K170 with tweeters
Dash Rt/Lt - Kenwood Excelon KFC-X2C
Center Dash - 2X JL c1 tweeters
Sub - Tech12volt custom sub box wit 10" JBL sub
Sound Deadening - Noico 80mil on doors and rear wall.

The last part of this project was to replace the dash speakers tonight with the Kenwoods after finally getting the plug-in-play harnesses. Initially I was a little disappointed that I could hear the Lt/Rt dash speakers as being two separate speakers and the center channel was getting drowned out. I then used the Perfect Tune app to connect to the DSR-1 and I used a tape measure to input the distances from each speaker to my head to program delays and the result is a perfectly balanced sound stage which seems to have made the left/center/right speakers melt together. I'm now convinced the Rt/Lt dash speakers are hooked up to the door speakers (this was being discussed in another post) as this process with the DSP was only supposed to affect the door speakers but I hear a huge difference in the dash speakers as well. I'm very pleased! A shout out to James from Tech12Volt for his help - I had many questions and he was always willing to help and he was always a gentleman. I really enjoy the truck sooooo much more now! Volume is much louder as is the amount of sound being produced. The single 10" sub hits hard and I can't imagine the need for anything more. Sound is crystal clear all the way up to levels that are almost too loud to endure for long.

The best part is in an hour I can have the truck back to stock - everything is plug-in-play.

 

Do you have the same audio hiss attributed to Bluetooth in the post quoted in https://www.tundras.com/threads/help-with-keppa-5-amp-settings.63602/#post-1664614? I was leaning towards keeping the OEM HU but this audio noise issue has given me pause.

 

The hiss is only present when you try and turn up the gains on the amp. With the gains all the way down the system is still significantly louder and better sounding than stock. What I plan to do is to turn the truck on and turn the gains up as much as possible just to the point where I can hear the hiss and then back off a little. To be clear, I hear no hiss while music is playing even with the gains all the way up - it's only when no music is playing.
