It's not my thread to hijack.
These setting should be a good place to start. You can try adjusting the EQ Bands some to your liking and music type.
The setting below can also be adjusting some. I wouldn't go down on the front speaker FC thou.
The BT 6.5 speakers tend to be a bit bright you could try lowering the upper EQ bands 11 - 12 - 13.
When your done post a video if you can.

Way to take the bull by the horns Bert. Glad to see you figuring it out and sharing. I'll sit back and observe. LOL.

 

Couldn't have done it with you and MotoMike and probably some others.
As you already know the Kenwood 998x is an excellent HU. Not some much if you just take it out of the box, install it and ride off. Happy to share so others can enjoy it as much as I do.

 

Bertie - I am running BT2180 amp, Bt7.1's and of course the 998. Do you suggest any setting tweaks from your original recommendations?

 

Bertk not Bertie. Dang autocorrect. Sorry. LOL

 

You can do some fine tuning in the areas suggested to nemick in post #11. The only way to know is to listen to it. If you make a video and post the link here that may help us make suggestions.

 

Sounds like frinkin awesome.....Well done.

 

Thanks for the feedback. These setting should have taken some of the brightness out of the BT speakers.

 

Bert maybe Slye can comment.....you have bands 12 and 13 raised to 3, but then have the tweeter volume is -3. Since most HU don't have that tweeter option and honestly I'm not exactly sure how it works with the 998 and coaxial speakers?? I should read the manual . I could see how it's useful running an active set up...but why not just EQ the higher freqs to reduce any "brightness".

 

Very good question/comment Haze. I did some research and couldn't fine anything on Tweeter Volume. Just thinking out loud here and not trying to over think it. As far as I can tell the tweeter volume would reduce the volume of all the frequencies coming through the tweeter where as the EQ would reduce or increase the volume of specific ranges of frequencies. I am very interested on what others will have to say and how these setting apply to speakers with and without crossovers.
