Wiring tweeters
Discussion
Ok.
No not yet as it involves a bit of dash trim and door panel removal.
Probably easier with the tweeters which I might do in one go first and then get to the doors soon after.
Hopefully I’ll get to it over the next day or so!
Do you have any recommendations on where to start with the settings?

Mids LPF = 2Khz
Mids HPF = You can go as low as you like as you have no sub although the speakers only play down to 50hz. If you feel that they have too much bass and the doors are rattling, raise the Hz number. I had my 6.5" Audison mids @ 125hz, but I was running a sub also.
Highs HPF = 3.15Khz
6db cut-off for all
I noticed that the supplied cut-off for both crossovers was 4Khz. Which would mean that you would get a spike in volume at that frequency, which would explain why the tweeters sounded overly loud/bright.
I couldn't see anything in the documentation as to what frequencies you can crossover, so you may not have 2Khz and 3.15Khz. Look for frequencies close to those and try to leave ~ 1Khz gap.

Thanks for that.Mids HPF = You can go as low as you like as you have no sub although the speakers only play down to 50hz. If you feel that they have too much bass and the doors are rattling, raise the Hz number. I had my 6.5" Audison mids @ 125hz, but I was running a sub also.

But from what I can see I don’t have any settings to enable 3 way active on the head unit to enable the high and low pf on the mids to be adjusted. I have just one setting for that which is HPF on with adjustments or off.
Also, I see no way of setting the tweeters that high. The head unit only goes as high as 250hz.
I have also turned the gain up a tad on the amp for the mids and it seems to have lost some of its grainy sound so wondering if the speakers were under powered.
What I have discovered recently after watching a few videos is that adjusting one frequency can have quite an impact on neighbouring ones.
So, with the above in mind and the lack of adjustment for the tweeters I’m a bit concerned about removing the crossover that is at 4khz as I just can’t get anywhere near that and I am bit concerned about damaging them!
Leave the tweeters disconnected until you are confident that you have the settings right.
To help, download a 1Khz sample tone and maybe a 6Khz one, onto a USB.
Play the 1Khz one on loop with the Mid gain down. Turn the HU volume up until it starts clipping and then back it off a couple.
That's your HU max volume reference.
Then with the HU at reference volume, start increase the mid gain on the amp until it starts clipping. Then back it off a touch. That's the mid gain set.
Do the same for the tweeters with the high Khz sample tone. If the HU clips earlier than with the mids, treat that as the new reference volume. You can then go back and tweak the mid gain.
Alternatively play a selection of tunes you are familiar with that have a wide frequency band. Turn off or disconnect the channels/speakers as appropriate.
Then you can play about with the EQ if any frequencies are too loud/quiet.
The set up the Time Alignment. You may have to revisit the settings a few times when you make changes to other.
Try and also only play high quality recordings/formats. Otherwise you'll have everything set up and then play some low bitrate rubbish and be forever chasing your tail trying to get it to sound as good as previous music.

Fantastic thanks.
I think I’m going to set some time to do it all in one hit I think.
Also, I think some of the problem is I do listen to the radio quite a bit as well so I guess a good system is going to make a poor source sound even worse, especially when I am used to reasonably good factory fit systems in the past.

Ok slight update,
I haven't managed to get chance to do the crossovers on the mids but i had a spare half and hour and removed them from the tweeters and i amazed at the difference even just doing those makes.
Much clearer and certainly a lot less harsh, even without setting them up properly.
I am determined to get the doors done by/on this weekend as the weather is looking better so looking forward to seeing what difference that makes overall.
I spoke to another guy and he also suggested an Audison Bit10 DSP but i am really trying not to spend too much more!

Yes, i forgot to mention that i had set it up in network mode first, turned the highs right down on the amp, powered up and set the crossovers as per your suggestions.
And i am indeed doing it all arse about face, mainly due to time etc!
Is it normal for the high gain to be at about a quarter?
I appreciate that i still need to set it up properly once the other crossovers have been removed, but for now even at this setting they do seem to over power everything else a bit.

Gain is totally dependent upon the combination of hu, amp and speaker. Tweeters need little power to drive them, so maybe back the gain off for now and adjust if needed once you have the mids sorted?
Or just lower all the frequencies above 3.15k or whatever you have the HPF set via the EQ on the HU.
