Optimize my sound system
Keep diamond amp use it for the mpk's and st25 horns. Get a soundigital 800.4 4ohm or similar spec amplifier and either Beyma 6p200nd or faital rs140 6.5s to replace you're 6x9s and make a adapter plate for them and horns for your lids. Use the sd800.4 to power new 6.5s and sv165 each pair in parallel. You will need to do some adjustments in your dsp but unfortunately I am not well versed with the dsr1. Here's a n example of how it would work... I know it's not pretty
I think the biggest reason you havent gotten a lot of advice is because not many people here have experience with those components in your system so its hard to give accurate advice.
I did some testing tonight after I got back from working on painting the bike and @InthewindMN you are 100% right, separating everything to individual channels definitely cleaned things up and seemed louder.
I disconnected everything, pulled the MPK junk tweeters and crossover out entirely then ran just the MPKs off channels 1 & 2 of the Micro84u and adjusted the tune on the DSR1. I was able to turn the amp all the way up and it never distorted (unlike before) which makes sense because the speakers can handle 110 watts and the amp is only pushing 90 watts per channel.
Then I put the SV 165s on channels 3 & 4, unplugged the MPKs and did the same thing. Again amp all the way up and the speakers never distorted, which again makes sense because they can handle 200 watts as @c_mancuyas8 graciously illustrated.
Just for the sake of trying, I then put the BT2250 on the Sub channels coming out of the DSR1. I left the ST25 horns in line since they have similar power specs (which is a disappointment as I was under the impression that the Hybrid Unity 6x9s wanted 150 watts), but that did NOT work. The BT2250 is presumably pushing way too much power and when I turned on the bike the 6x9s made a LOUD pop sound. So I disconnected the MPKs front channels 1 & 2 on the Micro84u and connected the 6x9s and ST25s in their place. I didnt put the amp all the way up, since the 6x9s are rated lower than the 90 watts it pushes, but both the 6x9s and ST25s sounded very clear and louder than they had been.
So, the answer to optimizing the speakers I have is definitely a second amp, and the SD800.4S c_mancuyas8 mentioned seems to be a solid fit pushing 110 per channel which matches the MPKs perfectly. Leaves a little on the table for the SVs, but would probably be the smartest and most economical move. The Diamond Audio HXM800.4D is $200 more and only pushes 10 more watts per channel.
@c_mancuyas8 Your idea of replacing the Unity 6x9s is very interesting, and both the Beyma and Faital 6.5s you listed are VERY compelling. It got me thinking that maybe I should pull the MPKs and put the Faitals in the upper fairing, but I dont know what amp could fit in the fairing and push the 200 watts they and the SVs could handle. Realizing that the Unity 6x9s are only 75 watt speakers (though they sounded pretty good) definitely got me thinking about alternatives. Since I already have the Micro84u and it is sized about right to power the Unity 6x9s on channels 1 & 2, and then the horns on channels 3 & 4 I may just keep it for now, but it got me thinking about maybe looking for a 5 channel amp for the saddllebags to run better 6x9s (or somehow convert to 6.5s like you suggested) on channels 1 & 2; the horns on channels 3 & 4; then perhaps an 8 or 10 in the saddlebag too. Is that the way to go, or should I get a third amp if I put in an 8 or 10 sub? In either case, if I add a sub, I assume Id need another DSR1 because it only has capacity for 8 channels. Is that how folks with more than 8 channels do it.. multiple DSR1s, or is there another way to manage it? Since Im now knee deep in all of this, I would like to know what it would look like if I added a 10 sub to one of the bags. What sub and what amp should I use?
The options Im now considering are:
Option 1:
- Add an SD800.4S and use it to drive the two MPKs and two SVs
- Move the Micro84u to the saddlebag and use it to drive the Hybrid 6x9s and four horns
- Pull the MPSs and replace them with the Faital 6.5s
- Figure our what amp to use to drive two Faital 6.5s and two SVs
- Move the Micro84u to the saddlebag and use it to drive the Hybrid 6x9s and four horns
Option 3:
- Figure out what amp and sub to get to add to the saddlebag
- Depending on if the sub needs a dedicated amp figure out where to use the Micro84u and 2nd/3rd amps

I would definitely have to put two amps in the bags, somehow with the speaker pods vents and glove boxes that big shark nose doesnt have a ton of room in it.
I think Il start with the SD800.4 to drive the four fairing speakers and maybe a SD400 to drive the 6x9s and horns if I can fit that little guy under my stereo, if not maybe reuse the Micro84u if I have to put it in the bags. Probably as a next step, Ill swap the Hertz speakers for some more powerful ones. Then if Im willing to lose bag space and need some more bass Ill pull the 6x9s out and put one 8 in each bag with another amp, or leave the 6x9s and add the 8s but Id have to look at DSP options then because Ill have all 8 channels full.
Thank you SO MUCH for all your help!
Also need to plan ahead for the speakers you want to run and wiring strategy bc that amp is 2 or 4 ohm if you use the faitals in the future you'll want 4ohm because they're 8ohm speakers. If going with 4ohm speakers you'll want the 2ohm version

I believe it fits in the shark nose and has some decent specs wattage wise. Depending on speaker choice, it may need dialed back a little, or the other option would be to wait for the new SD amps coming out.
