I have these GZ coaxials in my fairing, bridged to my SD800.4 (old model), gain is all the way at the minimum and I still feel they are getting a lot, I am using a DSR1 and they are crossed at 75.
I am thinking of running them to Ch1 and Ch2 and re-adjust the gain but not sure if they will perform good this way, looking to run an extra pair of Mmats 8s coaxials inside my bags on ch3 and ch4 for some extra midbass as they don't need much power to perform. What do you guys think?

Thought of it but decided to keep it for now, just wondering how the mmats 8s will perform inside the bags, never heard someone did the same.

I dont know about the mmats 8". There was someone that ran the 10" in their bags and they didnt last long. May have been over powered. I do know that GZ yellow basket 8's sound good but will need more power.

Will try it for now without the 8s and see how the GZ coaxials perform this way in the fairing and up date the thread.

Within this thread there have been comments about where to set the crossover fq. I thought I read somewhere that setting your crossover freq. to either to 10 Hz above (high pass) or 10 Hz below (low pass) was a good place to start. The GZCF 6.5 SPL has a listed freq response of 50-20kHz so I was planning on setting the crossover fq. (high pass) at 60 Hz. Is this to low? Based on comments it sounds like somewhere around 80 Hz is typical.
P.S. I will be running an SD 800.4S 2 ohm amp bridged providing 400W to 2 GZ's wired in parallel (200W/speaker).

One thing to consider is how do you want these speakers to sound? If you want as much volume as possible then feed it watts. If you find that you want some more low end lower the wattage going to them so you can lower the crossover point. Crossovers in the 80s probably sound fine but I left mine set at 50 with 150 watts going to them and really like lows these things produce. I can still crank them plenty loud and can hear the bass guitars as well as the kick drum while out on the highway. The other six speakers I have in play have higher crossovers since they have to overcome more distance and wind noise than the fairing speakers do.
As always ymmv.

correct me if I'm wrong but the only way those speakers would see 400 watts is if the gain is up and your at max volume. I also doubt that amp is gonna produce a true 400 watts per channel
I'm not here to argue as truth be told I dont know much about audio. I do know numerous shops and guys that have competition bikes have said to run that amp bridged. Yes a few said keep gain a minimum and watch the volume. Some also said a dsp would be greatly advised but not neccessary
150 watts at full volume is gonna be less loud than 325-380 watts at 1/2 3/4. I understand where some guys say it's too much. If it is then it's my fault and I was warned. No biggie
I will more than likely this spring take it to 77 customs or jefe rings to get properly dialed in. Until I will play around with it. I do know almost all said the perfect amount is about 300 325 watts

I ran mmats 690cx 6x9's in my lids for almost 2 years in my previous bile...probably no more that 100 to 125 watts....guessing....and could hear them fine. More watts isnt always whats needed to hear your audio.
Guys here have given you THE best advice, which as mentioned is unsolicited. Some of the guys here live and breath audio even as a hobby, and have more knowledge than many of the "audio shops" around doing this professionally. They have nothing to gain from not being truthful. Do what you want, you really are "that dude" lol........
