yes there is a 4 ohm and 8 ohm version
there is a whole dedicated victory audio forum on facebook
Maxx .... I will check it out. There is nothing Victory about my stereo system any longer.
All I can do is keep improving and that cost $$$. I'm actually working on sealing my bags better. Going to add the WD carpet kit and use either a better seal around the lid or get new latches. Mine seem sloppy.
The fairing has the VT Audio enclosures. Not sure they made much difference.
The Hertz Mille MPX 6.5 seem to do the best in the fairing. Very loud and clear.
I'm also interested in possibly another set of speakers in the lower portion of the fairing. What do you suggest here. Can I wire them to the Hertz in dash ? Not really wanting to add more amps at this time. The 600.3 has enough power and I won't give up bag space.
slik vic get over to the facebook forum there are at least 4 lowers some 8 inch lowers etc
your hertz are pretty good and would be a great example of what you would gain in the lid just add even more . i measured it today it's not even a inch difference of space in the bag .
i ran 106 sensitive 6.5 in fairing with hertz st 25 tweeters but swapped them out to a coax for simplicity and ohm rating to WDX6MOTO
coax 103db 4 ohm guys are running in the fairing and lowers and 2 ohm stereo or multi amps
you can run QPSM6V2 in pairs @4 ohm these are 106db each so all 4 would be 115 db with 1 watt of power lol but you would need tweeters that's why the WDX6MOTO is so popular you only give up 3 db and it comes with a tweeter .
your missing out they even have double din head units fitting in these bikes over there .
crutch field is a good source and yes if your under powered high sesativity speakers are a good choice they simply don't say how much better they are when you add power to them .
audio gets complicated pretty quick that is for beginners helping them to understand they simply are stating chapter 1 info . get over to the forum much to learn and a lot of it has been done for you . just remember it's all math and Physics you can't change it it's a give and take there is no perfect choice the numbers i gave you are fact you will get some audio guys who have not made the change to pro audio and they simply are not in the know . but most shops are getting there and so are the manufacturers don't let known or name brands or price sway you . yes a 50.00 speaker can destroy a 500.00 hertz speaker i'm not putting down name brand products they make solid products just don't believe the hype .
