With the 4ohm version, you have the ability to run 8 sets of 4ohm speakers, paralleled to 2ohm, and give every last one of them up to 335 watts if you needed to.

that's kind of what has had me on the fence.
The 4 ohm version definitely puts more power on the table to be used by my fairing and lowers.
The only reason I was considering the 2 ohm at all was the ability to bridge channel 3/4 to take advantage of the 1 x 1200 at 2 ohm to dedicate for lids or bag speakers. Figured that would give me more choices for running a pair of 4 ohm speakers I could use in the lids or bags if I upgrade latter.

If you go in the bags that gives you 600 watts per speaker which will be light on watts for a 10. 2 8's in each bag would get 300 watts each and still light on watts. A single 8 in each bag is purely a waste of time. And a 6x9 in the lid and an 8 in the bag would share the same tuning if you went 2ohm. Just food for thought.

Dang, I figured 600 watts each to 10's in the bags would be enough to get them rockin!
So that brings us back to the 4 ohm version probably being the better all around choice.
Are there any good 8" options for the lids that would work well off channel 3/4 off the 4 ohm version?

T, I'm running Four GZs total - Fairings and Lowers. GZs left upper and left lower parallel, then right upper and lower parallel. At 33v I should be right around 275w with a little headroom.

Had I gone with the 2400 I would have gone 4 ohm.

well I’m glad you are running them that way instead of fairing on one channel
and lowers on the other. I’m just still a fan of running stereo instead of mono. I know that I am leaving power on the table but stereo to me is better SQ than power any day of the week.

Good point, makes more sense left fairing/lowers off 1 channel, right fairing/lowers off right channel, especially if I'm running the same speaker in both locations. I definitely prefer the stereo sound vs mono. I've run stereo in all my bikes up until now.

That's actually debatable. I'm not running stereo on any part of my setup and I do not lack SQ. The issue you run into when paralleling left fairing and left lower is tuning. Although they're the same speakers, fairing and lowers require different tuning parameters.

You're using a dsp correct...the speakers will not be in mono. You can select L&R input in the setup of the dsp so the speakers actually get stereo sound, just not the stereo separation. Why folks are spending this kinda money for sled audio and still hung up on stereo separation in the wind at 70mph is mind boggling.

It is because I spent all this money on my audio IS the reason I want it in stereo. I can hear the separation from my setup at any speed even with these old ears aven from the compression drivers in the rear lids. That is why I got a dsi-3 so I could have all my speakers in stereo and on their own channel on a dsp. I know I am giving up wattage to the speakers but to me the SQ from stereo and the way music is intended to be heard by far exceeds running parallel and bridged. Before I got this dsi-3 I had my lids running off 1 channel of the dsp in mono and the bags running off 1 channel and was just missing that stereo separation and although it was loud, it didnt have the stereo from the rear at all. That was just unacceptable for me. If I couldnt hear the difference then I would be ok with it maybe but knowing how tunes should sound and not having that by not having stereo just lacks in SQ in my old opinion.
