Per my post above, bridging is possible but not very beneficial. They're better off using a higher powered module like two UCD400's or one UCD700 on a 4180 PSU:How, exactly, will you use the 4180 or 2180 to power the SI BM? Since these don't bridge, and even if power doubles at 2-ohm, it's still 360w, which, despite what Nick says, I think is a little underpowered.
I have a BM MKIV, and would love to use these amps. I saw BT a while ago, but always wondered how they sounded for SQ. IME, bikes generally want things LOUD, but not necessarily detailed or nuanced, since you can't hear nuances anyway.
Also, do you know if the 4180 could bridge two channels internally for 3-way operation? (the dream)
Then there's the whole too good to be true thing...
Yes, bridging must be done internally but easy to do. Though I am not sure there is much benefit, sounds like they are amperage limited and operating a single unit at 2ohm would yield better results than bridging two units at 2ohms (or even bridged at 4ohms):

For more power, a user would be better off swapping to UcD400OEM or UcD700OEM modules. This would require a custom Frankenstein amp and the current power supplies have not been tested to support this but in theory a BT4180 PSU would support a pair of UcD400OEM modules or a single UcD700OEM module.
The lack of gains hasn't been an issue for anyone I know who has used them, I think it is definitely worth trying. Hopefully we'll see larger module versions this year for people who need more power, especially for big midbass drivers and subs.No gain controls and no bridging are strikes against them for me.
Almost all big Harleys come with a full stereo from the factory. I had no idea either until just a few years ago.Not to mention all the road noise...the road noise on motorcycles must be like 10x higher than in most vehicles
I thought they made headphones for motorcyclists...
You mean you couldn't hear all the best subtle nuances on a bike like this going down the road with wind whipping at 80mph? LOL!!!The only thing I can say is how the hell are you suppose to hear the SQ of these amps over a LOUD ASS HARLEY!!???
So will you wire you SI BMMKIV one each channel with a 2180? And would this equate to 360w to the sub, since it's a DVC?The lack of gains hasn't been an issue for anyone I know who has used them, I think it is definitely worth trying. Hopefully we'll see larger module versions this year for people who need more power, especially for big midbass drivers and subs.
But yeah, I am definitely baffled by the Harley crowd

Is that Helen GA? If so, I live 45 minutes away and go up there with my family to relax at least 6X/year.
