Not sure if this is the right thread, and don’t bash me for these questions but I’m trying to learn. So everyone knows the stock audio sucks. I’ve got a 2020 streetglide and I believe I’m set on upgrading to a four speaker setup with fairing and lower upgrades running 4 Gzcf 6.5spl-neo and a Sound digital 1200.4-4. I’m wondering if this will be enough power to run them. I’m wondering if it will be ok to run channel to channel or if I should be running them “bridged.” If so how do I go about doing it? Since the speakers are 4 ohm wouldn’t that produce 2 ohm? Would the amp hold that? What size wire should I be running to the amp to support that power? Is 8 gauge enough? Is the stock wiring in the speaker pods good enough or should I put in better speaker wire? And finally what’s the equation and proper way to check wattage coming out of amp? I’ve got a volt meter but no specialty tools for this. Does anyone know a great amp mount for the 1200?

 

Did you buy the equipment already?
If you bridge the amp, you can only run 2 speakers. Running all 4 speakers on the 1200.4 (4Ohm) will give a good 200 watts to each speaker (when you set gains correctly).

 

The ONE thing I like about the Street Glides better than the Ultras is the air/oil cooling. I really miss being able to put some big fat meaty speakers in the lowers.

The bubblehead seems nicer when I'm sitting still in traffic but I believe I feel even more heat that I have to chase away with the wing vents than my old air cooled bike.

 

I have not, but I’m pretty dead set on running that setup. Heard quite a bit about it. I’m not 100% sure if I wanna add speakers to the bags later on, but for not I have lowers and fairing I already have setup for upgrades. I won’t bridge it if the amp has enough power, just heard a lot of guys doing so and wondering how with 4ohm speakers.

 

That amp should be enough for those speakers and run it 1 speaker per channel. (app. 200w per speaker) I would run 4 ga. wire to power the amp with a 60-amp fuse in line. I would set the HPF on the amp around 80-90 so not to distort the lows with that much power. Oxygen free wire for the power and speaker wire with a min of 18ga speaker wire. The 1200.4 should fit on the stock amp tray but you will need to get the HU flashed to either an 8/2 flash, rockford or soundz flash from a indy dealer as HD can't or won't do it. That setup should sound damn good when finished. If I may suggest, a mmats lsx 1400x4 is about the same price, much more reliable and in my opinion a better sounding amp with no annoying whine from a fan.

 

use the mmats lsx1400.4.

 

2nd that.

I had the 1200.4 - ran 8g OFC running 8 speakers...never had an issue.

Next time around, will definitely be buying the MMATTs over the Soundigital.

 

Don’t forget the Cicada FL1400.4. Power and clean and reliable and small footprint

 

I was eyeballing that one as well...and their new 700 mini.

The mmats is $600 & the Ciciada is $750. Curious if that extra $150 is made up in quality or is it the "new hot name" in the motorcycle game being used to balloon pricing.

 

Call around for the flx1400...6-650
