Easiest way to verify mono or not is see if you have left and right balance. If you fade left and lose the right. You jave stereo. Typically if you select 2 channel and bridge you have balance. The Arc 600 is a prime example. Run y splitters and select 4 channel you will NOT have balance in bridge mode. Each manufacturer is different. I would try 2 channel first. Then y split if that doesn't work.

There are two ways to bridge this amp for two speaker operation.
One is for stereo (for our motorcycle applications) and one is for mono (when running 2 sub woofers for example).
The attached detail from the JL owners manual show you how to wire it both ways. Please note that the Channel Selector Switch is a different position in each application.
Using the the lower wiring diagram:
...Set the Channel Selector to "4"
...Install RCA "Y" adapters as shown to connect from your radio (or Line Leveler) to the amp
...Wire the speakers as shown.
Voila! You now have front speakers running from a bridged amp in STEREO.
By the way: Led Zepplin's "Whole Lotta Love" would suck in Mono!

Another one to test for good stereo separation is Bohemian Rhapsody by Queen....But I'm sure you already knew that.

Ok, here is a scenario question.
Since guys are starting to run more components in the fairing and needing/wanting more power for those and say either 6x9, M770s, M880s, or 8s in lids:
How would you run the RCAs off of one LL to two bridged 4ch channel amps?
Easy answer is run a second LL, but if fade isn't needed how would you run off of one LL?

So for u guys that tape the RCAs a certain color as u are splitting to keep from getting confused, in that case u will have 2 reds on the right of amp and 2 whites on the left. In an a nutshell it's about the right LL RCA tracking all the way to the right side of the amp and the left LL RCA tracking to the left side of the amp.
Clear as mud right?

In the case of bridging, color code the right side and track it to the right side of the amp. Repeat for the left.

Starting at the LL, just keep splitting till u have 8 males that will plug into the amps. Memphis Audio makes some inexpensive but mainly short Ys that will get u their. 1 male to 2 female at 18" each.

There is a potential. Noise bigger concern. Splitting typically drops voltage by only a tenth or two. Really if one was to do it properly you would use a line driver and be done. Wait for the area 51 to be released or go with the JL fix or similar. You would still split once, but really unless you just select 2 channel input. It just works. The splitting is done internally in the amp.

Ditch the LL and go DSP or a multi channel line converter You don't want to multi split the rca.
Lol, do what Slyedog said 4 minutes before my reply.
