Bridged 4 channel amp ..
Great stuff!!
Damn right. Good tech discussion keeps the forum alive. Most wont understand but for some of us it keeps the blood flowing upstairs.
Thank you Tesnevo and Slye.
Didn't mean to imply that this was the correct procedure/wiring for all bridging applications.
This is a damn good conversation Brotha as JL is s great example because they clearly define how to obtain bridged stereo and bridged mono. Some of the other companies were a bit vague about the stereo/mono and 2/4 channel stuff thus Flying Broke has been calling around the amp manufacturers digging in a bit deeper.
Like u said, it's technically a sin to play Zeppelin in mono so we have to get this shix right!!!!
Great stuff and good options, other than 200' of RCAs in the fairing, will surface as a result!!

I have a Soundstream PN4.540D that I was planning to "bridge" to run a pair of component speakers in the fairing. Other than the wiring diagram in the manual showing which speaker wire to hook up to which amp output, there isn't any other information.
I've emailed both Soundstream & Sonix Electronics asking the following questions.
...Are "Y" adapters required between the head unit & amp to run in bridged mode?
...Will the amp be bridged to stereo or mono?
...How should the "Y" adapters be connected to result in bridged 2 channel stereo?
...Since there isn't a channel switch on the amp, does it select the correct number of channels based on the way the inputs are connected?
So far, neither company has replied with answers to these questions.

The below scenarios relate to high end audio but will give you a better/broader understanding.
We use the rca distribution blocks, similiar to this one, on many theatre and stadium builds except they will have anywhere from 15 outputs per channel to possibly 40. Each and everyone of these we use has a conditioned line driver BEFORE the splitter that allows voltage isolation pre/per output. Meaning we can set each rca output at whatever voltage we need to get the signal w/o loss to wherever we need it to go. Some runs can be as long as several hundred feet to many yards.
The biggest problem with using these distribution blocks is they are not independently line driven. Every time you split a signal, we will use the pic you showed as example with 2 inputs and 5 out per channel, you will lose a small amount of voltage (mv) per split.
Typical , in this instance of a bike setup, factory head units rarely put out enough voltage to drive the distribution block at maximum efficiency.
Consider that anything with an actual output less than 2v output will need a line driver to "bump up" the voltage to the distribution block to minimize signal loss. Then you will have to factor in how many splits, how long each split run is and the requirements of the equipment (amp) each signal input is run to in order to match a line drivers output.
The better the sources output voltage/signal the cleaner/more efficient the amp/system will be IF and only IF it's matched to what the amp specs are. You ALWAYS want to match your equipment outputs/inputs or have an adjustable source to compensate for mismatched equipment. More voltage out is not always better as it's possible to overdrive an amps rated input.
Will it matter on a motorcycle, Good God NO!! Something on a smaller scale would work if you can mount it somewhere and get the cables run. You wouldn't notice any sound degradation unless your running a high end competition spl setup. If that was the case then you would go the route of a line driver/splitter, from the source, to your equipment to get/keep the output voltage up.
OR the easier way is to just have a custom made rca y adapter made for whatever application you need. Thats a hell of a lot easier. 1 input to 4-6-8 output will do the trick and a lot easier than trying to fit a brick in the fairing.
There are many online companies that will do these inexpensivly. Hence the reason we make our own.
Yes Tailwind, more rca cables......
