Hooking up 4 SRX-818 & 4 SRX-815?
 
How would you guys go about hooking up 4 JBL SRX818SP subs and 4 JBL SRX815 tops?

I have only 2 L & R xlr outputs from my mixer.

Should I hook up a Y splitter on both sides so now I have 4 XLR cables running to the 4 subs and from the 4 subs hook up the tops?

How would you guys do it?

Thanks

Yes..would give you the most placement options

What Mike said...but do you intend to array (place next to each other) loudspeakers that have 90° Horizontal dispersion?

I was thinking placing f them 12 feet apart from each other

each top will be on the pole that is threaded into the sub

I noticed the top has a mix out xlr output. I can also daisy chain it that way

Each sub has two channel inputs and outputs.
Lets take the left channel out of your mix as an example.
Run a line out of your left channel of your mix into channel 1 input on the first left sub. Take the channel 1 output of the first left sub and plug into channel 1 input on
the second left subwoofer. Now take the channel 1 output of the second left channel subwoofer and plug that up into the input of one of your tops. Now take the output of that left top and plug into the input of the second left top.
Should work.

Do the same as above with your right channel.

forget about the tops for a moment and think about placement of subs and what happens depending on their position (and alignment):

in order to sum, subs need to be positioned within a quarter of the distance of the wavelength of the highest frequency they are reproducing... - maybe you'll want some rear cancellation? or maximum spl? or the widest possible dispersion? all sub arrays need a specific approach/setup - and a speaker controller! get one and array subs properly/accordingly, do not use just a random spacing!
