Problem with master and slave sundown amps

[46panel 10+ year member]

I currently am running two sundown 1500's on two Fi BL's and have my rcas from the head unit going into one of the amps inputs then have another set of rca's coming from the output of the master amp into the input of the slave amp. I know the sundowns dont have a master and slave switch but heard they just do it internally. I set the amps the same just by looking (which I know isnt as accurate as using a meter) but it still shouldnt be this far off, because one sub moves so much more than the other. Currently will be adding the third sundown on the third BL but need to figure out why its like this with only two.

You have to do it differently. Download the manual from the web site

Did you look at the way that the subs are to be connected?

Dont you only have to connect the amps with a speaker wire if you are only running one sub with two amps?

As far as I know, you must use the master as the positive and the slave at the negative speaker lead. And the 8 wire must be put in between for the automatic switching to work right. The subs must be wired to a minimum of 2 ohms, according to specs, but you may be able to get away with 1 ohm.

Post a photo of your speaker wiring.

I didn't think my saz-1500d was .5 stable either

My wiring is a mess at the moment. I just received the amp and wanted to test to make sure its working. I have 6 bolts coming out of the box. 3 positives 3 negatives. Then just have it connected as 1 positive bolt to 1 postive on the amp 1 negative bolt to the negative on the amp same way one the second amp. Then a rca wire as pictured above.
