Default SD 800.4SEVO install

I will be installing a SD 800.4S EVO amp bridged. I will only be bringing in 2 channels (R & L) and wanted to confirm where to bring them into. I assume I should bring them in on channel 1 & channel 4. The output would be 2 channels but bridged between channels 1&2 and channels 3&4. Is this correct?

First of all, what evo are you running? Evo d/ evo x 2 or 4 ohm? Second what does the rest of your setup consist of and what speakers are you going to bridge?

On the input side of the amp you will need to use BOTH channels 1&2 to bridge channels 1&2 and do the same for the other 2 channels.

If using RCA inputs you can use an RCA "Y" (1 female 2 male). If using the high level input connect channels 1&2 positive and the same with the negative together.

I have a 2018 Street Glide Special and will be replacing the upper fairing speakers with GZ yellow baskets. I will also be adding GZ yellow baskets to the lower fairing. The left and right sides will be on seperate channels but the upper fairing and lower fairing speakers will be in parallel. I will be coming from the factory HU with 2 channels (right & left upper fairing speaker harness) into a DSP then with 2 channels into the SD 800.4S EVO 2 ohm amp. I plan on coming out of the amp bridging channels 1 & 2 which would connect to the upper and lower right side GZ's wired in parallel and bridging channels 3 & 4 which would connect to the upper and lower left side GZ's wired in parallel. I have attached my sketch for additional information.

What I am trying to confirm is where to connect the 2 channels coming from the DSP into the amp. My sketch is based on an assumption.

Thanks in advance

You don't want to run the fairing and lowers in parallel. The space that each speaker is in is completely different and the tune for each location will be different as well.

As Baby boy stated, you will need a 2 rca y splitters to attach to the amp. Left out of the hu to channel 1/2 and right out of the hu to 3/4 using all rca inputs.

Not out of the HU. Out of the DSP. In other words you need all 4 inputs on the amp covered.

Sounds great - that's what I was trying to figure out. --THANKS !!!

Also, would you suggest right and left in parallel vs. upper and lower. The speakers would be in sim places. Now that I think about it I might actually want the ability to adjust between the lowers and uppers.
