Love it, but do your MATH! RMS is the key!
Wow, I had to do some math to figure out all the RMS, % of power, wiring, fuses, battery. This was a research lesson for me. I install this on my Pontoon with a Sony MEX-M100 400W-receiver and AMS-602W 60W-speakers and Piyle PLMRW 8" 400 W sub speaker ( I build the closed in case out of 3/4" wood) I am handy, but not a stereo guy. This is my first install of a sub amp. I have a stereo guy in the family and he knows the Ohms etc so well it makes my head spin. The key I learned is keep it at at 5 Ohms and figure out the RMS of each component. I searched tech sheets on the Internet for the RMS of each device. I also fund during other research that there was a good ratio I needed for good clean sound. My receiver is about volume 32-35, my sub is low to 1/4 boost based on the song and my receiver EQ and boost settings. I am happy with the results I'll leave my diagram below. Diagram Note: I did not use the capacitor and I tied the remote on to a switch as we listen to the radio with the motor off a lot. Lesson Learned. My family tech was not recommending I use the remote knob for bass control and told me I did not need a sub woofer with this high power amp, just tie the back speakers together to run the sub. I am so glad I di did not listen. I added the amp and the remote bass knob. Each song is different and its so nice to be able to reach down and tweak the bass. Here is what I found for this Sub Amp...which I love! RMS @ 4Ohms ~118W tests (calculations are 281W @4 Ohms) This fit my high power receiver and sub speaker just about right for my 8" sub was RMS 200W So in short, due your math for RMS. I found the Sub speaker should be double the RMS of the Sub Amp. I am very happy with the value and price of this Amp and the clear sound I hear.

Glad I ordered
My amp came in just a few days of ordering!!! I was already all set up pretty much plug and play for me besides a few wires I had to shift around. I got 1-15” kicker sub hooked up to this amp and and my stuff is knocking!!! I’m a drive around and listen to music guy. DIY install.

BOSS Audio Systems R1100M-S - Si levanta el bajo
Lo conecte a un Jensen J12W 12 inch 1200 Watt Subwoofer 4-Ohm, lo levanta muy bien podria decir que de sobra, siento que aun que el crossover lo ponga en una frecuencia baja llega a meter algo de voz pero aun asi es muy buen amplificador ya tengo con el desde septiembre 2023 y se ve que durara mucho mas. compre la version gris se ve bien de noche con las letras rojas.

Cheap and not as powerful as advertised
Nothing about this product is made of quality. Everything down to the fuses is cheapest of cheap, so the sound is bad and very poor for amplifing subwoofers. Buy an actual class D amplifier from a reputable brand. Nothing but disappointment from BOSS, even their "elite" lineup
