Configuring the amp using 1 set of RCA cables

Yes, it is possible to add a Sumo amplifier to a Denon AVR (Audio/Video Receiver) system. The Denon AVR is designed to be the central hub for audio and video processing, providing amplification and routing signals to speakers and other audio devices.
To add a Sumo amplifier to your Denon AVR system, you can follow these general steps:
1. Determine the audio output options on your Denon AVR: Check if your Denon AVR has preamp outputs, which are typically labeled as "Pre Out" or "Main Out." These outputs are used to connect external amplifiers like the Sumo amp.
2. Identify the input options on the Sumo amplifier: Check the inputs available on the Sumo amplifier. It should have an input that matches the output from your Denon AVR. The most common connection is RCA, but there could be other options like XLR or optical.
3. Connect the Denon AVR to the Sumo amplifier: Use appropriate cables to connect the preamp outputs of your Denon AVR to the inputs of the Sumo amplifier. For RCA connections, you will need RCA cables with male connectors on both ends. Make sure to match the left and right channels correctly.
4. Configure the Denon AVR: Once the connections are made, you may need to configure the Denon AVR to use the external amplifier. Check your Denon AVR's manual or menu settings to disable the internal amplifier for the connected speakers. This will ensure that the AVR sends the audio signal to the Sumo amp instead.
5. Set up the Sumo amplifier: Follow the instructions provided with the Sumo amplifier to set it up correctly. This may involve adjusting gain levels, selecting input sources, and configuring any other settings specific to the Sumo amp.
6. Test and enjoy: Once everything is connected and configured, test the system by playing audio through your Denon AVR. The audio signal should be amplified by the Sumo amplifier and sent to your speakers, providing enhanced power and performance.
It's worth noting that the specific steps and options may vary depending on the models of your Denon AVR and Sumo amplifier. It's always recommended to consult the user manuals for both devices and, if needed, seek assistance from an audio professional or the manufacturers' support teams for detailed guidance tailored to your specific equipment.

This MIGHT help a little

The way the EQ is hooked up is correct.

You set the factory radio to a set level, then use the volume on the EQ for everyday adjustments.

I believe your problem lies in the amplification.
Your BOSE amplifier was made to run a 4 channel 8ohm stero load.
Low powered - high in sound quality.

You have swapped the factory 8 ohm speakers (15W) for 4 ohm power hungry ones.
Now the amplifier is working harder to produce the same output.

You would be best served eliminating the factory amplifier and getting 1 good 4 or 5 channel amp to power your speakers.

a 4 channel amplifier could be used stereo (left and right) on channels 1 and 2, (2ohm stereo load)
and bridge channels 3 and 4 for your subwoofer.

For a true surround sound - a 5 channel amplifier could run each speaker individually, and the 5th channel is reserved for the subwoofer.

a small dedicated 75wx4 channel amplifier with built in crossover, and level gain controls - would blow your socks off. It is 200x better than the factory 12Watt amplifier. Your ears will love you for it :D

Pretty Straight Forward get a 8 or 4 gauge amp wiring kit.

Run your hot wire to the +12V from the battery make sure to install the supplied inline fuse near the battery don't connect to the battery until installation is complete.

Run the REM to your stereo power ant. Wire. if available.

Run the GND to Metal Chassis Ground keep it as short as possible.

Run the RCA Cable from the back of the Stereo to the RCA Inputs or Low Level on the amp.

This amp is 2 Ohm Stereo Stable which means you can connect 2 (4 ohm) speakers in parallel to each channel or 1 (4 ohm) speaker on each channel or you can connect 1 (4 ohm) Speaker in bridged mode.

There are other speaker configurations you could use but you cannot drop the load below 2 Ohm in stereo mode and no lower than 4 ohm in bridged mode.

Hope this helps

Assuming you really want to have a working surround system you will need a separate stereo amplifier for the 901's to accomodate the need for the Active EQ. There is no way to separate your receiver's front L&R channel preamplifiers from their amplifiers.

I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver and the 901's amp channels. My receiver controls everything and just drives the Center and Surrounds. You would probably just get a nice 2-channel amplier for the 901's. However, the TX-SR606 doesn't provide power for a Subwoofer, should you decide to get one, so you would need another amplifier channel for that, too. Therefore, you might look around for a powerful 3- or 4-channel amplifier so you could drive the Sub, too.

Modest amps would work but at very loud volumes may go into clipping, which is bad for any speaker. I'm using only 100W for mine and it has plenty of steam for the 901's.

For connection I would run a pair of RCA cables from the Front L&R Audio Line OUT to the Active EQ's Line IN; then the EQ';s Line OUT to a separate amp's Line IN. Attach the 901's to the new amp, run through the receiver's setup procedures for volume, etc and you're done.

Not what you might want to hear but 901's have special requirements. I've had mine for 25 years and have no regrets.

A seperate subwoofer channel on the amp could be used. Just run a single RCA channel from Sub OUT to one available channel IN on the amp and attach the subwoofer to it. Two would work, also. That's what I do. You could use a 1-2 RCA splitter to feed two avaailable channels on a 4-channel amp. The iterations are many. Have fun.

You will get a Lot better Results with the 2 Amp. Setup. I have 3 in my 95" Silverado and Mounted them Under the Back Seat (Xcab) Works Great! Please Rate My Response! Thanks!

I have a VSX-36TX so this is how it's going to work...

You can plug into the left channel and it will feed both the left and right channels.

To confirm that it's feeding both channels, connect the speaker to one channel at a time. With signal fed into the left channel only, you should get sound when you connect the speaker to either channel.

You can do it either way it doesnt matter.

first thing 1000@4 means 250w per ch. which means150w usable power.the mode switch is only to reduce rca cables,use 2ch mode if only 1 pair rca available,60hz is a bit low for this amp,90 would work better.

Yep! It's called a Y-Splitter. They make different variations of them: http://www.computerplug.com/img/cables/CRCA-YFFF.jpg https://www.wiredco.com/catalog/images/PYTHONRCAY.jpg http://4netconnex.com/images/products/8-2521.jpg
