How can I connect Bose acoustimass 5 series iv with RCA ends to Denon AVR 3802amplifier?

The output voltage on the secondary appears to be tapped at 22 and 16 VAC.

I know this is late but might help someone plus I had to repair the audio input cable going from my acoustimass 25 series II to the Lifestyle 5 receiver. The 13 pin connecter cable terminates to 2 RCA jacks (red/white) one 3.5 mm jack and a female RCA which is the digital sound source. looking at the connector with the 13th pin on the bottom, I reference the pins from 1-13 starting at the top left:

PIN 1 RCA (RED) center conductor
PIN 2 RCA (RED) sleeve
PIN 3 RCA (digital) sleeve
PIN 4 RCA (digital) center conductor
PIN 5 RCA (WHITE) sleeve
PIN 6 not used
*PIN 7 3.5mm RING (?????)
PIN 8 3.5mm SLEEVE
PIN 9 RCA (WHITE) center conducto
PIN 10 not used
PIN 11 not used
PIN 12 3.5mm TIP
PIN 13 not used

* the 3.5 mm stereo jack is used for system control on the back of the lifestyle 5 receiver, the cable that terminates to the 3.5mm is a 3 conductor cable that terminates to PIN 8 & PIN 12 but PIN 7 only has continuity from the pin itself to the white cable (within the 3.5mm cable) but not all the way through to the 3.5mm ring (where i would assume it to terminate). Maybe this is where my problem is, I don't know but I spliced the cable right before the 3.5mm jack and there was continuity between PIN7 and the white cable that corresponds to the 3.5mm jack I just dont know where its terminating too. If anyone can confirm that it is supposed to terminate to the ring of the 3.5mm connector I would appreciate it.

Plug the speaker wire from the speakers themselves directy to the receiver or you can plug them into the acoutimass module and the module into the receiver using speaker wire.

series ii ~$50 / pair

You don't say how "TV audio" is entering the system.

My guess is you're using analog audio Out from the TV into an analog input on the Denon. One channel failing would probably be the Left Channel cable failing or not seated.

I always recommend bypassing the TV audio entirely if the programming comes from somewhere other than its own antenna, as TV audio electronics add nothing good to the process.

If you're using cable box, sat box, game, whatever, ITS audio is best sent directly to your Denon's specialized audio hardware - digitally, if possible, to preserve multichannel possibilities.

You could also run standard analog audio from the cable box to the TV analog Audio IN if you just want to watch news and weather on TV speakers without the Denon involved.

The entire speaker system is passive. That is, it requires amplification for each channel.

From the manual: "Compatible with A/V receivers rated from 10 to 200 watts per front channel and 10 to 100 watts per rear channel; rated from 4 to 8 ohms".

How to connect Bose Acoustimass 25 series II subwoofer to Denon Receiver using factory provided 13pin cable

see the user manual and set the speakers at proper spacing and direction

Well,i can tell you are not very focus,cause you posted Denon AVR-2807 with Bose AC 15 problem,but under your details,you put down AVR-5807!
First of all,it is so unfortunate that you are NOT able to gain and experience to true ability in sound for this wonderful receiver when you are using a dual tweeters speakers and expect to have good sound separation as a TWO WAY speakers(a tweeter and a midrange-for true high frequency and mid frequency sound separation.)
Secondly,you have defeated the audio configuration of the Denon AVR-2807,since all your speakers are control BY the Bose subwoofer.
Now,i could show you a way to hook this up,and it doesn't matter how you connect them, they are the "bicycle tires" installed with a "Porche"engine if you know what i mean.
If you want a good recommendation for your "beast",i will more than happy to show you the way!
