I have a gaming chair that has 2 speakers in the headrest. It has a RCA Audio output jacks. I want to plug this into my Kenwood VR-605 receiver into the 'Surround Speaker' inputs.

The problem is that the receiver inputs will only take speaker wire.

Is it just as simple as cutting off the end of the RCA cable and splicing it down to the copper wire?

If so, should I expect the same results as if it were any speaker or is there potential loss of quality?

Also, my gaming chair has its own power and has a Volume knob, Bass knob, and Vibration knob. Suppose I am able to plug it into my VR-605, do you think these will work?

Will it mess it up if I have my receiver volume turned all the way up and then turn the volume knob up on my chair?

You seem to be a bit confused. RCA jacks are typically used for a line level signal. This would be in the general area of 1 volt.

Speakers outputs are for powering speakers and produce many volts. You do not want to hook up speaker outputs to RCA inputs.

How about pre outs? A record out likely won't work as they as restricted to analog.

What you can do, is find a speaker level to line level converter. Try partexpress.com

First, the chair/speakers have RCA inputs and the Kenwood has speaker outputs. Second, while one can just cut off the RCAs and connect the leads to the amp, there is no assurance that this will work and not damage the components.

So, what you really need is a speaker-to-line level adapter. You can Google it. They run from about $5 to $30 per pair.

Finally, you cannot turn the receiver volume all the way down and recover it in the chair electronics because there will be nothing to recover. You have to have some output level from the Kenwood.

The main problem isn't the connectors, it is that the receiver have speaker-level (high voltage, high power) outputs and you need a line-level (low voltage, low power) signal. The other thread already established that your receiver does not have pre-outs (line-level outputs for all channels). So you'll need a speaker-level to line-level adapter. There are many available (just some links I found -- NOT a recommendation based on personal experience with the products or vendors):

The circuit is very simple, so you could save money and make your own if you have DIY skills:
