Speaker to amp wiring question (1 Viewer)

Receiver: HT-R540
2 Speakers: JBL SP6CII

Receiver is rated as
120w + 120w (8ohm Front)
170w + 170w (4 ohm, Front)

Speakers are 8 ohm
Speaker spec says: maximum recommended amp power is 80w

Im trying to use this old home theater receiver to power these brand new JBL speakers I just got. I will be using them for music only.

1. Do I put both of these speakers on one wire to get the wattage down to 60 each?
2. Do even need to worry about wattage being way over as long as the ohms are correct?
3. Does the "120w + 120w" mean left and right front?

Thanks!

1) NO NO NO NO NO NEVER NO NO.

In case that wasn’t clear... NO.

There are two channels, left and right. They have to stay as left and right and that can’t happen if you connect one to both speakers. One connection, one speaker. Period.

2) Don’t worry about it.

3) Refer to #2.

Any amplifier can put out anywhere between 0 watts and its maximum rating (120 watts in this case). It’s all done with the volume control. Zero watts in this case would be with the volume control turned all the way down.

Get the picture?

I need to run 40ft of speaker wire to make it to my receiver. Do you all see any issues with that length wire? From the research I've done its right on the edge of being ok so wanted to get some experienced answers.
8 ohms speakers
16 gauge speaker wire

I assume this is for surround speakers? Most agree that 14 ga. wire would be better, but for the past couple of years, for reasons I won’t get into, I’ve been using 18 ga. wire that long or longer for my 4-ohm back surrounds. Not ideal, but it works fine.

Yet, 12ga OFC wire can be found rather cheap. So, why save $20? Doesn’t seem worth it to me.

This is for two in ceiling speaker that are going to go in the living room with the receiver hidden in a utility closet. Just a left and right stereo for music.
I got a great deal on the speakers so im using the speaker wire and receiver from my existing home theater so wire is free:rock:.

Short story: Any suggestion on brand of 12g ofc from Amazon? I found a shorter path and 30-50 total will be more than enough.

Long story: Yall sold me on just buying new wire. I have had to reconfigure my path because I couldn't get through the middle of my house between the floors bc I have a modular home. There is what seems to be a steel plate where they brought the two sides of the house together. I found a much easier path that required me cut an access in the wall of the upstairs (wife was less than thrilled), which is why I didn't go this route in the first place.

Monoprice is always safe. As mentioned, it’s best to use CL2 if it’s going through a wall.
