Hi All,
This is my first post here. I have a JVC RX-R77 Receiver with specs:
- Output power of 125W per channel (8 Ohms)
- Surround rear channel: 20W per channel (8 Ohms)
- Back layout:
a) Front Speakers 2x2 matrix: Right/Left and Channel 1/2
b) Surround (Rear) speakers: Left/Right

Here are my 8 Ohms speakers:
- Kenwood 100W Center Speaker (consists of 2 50Ws)
- (2) 40W Kenwood Rear Speakers
- (2) 18W tower Fisher (each tower = 10W bass + 5W Medium + 3W treble)
- Norcent 50W Subwoofer
- (5) 4 Ohm tiny Norcent 20W Satellite speakers

If there is no way to connect the speakers to the receiver, please let me know what speakers I need to buy.
I appreciate your help for a newbie like me. Thanks.

What kind of speaker connectors does your receiver have?

Can you post a close-up picture of them?

That is going to be needed to answer your question.

Your speaker connectors are spring clips designed to accept bare stripped wire ends.

Any pair of wires from a speaker will connect; I see no problem.

Use connections labelled 3, 4, 7, and 8 for four speakers, front and rear.

It does not really seem to be set up for effective use of more than four speakers.

The receiver's big exposure is the limited power for the rear channel speakers. However, that is not necessarily a show stopper.

The speaker's big exposures are their limited power handling specs. However, if you restrain your operation of the volume control peace can reign.

The AVR seems to have regular binding post output terminals.

I don't see why you can't attach any speaker you have to any set of terminals on the AVR.

Your speaker collection seems to be thoroughly infiltrated with models that may have questionable sound quality. But if you are a budget or starting out, why not?

Note: This is a rack system and not really comparable with any modern AVR or component speakers. If high sound quality is the goal, starting over may be a good idea.

Front, Back Layout and Specs JVC RX-R77.pdf 335k .pdf file
The problem is my knowledge. I thought the total wattage of the speakers connecting to the receiver have to be 125W. If speaker wattage is greater then the receiver is weak to drive the speakers. If speaker wattage is lesser then the receiver would fry the speakers. With that thinking, I can't find any speaker combination that has total wattage of 125W to connect to one channel of the receiver to form a 2.0 or 2.1 setup. Please enlighten me smile.gif
Yes, I'm on budget right now even though I know the equipment I have suck.
Per attachment, the equalizer in the front of the receiver has separate controls for front and rear speaker.
Thanks.

OK, from the back of the AVR, can I set up like this:
- Front speaker (125W/channel): Left connects to Fisher tower 18W, Right connects to Fisher tower 18W (36W for 1 channel). Is is idiotic to use a combined 36W speakers on a rated 125W channel?
- Rear channel(20W/channel): Left connects to small Kenwood 88dB Rear Speaker 40W, Right connects to small Kenwood 88dB Rear Speaker 40W (in the back of the Kenwood reads "Rear Speaker")
Or I have to do it the other way around: Kenwood ones to front 125W channel, Fisher tower 18W to rear 20W?
Thanks.

Always put your best speakers on the front channels.

Forget about power ratings because at your level, they are only confusing you.

The exposure with putting low wattage rating speakers on a high wattage receiver is that speaker damage is only a certain amount of clockwise rotation of the volume control away. If you can discipline yourself, then the small speakers could live happily forever. If you get three sheets to the wind and wanna dance the night away, I predict disaster!

Frankly, with the speakers you seem to have, if they get fried, I'll shed only a few tears. But you need to figure that out for yourself! ;-)
