Hey guys! You know those powered subwoofers you can add to your home theater system? The one I have is a Cerwin Vega AVS-SUB8.
When I had a boombox style Sony stereo I used the speaker terminals to power the subwoofer, and I had some cabinets wired to the outputs. Since I had to replace that stereo I decided to make one with a car radio and an Smps from an old desktop computer.
If I try using the speaker terminals to power the subwoofer with my car radio/stereo, it doesn't work.
If I wire everything up and turn it on my radio doesn't make a sound. If I have the radio on and playing, I can hook up the subwoofer and it works fine. But If I turn the radio off and back on again, my radio won't make a sound. If I then disconnect the subwoofer while the radio is still on and playing (but not making a sound) the sound instantly starts playing again.
If I use the coaxial input it works fine.
The only thing I haven't tried is to use both the speaker terminals and coaxial inputs at the same time.
Could the 50W per channel that my radio makes be too little to power the subwoofer? If that were the case, wouldn't it just be quieter, not silent?
I already opened up the SUB8 and moved the little "jumper" from the (Auto) prongs to the (On) prongs, but that just makes it so the subwoofer doesn't go into sleep mode when the radio shuts off and did not fix the problem.
Also, do the coaxial cables act like speaker wires? By that I mean If I use piggyback coax cables to power several of the same powered subwoofer, either in parallel or series, will that effect ohms or anything? Or what about the same scenario except I use the input/output speaker terminals to power several of the same subwoofers?
Any suggestions will be appreciated!
