i have a sony stero system str-k502p and i was wondering if it could handle 4 ohms. if yes explain.?

Question

i was wondering because i was going to put two 8 ohm speakers in parallel with each other which is 4 ohms on the 2 rear channels. I wasent to sure if the unit could handle 4 ohms and not get to hot, if you can answer my question and explain why, or throw some ideas at me i would appreciate it thank you

Answer 1

Rear channel speakers do not carry a lot of power, and you are unlikely to run into an overload problem with 4-ohm speakers. If you are worried, connect the speakers in series, maintaining proper polarity (amp red to 1st speaker red, 1st speaker black to 2nd speaker red, 2nd speaker black to amp black). You will lose a little power capability as the amp drives a higer impedance, but just make up for it by increasing the rear speaker level. (You should do this by re-balancing your system with the test tones.) You have to be careful when adding speakers: make sure they are matched, ideally the exact same speaker. If one speaker is much more sensitive than the other, that's the only one you'll hear. This applies whether the speakers are connected in parallel or series.

Answer 2

Your Sony receiver is not capable of handling the ohm load because it is not designed as a high current amplifier. Unless you have a switch that can select it don't do it then on top of that if it has a switch still read the precaution most of the time its only the front main speakers that work off of the switch. Just break down and get a real 7.1 theyare very cheap now a days
