hi level inputs burns up amp

any other opinions? i cant help but to think that my rear speakers being hooked up as well would cause an amp to burn. i thought they were able to be kept since the amp is only using something less than a volt for the input.

even if that didnt burn it up, having less than 1 volt is not a good thing. the speaker is also going to pull a very inconsistent amount of power when playing music. i think you are making a huge mistake by doing that. your input on the amp might get 500 mv 1 second, then 1.5 volts the next, changing with the demand the music being played requires. im sure the power is extremely erratic with a speaker in the line. and you are 1/2 the signal anyway by only using a single set of wires.

its just that everywhere ive read, the directions never include unhooking the speaker. its considered an inline converter meaning you can keep the speakers hooked up. the 1 volt is the maximum voltage that the rcas are supposed to have. i havent checked mine yet so that was just a blurted out number.

mine are 4 volts for the sub, and 5 for the fronts. 700 mv (.7 volts) of input is the minimum allowed i think for alot of amps. you may be right. it doesnt sound right to me though.

i just read that the conversion on the converters are 10 to one. would polarity of the speaker wires cause something like this to happen? i thought i was careful about that, but i guess im not entirely sure. its just hard for me to believe it would cause the amp to burn.

polarity wouldnt affect the input on the amp i doubt. it plays h3ll on speakers and subs though. you arent burning out the entire amp, just the inputs. the problem lies in the wiring to the inputs in all likelyhood. unhook that speaker and see how it works without it y-d off from the input signal. i bet that solves the problem.

well after further investigation, i found that after the fixed line converter, it reads around 4 volts which seems too high to me. everywhere i read, the line converter is wired into the rear speakers wires and the speaker is not disabled. so i do not plan on doing that. is 4 volts too much? i know hatemonger said his are 4 volts, so thats a little reassuring. i bought another amp and want to hook it up, but would like to be sure that im not going to burn this one up too.

thanks in advance.

also, is it bad to use just one side of the converter? ex. wiring it just to the left speaker. so only one rca has current going to the amp? its a single sub, and a mono amp, so i dont think itd cause an issue

i should note that the voltage reading was not done with a test tone, and the meter was set to dc which from what i read is incorrect. its a digital voltmeter and doesnt jump around like an analog one would, so 4v must kind of be a average?
