I have two outside speakers on my balcony and the speaker cable wasn't long enough, i didn't calculate the lenght so i had to buy extra cable and i put the two together using electrical tape. My question is Do you lose quality on the audio signal by doing this and if you do is it something you can hear? i really couldn't tell the difference because to me the speakers sound "allright".
Can someone give me their honest opinion, without turning this into another speaker wire debate?
What you've done should work fine, but I would suggest using solder or at least wire nuts rather than electrical tape. That stuff is really meant to insulate. That being said, what you've done could last for years, so long as nobody trips over the wires or something.
