My rear strereo home speakers make a clicking noise

Either that speaker is not connected or, the speaker is blown. To test: Disconnect that speaker from the stereo and, using a 9volt battery, tap the speaker's + and - to the battery's + and -. You should hear a "pop". That would indicate that the speaker works. DO NOT connect the 9 volt battery to the stereo side of the speaker wire!!!!

do you get sound from both speakers in mono mode? but no sound from either speaker in stereo mode?

bad soldering on the stereo/mono switch

Check your connections and the settings in the menu.


Good luck

Thank you for using FixYa, have a nice day.

Hello.... I am sorry to hear you are having problems. The reason for this is that since you have a stock stereo, the shop (or person) whom installed the amp and subs used a line out converter. What this part does is allows the connection of RCA cables to the factory head unit. Almost all bass signals are always in stereo, so since you were only hooking an amplifier for just subs, you can actually just connect to just one of the rear speakers instead of connecting to the right and left. Just makes the install a little quicker. There is nothing wrong with this as I usually do the same thing in our shop. However, if you are going to be using the balance control, then you will need to go back to the shop and have them hook the converter up in stereo (to both rear speakers). Hope this helps!

you have to have it set to one of the sound settings to get surround sound , and if what you have hooked up does not have a digital connection ( optical or coax) you can not get dolby digital surround either
if it is the stereo your listening to then set a sound to get virtual surround sound ( unless you have a digital tuner that supports digital signal input

Wire outputs from CD player into inputs of Equalizer, then connect outputs of equalizer to inputs of amp, then output of amp to speakers. Use the best wire possible for all connections, i.e. Monster cables ect.

Please post ratings for all solutions please.
