You need better speakers, and you may not have your current ones wired correctly. If the speakers are not connected + and - in sync, they cancel each other out.
Hi, I have the MRC Symphony 77 sound system. It has a good selection of sounds but it is tinny and there is no control of sound volume for specific sounds. The rail clack for example is very soft and if you get it loud enough to hear it well the other sounds are distorting the speakers.
What do you use?
