it loud? hi yesterday i went to my friends house shut off my car went into his house for about 5 min and came out side and when i turned on my radio is was making a loud weird noise,it sounds alright on like 20 volume but when you turn it loud or their is a bass part it makes a really weird noise.

i cant really tell what it is? im thinking it might be the amplifier in the unit?

i dont have a system,its only a after market radio with after market speakers.

they have worked fine for 2 years now all of a sudden i can listen to the radio without it sounding terrible.
