Looking for some advice. Bought an 55 plate S-Line a while back. The Symphony stereo unit has a max volume of 30, but when turned up past 18ish when it's playing a track with a reasonable amount of bass, the sound starts to pan in and out. This is with the bass on the equaliser set to zero.
Does this definitely mean my speakers are blown? (or does the head unit have a bass limiter on it that i can't find?!!)
if as presumed, they are blown, i have read that the bose upgrades are very good. if i want to upgrade, do i need to replace all the speakers? lastly - does anyone have a link to where i can buy these?
