well i got this headunit and a set of Power Acoustik KP-42N... i know cheap.. well they sounded good for a bit but than started to sound like they were blown when ever there would be a thumpy beat in the music. Well i thought it was just because they were cheap speakers.. i than got a set of VIBE audio Slick 50 and they sounded great at the beginning but than they started to have that blown speaker sound at lowish volume. the tweeter than stopped workin and would go on and off.. Meanwhile the Kenwood KFC-6950S i have in the back have been working fine. anyone got any clue what the hell is goin on??
