Hey i have 2 subs hooked up and when i turn the subs and bass up to a really high point all of a sudden the subs will stop hitting and ill get a muffled noise. Im not sure what this is... overexcursion maybe? Dont worryi make it a point not to let this happen. Oh and they seem perfectly fine other than that. Oh and does it help to use more than one speaker wire from the terminal on the box to the voice coils or does it matter at all?
