DIRECT REPLACEMENT 

 

ARC Audio 

speakers are designed to fit most 

applications in the original stock location without 
modification. Some vehicles may require minor 
removal of material and relocation of mounting holes 
to achieve a proper fit.  
 

A WORD ON DISTORTION 

 

Most speaker damage occurs as a result of amplifier 
distortion also known as “Clipping”. Clipping occurs 
when an amp is driven beyond its maximum rated 
output. This kind of distortion can be hard to hear 
unless you know what to listen for. Any time you hear 
a harsh ear piercing sound at high volume your amp 
is probably clipping.
