OK so I got a new car..put my CD player in and when turned up at all the speakers would pop and distort like crazy..so I figured they were blown I bought a set of JL components (Iknow) and they were too deep to be mounted without too much fuss and they sounded like shit.. I go return those and bought a set of Boston Acoustics and have them installed at teh shop... when I listen to it at any loud volume they distort and pop like the old factory...the shop said my HU's internal amp might be bad and recommended I get a replacement.. I buy new HU and it still distorts and sounds like shit... So now I'm thinking that it is the wiring...could wiring cause this kind of problem.. Sorry for the long post...thanks in advance.
