Can anyone tell me what size harley use for front speakers.........size and watts

Cheers in advance

Cheers guys......My head unit works great and i can hear the music fine, But when i pump it up, just over half way the right side speaker starts flapping. So i thought if i get bigger watts, it should fix it........fingers crossed

   anyone else out there interested in purchasing an upgrade to their sound system?

   i have been in touch with" jacks stereo" in the US  for biktronics gear ,[ as per mals suggestion]

 and he has quoted me   titan 75 watt amp

                                              2  titan hertz 5.25" speakers

                                            for $ 598.09  USD

                                              or

                                           titan 180 watt amp

                                            2  titan hertz 6.5" speakers

                                             for $758.00 USD

    plus around $70 USD freight

  he reckons that he can give a better price if 2 or more people buy one of the kits

   i am keen to upgrade my harmon kardon radio thats fitted to my 09 electraglide standard but as you can see this gear aint  cheap

      open to any other suggestions?

                cheers
