I need help as well. After about a month of reading the forums, I decided to replace my 2 blown door speakers In my 2004 Crossfire. I left factory everything and from suggestions I have read here, I bought kappas. After installing them my battery would no longer start my car even after I would jump the battery and run the car for awhile. So I bought a new battery and car starts fine. But now I noticed my front speakers will just cut out while the rear factory subs stay on. Than I shut the head unit off than back on and I have sound back for maybe 5 minutes depending on how it feels. Do I need a bigger amp or what is wrong? I love the new kappas sound great when they work ty.
