So my 99 currently has a wierd audio setup going on, thre is a pioneer head unit (pos) and Bose cassette player (doesn't work) in it. The head unit will cut off and back on whenever I try to change the audio source. It'll start working like it should after being on for 5min or so but needless to say I want to change my head unit out for something nicer. My question is whether or not there is a quick/easy way to tell if my car has had a bosectomy done to it already? Im ok with taking the current hu out if need be but what do I look for? Oh and while we are at it any recommendations good 8" speaker replacement? If it helps here is a pic of the setup below. Thx!
