I know this might sound like a strange question but how do the OEM radios sound with aftermarket speakers ? I put four new Pioneer speakers in my wagon since I was planning on using one of the Alpine stereos that I had in the cabinet. After looking at the mounting options I started to wonder if I should try to find a decent stock radio. Ive been on good terms with the owner of a local yard so I know I could get an original radio for a decent price. Hes got a bunch of Blazers and a few full size GM cars in the yard. Im sure the Caprice Classic that I pulled my steering wheel out of had a nice radio. What other GM cars had radios that would work ? Would they work with the speakers ? Opinions or advice ??
