Just like the title says, guys, I'm getting a vintage radio (haven't found on yet, going to a swapmeet and getting whatever 12v AM will fit my dash) and I'm pretty sure anything close to early to mid 50s (only thing big enough for my dash!) will only have one speaker. Do I need an amp to hook up my extra speakers? I have 4 JBLs that are already in the car, just need wired up again. I have a 2 channel amp, but if I need to get some of those tiny foreign amps or something I wouldn't mind. 2 6x9s in the back and what looks like 2 6 inch ones in front. Thanks for any help!
