I just picked up an empty 4x8 for free on craigslist but it's completely empty. I was wondering what 8" speakers would work and sound good in it. All I know about the speakers that it came with is that they were stamped SLM and 50 watts. I think it will be pretty impossible to find the stock ones so it's definitely gonna have to be a replacement speaker ie eminence or something. Any help with this would be much appreciated.
