So my budget is about as low as it gets. What are the best speakers out there for cheap?

You need to be a lil more specific are you looking for 8,10,12,15 in. subs. Door speakers It would be a lil more helpful and how low is the budget cuz you gotta thing amp and wiring also.

I just need to replace my stock speakers for now. I read somewhere that they were 6 1/2's. My budget is $150

Dude you can pick up a pair of 6 1/2's for like 40 to 60 bucks. Anything that you've heard of will work. I put xplods in my truck and they do just fine only paid forty for em'
