I have a 1999 ford ranger. I have replaced the stock speakers with 2 pioneer four-inch round speakers and 2 sony five-by-seven speakers. I want to put a 300 watt amp on them for a clearer, crisper, louder sound. I don't want to put a subwoofer in my truck. Do you have advice on how to go about it? Or if this would blow my speakers? Thanks a lot!
