I just bought a Pioneer DEH-2000MP and when I started to read the installation, it said I need 50 watt speakers, now i checked my factory speakers and there only 15 watts, I have a 1994 Toyota Camry. When I bought the car it had an aftermarket deck already installed, but its one of those cheap Walmart brands, So my question is if i have to upgrade my speakers or not, and if i dont what is the worse that could happen?
i agree, your factory speakers will hold up just fine. eventually they will probiably blow but thats a while off still. the deck says you 5need 50 watt speakers but thats peak you probiably need around an 18 watt rms speaker and the 15 watts on your stock speakers is the rms rating so there pretty close to being perfect for each other!
Go ahead and install it. Your factory speakers should hold up just fine. If they do blow, then you'll know you need new speakers.
