Hello,
First of all, I have to say that I have absolutely no experience in the audio world, so some questions may seem like I have no idea what I'm talking about. However my job is in the electrical engineering, so things like resistance, impedance and voltage are things that I'm familiar with.
I have a Dodge pickup from 1977, and it's audio system has seen better days. The previous owner put an OSIO HPA4000 amplifier into it, and a pretty old subwoofer, which still works fine. In both doors are 6x9" speakers installed (I think they are 6x9", how do they measure those?). And in the dashboard there are two small tweeters.
I want to replace the two door mounted speakers because the cone is cracked. The problem is that I have no idea how much wattage the new speakers should be.
The amplifier says "150 Watts x 4CH Bridgeable High Power Amplifier" on the top. I have searched through the internet but I can't find any datasheets or something about the amplifier. Right now the audio system is not connected ideally because the tweeters are just put parallel to the 6x9 speakers, and I don't think that the previous owner has looked at the impedance of the speakers or something.
I was not planning on replacing the amplifier so I hope some of you guys can help me to sort out my audio system.
