I work at Best buy. I know a lot about car-fi. I know that every head unit we keep on display uses MOSFET amplifiers to keep it cool, cheap, and small. These mosfets put out on average 14 watts/channel and at most 20 watts/channel. Everyone knows to get better quality/louder volumes you need to utilize the preouts on the back of the headunit. By then quality will be dictated by the amp you use, and a sufficient power source. Cool.
So this guy tells me I know nothing because I say a sony will sound the same as a kenwood and pioneer and jvc etc. Because theyre all chinese mosfet amps. And because youre putting it in a '98 ford f150 with road noise and engine noise and $40 reinforced paper pioneer speakers. I told him the only differences are the sales they happen to be on, bluetooth capabilities, sirius, hd radio, usb, analog, and the ease of EQ settings. I firmly believe that radios are all capable of the same quality sound out of the box. And he told my manager to fire me.
So, my questions are for the car audio masters, I want to know
WHO makes these mosfet amps. Is it all brand X amps in brand Y head units? Or is it actually sony amp in sony head unit?
WHAT are the differences between brands? Are there notable digital samplers going on behind the scenes that nobody knows about?
IS there ever an argument to take seriously when someone wants sq from the speaker outputs at 15-20 watts? IMO you are going to distort by the time it is loud enough to drown out road noise.
