Without a big backstory, I'm interested in building an amp that would boost the output of an existing speaker amp.
The idea is that instead of the added componentry, complexity and suboptimal gain structure of attenuating a 15-30W signal down to line level for input to a larger amplifier, only to boost it back up again to 60-120W, this "amp booster" would simply take the roughly 15-30 watts from an existing amp's speaker outputs and triple (or quadruple?) it....no attenuation + redundant amplification needed. Just a simple, smaller "booster amp" with a high-wattage 2-8 ohm input stage.
I'd need something that would run on 12vdc or less.
Does such a thing exist? If not, can anyone recommend a methodology for creating such a thing? Or perhaps some chips or transistors off which to create an input, buffer and amp stage? Spank ya vary mooch!!!
