Good day all, I am new to the forum and a relative beginner to DIY audio overall. Sorry if this should be in the Source and Line section....
I have a probably fairly simple project I'd like to undertake, but there are some random info that I don't know, and perhaps some other info I don't know that I don't know. Here goes that info, in the form of a question:
I have a Vox amPlug 2 (Brian May version) guitar headphone amplifier. In normal use, you plug it into a 6.35mm electric guitar input and jam a 3.5mm to headphones in the headphone output. Boom, instant rock star, no need to wake the neighbors.
Also available is the the Vox amPlug 2 Cabinet Powered Speaker Cabinet, a 2-watt beast with a massive 3" speaker, with 6.35mm guitar input and 3.5mm aux input, running on 9V or 9V DC power supply. So, according to the manual, you simply run a 3.5mm from the amPlug (instead of going to headphones) out to the aux in on the cabinet.
Ultimately, I want a replication or estimation of this cabinet. I don't need the guitar input necessarily, and I have various sized speakers (2", 3", 6", and a pair of Sony bookshelf speakers).... I just don't know if I would need a preamp or a power amp or just a buffer. Should I see if the amPlug itself will drive a speaker first? This would be a consumer line level signal from amPlug to the cabinet, correct? Would that signal be too great for an LM386 build? Is it as simple as that?
I feel like the longer I type, the further I'm getting from my thesis....I will go away now and tinker around, and come back with any findings and perhaps a clearer mind. Thanks in advance!!

So I found this circuit below surfing the world wide web. I don't know if it's an exact copy but it looks a lot like the schematic in the LM386 datasheet.....I think my regular use of a 1/4-watt, 2.5" speaker while testing circuits may have had me thinking I was doing something wrong when building. I tried a couple different speakers today - that's what it's SUPPOSED to sound like!!!
