So, I have this idea that I want to try out but I'm having a hard to finding info on it. Basically, I have a hardshell briefcase I used to use for work but since I changed to using a laptop, I no longer need it and it has been re-purposed to store my guitar cables, tabs/practice aids, tuner and anything that doesn't fit in the gig bag. I want to mount an amp and speaker to the side of it, flush mount as best as I can for practising or playing with headphones mostly because I don't want to lug my amp around the house, also so I can play when I'm out camping or at a business conference interstate. I want to open my briefcase, take out a cable, close the case, plug into the jack mounted on the front of the case, fiddle with the EQ/volume and play. A speaker around 6" would be ideal size, can even do 2 speakers around 5/6" but I don't know how to go about doing this. The depth I have to work with is not a lot. One idea was that I could find a portable battery powered combo and pull it apart, mount the components how I want them to the case wall (I can solder longer wires to any components that need it) Can anyone recommend a small bass amp that might work for this purpose? I have looked at the VOX pathfinder 10 bass, but I have a feeling that might be too deep for my application. I'm not looking for amazing sound, just a decent bass tone with basic EQ, volume and headphones out if possible. Running on some sort of battery power. Does anyone have any experience in doing this or pulling apart mini amps in general?
