Portable Amplifier

Step 2 Wiring things up.

Once you've collected all your materials, go ahead and dismantle your entire amp. There are lots of screws, if you don't know which ones need to come out, take them all out. Just make sure you keep them separate, so you can put it back together later if you so choose.

Now, this amp in particular, takes a 120V current from the houseline, and steps it down to 13v for use with the amp. However, I am lazy, and don't really care what happens to this amp, so we're just going to completely bypass the stepdown converter, and hook up a sheer 18v directly to the mainboard. It's all solid state, so the worst that'll happen is a battery might explode, or you'll burn out the ICs. Hope you don't want this amp anymore.

So, basically, what we'll do, is wire the two batteries in a series, attach the negative to the mainboard, and the positive to a switch (because we're bypassing the built in switch). And that's pretty much it, as far as wiring goes. To wire two batteries in a series, attach one positive terminal to the other's negative, and then use the free positive and negative terminals to attach to your actual destination. I find that the little 9v battery clips are the easiest way to do them, although I could only find one of them when I did this project.
