Once again I'll expose the soft underbelly of my techno-doofus-ness. Is it okay to take one instrument cable coming out of my bass and run it through 2 amps? What is the recommended device to split the signal? What precautions should I take to keep from frying something? What are the other questions (preferably, with answers) that I don't even know to ask?

I would suggest running into one amp and then taking the LINE OUT of the first one and bring it into the INPUT of the second rather than trying to split the signal out of the bass. The only caution is that the signal output of the LINE OUT may be quite high, so you might have start with the volume of the second amp lower or need to put it into a -10db jack if the amp has that available. Another setup I use regularly is taking the output of a stereo chorus pedal or stereo digital delay and sending each output of the pedal (L and R) to a different amp. It's a reasonable question. Good luck, but just do NOT under any circumstances take a SPEAKER OUT and bring it into another amp input. Hope this helps. I use multiple small amplifiers all the time (one as front monitor, one in rear near the drummer) to save my back from lugging around monster 8x10's. You actually might end up with the same sound level as a huge rig. It also keeps the stage volume under control. Good luck experimenting.

I'm getting pretty good at answering questions with questions, so here goes...
Do you already have gear that you're trying to make work together? If so, what do you have? If not, what is your goal? It may be that multiple amps isn't the best/only way to get there.

There shouldn't be any problem, really, with just splitting your bass signal with a simple y-connection. If what you want is some separation, sonically - ie an amp on either side of a stage, this can work. Unless you are looking for something more complicated, like stereo output, then you are probably fine. But then, you would be fine with two cabs as well, as long as you were watchful of the impedance issues. As Bob suggests (inferentially, by his deft Socratic method), it all depends on what you want, and of course the result will be dependant on the amps you are using.

Thanks, Jim Bob (Y'all from Texas?) and Rick. It seems to work just fine. The 2 combo amps I am using are a GK Backline 100W 112 and a GK 700RB 115. Yes, Bob, the goal is to use what I have. I love collecting gear but I really don't want to buy something that I don't really need.
I plugged the bass into the 112, and the line out into the 700 (-14db on). I'll try it the other way around sometime. It sounded pretty good with the bass down a bit on the 112. I could run it quite a bit louder without so much bass. The 700 really honks on the low end. Maybe some day I'll add a 210 cab to the 700 but for now this is sounding pretty good.
This tech-know-nothing thanks you.

I am glad that is working for you. I often use my little GK combo to drive a much large amp as a slave, since I like the GK preamp sound, and it works like a charm.

And if you really want to get fancy with your GK combos, in addition to your small stage rig, take the two cannon outputs direct to the board in L/R stereo. Then kick in your internal chorus. Bribe the soundman to backhaul your feed into your front vocal monitor and the side-fills. Magnificent!

I've used 2 amps for a long time (now only when I feel like carrying things).
I started out using the stereo outs on my Ric, each pickup to its own amp.
Nowdays I've been using a Morley A/B box to split the signal from my Excel and send an out to 2 seperate amps, each EQ'd differently, you can also run seperate effects to each. Its nice to be able to switch between and/or combine the 2 amps.
