If I want to run 2 amps, would it be possible to plug the bass into amp 1, then get an XLR-1/4" cable to connect the DI to the input on amp #2? |

If you want the simplest solution and both amps have effect loops (or a pre-amp out and a power amp in), do as Son-of-Bovril says. Plug your bass into tje amp you'll use as the master, and run a guitar cable (NOT a speaker cable) from the pre- out or FX Send on that amp to the power amp in or FX return of the slsve amp. This avoids impedance loading your pickups, gives you only one set of tone controls to deal with, and fewer potential problems.
If you can't do this, then a splitter ox or a mono Y-cord with 1/4" jacks should be OK. A ox or a Y-cord are generally the same electrically; all three jacks are in parallel. That means your PUPs are seeing a different impedance than with one amp. That can change the sound a lot.

Would need to know what the 2 amps are, if they're not identical if you wanted to sound from one fed into the other, or if you wanted to simultaneously blend the differing sounds of the two amps, or switch/toggle between them.
For example, many of the MESA amps provide a pre-EQ DI, post-EQ DI, speaker output powered slave output, FX out, and on and on. Lots of different ways to feed an output signal to some other device, and with different sounds output from the MESA. |

Will this change the impedance loading of the pickup, similar to the ABY box?
