Be careful of inputting line-level audio output signals such as a laptop into the Instrument Input of any Spider amp. The best input would be the mp3/CD player input. Line-level signals can be a bit too much for a guitar/instrument level input circuit... please be careful of that.
Regarding the speakers: you can put in alternative speakers... just be sure they're the correct resistance (8 ohms each). A Vintage 30 can be cool, but just keep in mind that the Spider III is a digital modelling amp, so it's not the same as a tube amp driving the Vintage 30. The stock 12" speakers in our modelling amps are actually "flat-response" versus the midrange signature that Vintage 30 or Greenback 25's (for example) are known for.
