Makes me wish the battery was in the trunk.

Well it could probably be done with a Class D amp. But the Alpine MRP-F240 is an AB amp which is less efficient but is also said to have more rich and accurate sound. That being said I would just feel better personally having at least 8ga wire running back there for power and ground on that one. The Micro amps are class D and have less power requirements/more efficiency than AB or A.
Keep in mind the stock amp is probably pushing around 25w RMS with less advanced crossovers (if any). 40w RMS is an appreciable upgrade as far as power goes.
Edit** I think the Alpine manual recommends 10 gauge wire which means 10 is more than what is required (they wouldn't low ball it)
