So, my car is still new, and I REALLY don't want to drill into it for any reason. For the time being, I'd like to keep the factory alternator (110A, still under warranty). So, as far as upgrades go for the electrical system, I'm ok with "big 3" and adding a battery in the trunk, buuuuut I don't wanna drill into the trunk to mount it. Is it taboo to mount a small-ish AGM battery to the side of the sub box? I feel like this is wrong, but I can't quite put into words why it would be if it's mounted well. The amp will be a soundqubed q1-2200d with the gain set back to 1400W-ish.
