I currently have a 900w pioneer amp running my 2 comps. I have another pioneer amp (760w) that I'm not using but wanted to add to the battery to run 2 more sub's. I talked to a guy a a shop if I could do this and he said I would need a HOalt, another battery, and a bunch of other stuff if I wanted it to work and that my batt and alt couldn't handle another amp. Is this true or is he trying to sell me more stuff.
2010 ford focus with brand new oem apt
2 kicker comp 12s in ported box
900w pioneer amp with 4 (yes 4) fans on it
Any help would be appreciated
I asked this same question a few days ago but this is with new input from a "shop expert" so I figured I would ask it again
