So I completely replaced all the oem JBL speakers with Rockford Fosgate speakers and tweaters, 2 Rockford Fosgate 12's, and 2 kicker amps, One to power speakers one to power subs. What upgrades or modifications can I make to my Inverter, hybrid battery, and 12v battery to protect my prius and equipment from failing/damage when I decide to add more audio equipment? I'm trying to keep my rms low atm because I'm afraid going too high will damage the prius Please no posts about why I would want to add any more equipment
