I currently have a 2000 Toyota corolla it has an 80 amp alt. and i was planning on doing the big three and putting a upgraded batt. in. will that be enough to run a hifonics 1500d and an Fi BL 15 @ 1 ohm? another kinda unrelated question realistically how many watts will that hifonics amp be putting out @ 1 ohm? Answers are appreciated. Thanks for your time.
