I'm looking for an explanation of the advantages of a large trunk battery vs. a HO alternator.
Iv'e done alot of research, and from what I understand- A battery is just a large reserve that may help with quick voltage drops that an alternator cannot respond quickly enough to.
So, on long, extended bass notes, would a large trunk battery help at all with voltage drops? Or on these types of notes is the power coming straight from the alternator?
I dont' really have a dimming problem, but I do have large voltage drops on the long, extended bass lines (11.0 with headlights/AC on). Iv'e currently got a small trunk battery (20ah) and an 80 amp alt/big 3.
I KNOW the best thing to do would be the alternator, but frankly there's no way in hell I can afford one- they're extremely pricey for my car (4cylinder accord).
Would a battery help at all for my specific situation? I can get an hc1800 for very cheap, so i'm thinking of picking one up. And as a side question, would I be better off using it as a trunk battery on top of my crappy interstate starting battery, or replacing my starting battery completely and using the hc1800 underhood?
