Trunk battery vs. HO alternator

Just an update- decided to install my hc1800.

It helps alot- previously my voltages would drop to 11.0 with headlights on and AC on full. Now, it wont' dip below 11.7.

With ac/lights off, it's 12.5+.

 
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?

Thanks!
Same boat here... 98 Accord 4 cyl. The best alt you can even get is only a 140A rebuilt Denso unit and it's expensive //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
Ontop of that, I've got a 2200W rms amp in the mail, we'll see how it goes with stock alt, stock batt, and stock alt wiring //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
yo for u with the 98 accord here's a alt. http://powerbastards.com/products.asp?cat=86
