guys, masters, gurus, eto po sound setup ko:

94 Honda Civic Hatchback
stock alternator/ ac delco small battery

pioneer in-dash cd/mp3 player
targa x-series 6" fronts and 2" tweeters
macrom crossovers
overdrive 800w, 4ch amp
12" aura sub in an abc box

very basic ito right? am i supposed to encounter problems after this setup? ganito po kase nangyayari:

1. pag umaga, everything works great
2. pag gabi, naka-on lahat ng lights, namamatay ang amp at stereo at humihina ang headlights ko.
3. when i turn off the aircon, ayos na sounds, pero mahina headlights.
4. when i rev up, lumalakas ang ilaw, tapos mag-o-on ang sounds then off ulit after rev drops.

sabi sakin normally kaya daw ng stock alternator ng hatchback ang basic setup na yan. so, anong problem? battery ko is new. alternator daw baka mababa ang charge rate.

eto po questions ko:

1. kelangan ko ba mag-upgrade ng higher amp na alternator? magkano yung amp at magkano pakabit? (may conversion pa right?) ilang amps? at kasya ba sa hatchback?

2. ok na ba yung stock alternator ng hatchback? bili nalang sana ako ng same type as stock. para wala ng babaguhin. (mas mura ba to?)

3. or mag-dagdag ako ng 2nd battery? magkano to? (re wire, kabit, etc.)

important po sakin ang price kung ano mas mura, ok na ko dun. i dont think kelangan ng higher amp alternator for that basic setup. sabi sakin charge rate daw ang i-check kase mabilis ma-drain ang batt. ano po suggestions nyo?
