Dual Batteries
I have a 71 bug with 2 12 inch subs running off a 5500watt amp with 4 6.5 inch speakers. I want to get some neons both inside and outside of the car.
At the moment if i turn the stereo up at night witht the lights i all my lights dim with the music.
How can i stp this and would setting up a second battery be an option. Obviously the neons would only be for at shows but i wanna be able to show em
off around town.
Your help is appreiated.

You need an alternator...
to replace Your generator...
Neons won't make all that difference powerwise...
its the amplifiers that use all the power...
I don't use an amplifier... the standard JVC unit is loud enough for me...
If I turn the standard CD player in My Lancer up loud
the interior light fluctuates with the sound...
this was without the engine running...

My celica has a 12 month old alternator in it, i have a factory guage for it, and despite with the music loud and only a 280 watt sub amp, the
headlights and lights in the guage cluster flicker.
its done it for ages now, and the battery still chargers, just the guage dips/bounces with the beat, while still being above the 14 volt mark. Only i
seem to notice though, it couldn't be that bad to the other drivers after tailing a friend up the m1 home for 50 mins with it strobing and them not
knowing what i was talking about.
It does get a little annoying though.

Does anyone sell alternators with higher output than standard that are a direct replacement for the standard units?

i think you will find thats a typo 
my old install was only 1500W in total and was 3.7dB louder than a jumbo jet
5500w could send a bug into orbit
Cam, you can get 75amp alternators from most vw suppliers
i think even 90s are availble from the US
ive never had a problem with the stock 50amp not being suffeint

Apologies for hijacking this thread, but my generator light is dimly lit when I have the headlights on, so I was wondering if it was up the task is I
added a bunch of other electrical gear, which is planned for down the track.
FYI I have a 76 Beetle presumably with a stock alternator.

Get a capacitor.They keep the voltage up to the amp so it will put out less distortion.Less voltage = more distortion at lower volume levels.
59 beetle,61 beetle,72 dual cab,58 beetle,55 splitty,
65 manx,74 camper,60 Rat beetle.....and many more to come
