speaker system buying guide image
box_eatjj
Can i hook up an audio system to a stock audio system? If so, how do you do it? What will i have to buy? I'm willing to pay whatever. The car i want to do this on is a stock 454 1990 Chevy SS. Will i have to go "Big 3" and what will i have to buy to make this possible? Would i have to buy an extra battery, a new alternator, and a capacitor or just one of these?
Answer
You will need a LOC (Line-Out Converter) to convert the high-level speaker signal to low-level RCA signal to the amp(s).
If your total system power is 1200 watts RMS or more, you will need to:
1. Upgrade the alternator to a high output alternator
2. Upgrade to a yellow top battery
3. Install the "Big 3" with at least 2 AWG wire.
Failure to do this will result in the early death of the alternator as it will eventually fail.
Here is a guide that will calculate what size alternator and power wires you need http://www.box.net/shared/uchv4dbk88
You will need Microsoft Excel. If you don't have Excel, use this link http://www.box.net/shared/nkkw1dhk4g
A second battery is never a good idea as it's an added strain on the alternator to charge two batteries AND supply power for the car. The ONLY time a second battery is useful is if the audio system is to be used with the car off.
A capacitor is only good so far as the audio system isn't trying to pull too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing else. If the current isn't there, a cap won't help.
The alternator must have at least 20% more amperage power than the entire vehicle and sound system combined for a cap to be of benefit which is ironically the same requirements for an amp to be efficient.

Unfortunately it's not like a light bulb, you might choose a light bulb based on how well light you want the room but audio doesn't work that way. In audio, wattage isn't a measure of... well, anything. Depending on numerous other factors, a certain amount of amplifier wattage may be required to achieve a certain goal but wattage itself doesn't directly correlate with how much sound or how big a room the sound will fill.
There isn't enough information in your question for anyone to give you any useable response. Define "small hall", and define "big one". There are standard reference levels for movies so you can use this to define your goal at least making the problem a little better defined. Most home theatre systems will not reach reference levels however so depending on your definition of what is satisfactory you may not need reference levels.
If you can define the level of performance you want and you can provide information on the room dimensions and details then suggestions can be made that might satisfy your needs. Arbitrary suggestions of various receivers etc doesn't really do you any good.
