Ok, first off i would just like to say that this is my first post, and i am relatively new to the car audio scene, so cut me some slack. My dad and older brother are transmission mechanics, and lately have been giving me a hard time about my truck, a 2000 chevy silverado. They always tell me that i am going to somehow "fry" my computer system by adding too much stereo equipment. my brother says that, by adding things that draw alot of power, my computer isn't getting enough power to operate properly. He says eventually, the whole computer system will melt down or something, leading to transmission failure as well. Today, he told me that if i want to get my vehicle louder, i have to get an older vehicle without a computer system integrated into it. Obviously there are people out there who use new model vehicles and they are much louder than mine. My dad agrees with him, and i really don't know if there is any factual information to back this up. I was wondering if there is someone who has experience with this issue, and if they could weigh in on it. thanks
They probably don't want to see you go deaf. They are making all that up in order to scare you into not damaging your ears.
A cars electrical system is designed to withstand a constantly changing electrical environment.
However, the more of a load you put on the system the harder it can be on electrical components. As long as you do everything the "right" way your risk of damage is minimal.
However, if you add a 5,000 wrms amp and don't upgrade any of the electrical system you're asking for trouble.
The best way to answer your question is to figure out how big your alternator is, how much current your vehicle needs to operate, and how much current you are adding to the system with the addional stereo equipment. As you add more and more current to the system you may need to upgrade your OEM wiring, your battery, and/or your alternator.
I ran a ~1000wrms system off my stock alternator (upgraded battery and wires) for years with no damage to any electronics in the car. Although my speedometer did fail but I think it was more from the constant vibration then the power supply. Just keep in mind that every vehicle is different in regards to the size of the alternator and the headroom between how much current is available and how much current the vechicle needs.

there is no factual information for this. sounds like some people just make things up when they dont understand them. the worst thing you can do if your not upgraded like Kpierson stated is tax your alternator until it finally gives out and you need a new one, that and batteries. your not going "to fry a computer" or "cause a meltdown", that is crazy talk.
