I have a 76 and wondered if these alternators are up to the task of running amps or is it more likely my grounds.
The audio sounds ok when the engine isnt running and is ok for about 15 minutes running, then gets a static sound. No whining, but more like a bad radio signal. RCA's run down the opposite side of the car from the speaker wires.
Only one amp is hooked up right now. It's an alpine 4 channel 100watt rms x4.
2 guage runs to a distribution block and then 2 4 guage runs to the trunk. Block is at the firewall.
I posted this in electronics section a few days ago, but things seem pretty slow there. No replies.
Thanks for any ideas.
One of my friends had a similar problem many years ago, here in europe...
Not in a camaro, ok....
It was a bad ground connection.
Try putting a wire from the ground of the amplifier to the negative of battery. If it works ok is the bad ground connection.

Figured I had good ground, but maybe not. I'll have to find some time to mess around it more.
I dont listen to it much in a 4 gear car anyway, but when I hit the highway it would be nice.
Everything worked perfectly in the shop over the winter just hooked to a battery. As the battery got low, I got the same sound. Hook up th charger and it was right back to good sound.
There's a new battery in the car and it's taking a full charge, so ground is where I'll start. Cheaper than an alternator. lol
I wont be listening to it often because I like to hear my car, but I have an Alpine m605-400rms x1 and a mrv345 4 channel-75rms x4.
I've installed many stereo's without any real tech knowledge but this is starting to annoy me. Everything is fine while the vehicle isnt running. 15 minutes into running and it goes for a crap. I swapped the grounds and still have the same issue.
Is there a junk yard upgrade I can grab for an alternator? Bolt in?
I have a 3 wire alternator and am looking for a cheap fix as I have other priorities for the car. It's new to me.
Also, can I run a 0 guage wire straight to the alternator from power on the battery? Leaving th power to the starter obviously. Will it aid in charging the battery? I did what is referred to as the "big three" on my 93 chevy truck and wondered if there is a simular upgrade for the Camaro
yeah a third gen 105 amp alt is a bolt in, from a pre-serpentine belt car (pre 1988 I think). you just swap out the multi rib pulley for your v belt pulley and wire it accordingly for a CS series upgrade
Holy moly Ace, He doesnt need but around a 100 amp alt. He's not running 4 15" subs!!! lol Batt should last awhile with a 100 amp alt. The original is 60 amp I believe on my 73 no A/C. not sure if it was different with A/C. I ended up going 100amp when I bought the camaro.
If I go the junk yard route, I'll make sure I get the connector and hard wire it to the existing harness.
Will the fuseable link have to upgraded or will it be ok?
Shyte...I'll have to look around the wire pile. I bought a 350 last year just because it was cheap and it was complete with alternator and starter. Parted it out, but I still have the harness somewhere.
Without having fuel injection, with every option in the car on (headlights, rear window def., heater blower full blast, and the stereo at full tilt) I'd go out on a limb and say you might actually need a larger alternator than the stock 60 amp if that amp is a 100 watt x 4 channel amplifier.
If not, and it's only 25 watts x 4 channels, no worries. The stock 60 amp will be fine.
