My friend need help

here's what my friend says happens to his system:

at high volumes, i get a quick "pop" and my whole sound goes out. i turn off my head unit, and turn it back on, and the music is back. this only happens at high volumes. 18+ on my alpine hu. i thought i could've been that i overpowered the amp, so i changed the settings, and i still get the same problem at the same volume. has this happened to anyone? any suggestions? its really scary hearing that stuff because i put so much money into my system. please help.

Sub Amp: PPI PCX-1250 Mono(not installed yet)
Capacitor: Stinger 1 farad cap
Wiring/Accessories:

I would try doing a quick head unit swap. Alpines don't usually go bad, so that is a bit strange. Keep us posted, as I am interested in the resolution of this problem.

Could you be overheating the amp? Is it after running the car for a while?

by **Peter** » Sat Mar 01, 2003 5:36 pm

he said it happens when his volume hits around 20 and he turned down the amp gains and the same thing happens. i think its the head unit, but not sure.

Wait, I'm confused. Is it on your car, or on your friends car. Were the stats that you listed for your car or your friends?

I think when those amps heat up too much they should just shut down. That is what mine do if they get too hot. The pop could originate in the head and be carried by the RCAs. Just a theory, but plausible I think. Maybe the head unit is getting too hot?

you have a voltage drop somewhere in the line. it can be several things, first, did he wire the alpine to the battery?, do all of his amps have the proper fusing, and then check the voltage on the battery and then the alt. :cry:

Gunman to the rescue

On the Alpines they need like 10 gauge wiring directly to the battery. That just gives you an idea how much power they are pulling

i helped him do the install. i did it exactly like mine. our setup is almost identical expect the speakers. mine has been working great, i dont know why his would do this...

gunman, when i check the volt, what should it read? and how do i check it? while its running?

I would assume you are going to use a continunity tester or a DMM (Digital Mutli Meter). Just turn the system on and attach the red lead on the DMM to the power wires and black to the ground. You should be running anywhere from 13.4-14.1 volts. Around 13.8 is normal for driving with a light load, but i have run as high as 14.1volts. You don't want anything over 14.4 and chances are, you won't even come near that.

Hey Peter, did you guys get this problem worked out? Did the proper power run fix it?

by **Peter** » Tue Mar 04, 2003 11:05 pm

he's tryin to get his uncle to test the voltage. we'll see what happens
