If it happens to be lower when I first get in my car, once I make a stop then restart my car it is normally back to normal. However as I am driving it will sometimes lose output. Both the sub and amp are a few years old but have both been taken good care of. The gain is hardy open and I do no play the system very loud. Any ideas on what may be going on and any tests I could run to see if maybe the amp or sub is going out? |

Also make sure everything is grounded solidly and connected firmly. Do you have an older battery and are you making enough power?! MY 500/1 is 6 years old almost and runs as perfectly as the day i bought it. |

Post Number: 171 Registered: Jan-08 | The head unit is an Alpine CDA-9827. here's a link with the specs. http://www.crutchfield.com/p_500CDA9827/Alpine-CDA-9827.html?tp=5684&tab=feature s_and_specs The preamp out volts are 4 volts and everything is connected securely. I made sure to do a good job when I ran all of the wires. The battery is a Optima red top that pushes a little more than its rated. One thing I do have is a 5 farad stinger cap. Would that maybe have something to do with it? My 4 channel amp doesnt seem to have any change in its output just the sub amp. It just started doing it in the last couple months. I found that if I turn the subwoofer output on my HU to +5 it makes up the difference and sounds just right. Then when the amp goes back to normal I just set it back to +0. |
