Amplifier Issues :(

Well, me and my friend both have the same problem with our amps. Whenever we turn it up past a certain level the amp light dimms and all we get is a short thump from the subs every once and a while, but if i turn it down to a certain point my bass is fine, but wheres the fun in that? Can anyone tell me why this is happining to us, are we not getting enough power? and if so why? thanks for any help.

Hard to guess if you don't say what amp, what speakers and how its hooked up.
How long has it been installed, who installed it and did it ever work before?

Sounds like you dropping the impedance of the speakers below what the amp is stable at, tell us what you have for amps and speakers and we should be able to help ya.

sorry for being vauge im new to this, i have the power hooked up to a 12v line wich was used for a light in the glove box(measured with a voltmeter), and the system control hooked up to the 12 volt ignition wire. My equip. is a Pioneer GM 5100T 800w amplifier and 2 10" rockford fosgate subs. hope that helps.

yikes! are you saying that the amps power is run from the power wire used for a light?

thats what i thaught at first but the line for the light and the line for the radio are the same guage and measure the exact same current so really what is the diffrence? would you reccomend using the cig. lighter wire instead? or going threw the hassle of wiring it straight to the battery itself?

When installing any amplifier, you should run a direct fused power line from the battery and make sure you use the proper gauge wire. As it stands my guess is, you more than likely have an 18-14 gauge wire supplying power to the amp...This is not a good thing...What is the fuse rating on your amp??

My first thought too. Ya you need to run minimum 8 Gauge (4 is better) from your battery to your amp fused under the hood using a fuse that is the same rating as the fuses on your amp. Then its fine to use the 12V switch within the car for your remote. DO NOT CONTINUE TO USE IT THIS WAY! you dont want to screw the amp or worst yet cause an electrical fire.

I would not use 10ga, if you want to upgrade you will have to rewire the car again id go straight to at least 4ga its not that expensive and its worth doing.
