I have a MTX 1501D, about 5 seconds after I supply power to the amp the 100A fuse will blow and burn up in the distribution block. Which of course cuts the power out to the amp. What can cause this? Me and a friend have been trying things for the past hour and cant find the problem. The amp was working fine about 3 days ago but now this just came out of the blue.
Yeah I figured that, Some how my friend convinced me that it was the best way to wire it. Previously I had it wired going through the firewall then into my car. The coating can touch bare metal right? Its a 4 gauge by the way so it isnt the easiest to cut.
Whoa, you can't be serious right? You can't run a live wire outside the car. You're just asking for trouble. You're lucky nothing shorted out. It could catch fire, especially during hot summer days. All you need is some dried up twig near the power wires when it gets shorted. You know that there's a gas tank under the car right? You've been very lucky thanks to the fuses so far.
Yeah I know. I had a feeling it wasnt good to do but as I said, Friend convinced me(Whos been installing amps and such for 10 years) Thats its best to wire underneath, The hole is still there in the firewall so I'll just rewire it. I'll post back later on when I re-wire it. and see if the problem has been fixed.
As you should be, He does very messy setups anyways. I wired my amps previously with no problem but for some reason I let him wire this one. As I said I'll rewire it, If the problem is still happening I'll try another amp, If the other amp is still cutting out then what could the problem be?
Then it could just be bad amp. It happens. Nothing you can do but get if fixed or replaced. Just so you know, not all MTX amps are good. Some are better than others. I know the older MTX amps used to be pretty good and durable. The new ones, I am not sure. The same thing applies to RF and Kicker. PPI's PC and PCX series amp are very good for the money. They are also made in the US.
If you want to be 100% sure, get a circuit breaker and then attach the amp. This time with a DMM, measure the current flowing to the amp. Most amps with no load will eat up 1A-2A. So if you're getting much more, then the amp is at fault. Do rewire your amp cables properly inside the car.
