Car audio My amp is a "Logic soundlab PLX52" and I can't find it any where on the web. Is it the PLX500 cause thats as close as I can find. Can I search using serial # i've got it?

Here are some reasons that can cause your amplifier to overheat:

• Amp Gains are set to high / Clipping occurs
• Amp is not stable at the ILP (Impedance Load Presented)
• Amp is placed in a poorly vented area
• Amp is a POS or is defective.

All amp's are typically warn, but they should not burn to the touch, that is too hot.

first disconnect one wire at a time, making sure the power is off. then connect power and check to see if your speakers are making the popping sound. when you do your speakers, make sure you disconnect both positive and negitive of each speaker at one time. when your amp goes out of protect mode you will have found your suspect wire. then trace to the issue. it could be as simple as crossed over possitive and negitive wires
cheers

fuses aren't rated by watts.

does it have sound if not it may be on a protect or themal mode try taking our=t your main fuse when the system is in and put it back in

maybe the return address is an outsourced repair shop that has gone bust
contact the manufacturer headquarters and make a lot of noise about the service and ask for a new unit under warranty

Hello lucky33irish,

If it is just the plug that is broken, it's a rather easy fix. Just solder on a new plug. Look closely at the old one to make sure that you match up the wires correctly. You can get replacement plugs at Radio Shack or try this web site. I like the Switchcraft 3502. It's very durable and easy to work with.

A better fix would be to replace the cables with a new set of RCA's.

If the pin from the old plug is broken off inside the jack, you'll need to remove it. I usually start with a scratch awl and gently pry the old pin backwards until I can get ahold of it with a pair of needle nose pliers. Just be careful that you don't push it in deeper.

Anyway, hope this helps.

There are two 40 amp fuses in the unit I have.

Amps can be rated based on their RMS power or their peak power. In this case, the amp's rated RMS power is 300x2 at 2 ohms (total 600W RMS) with a peak power rating of 600x2 (1200W peak). For the most part, peak power means almost nothing.

If your head unit didn't have RCA preamp outputs, you would used the standard speaker outputs from the head unit and connect them to the hi input plug of the amp.

bad ground make sure you have a really good ground
