Hello tonytone54, The ground should go directly to the vehicle frame, never through a cap, fuse, or anything else. Also, if you are connecting positive through a cap, make sure that you charge the cap before connecting it. Hope this helps.

Transistors burning or getting hot small yellow non polorized filters in the out put area swollen(6)


there could be a list of problems... for one make sure you are using a ground cable 4awg or bigger and no more than 18 inches long this must be bolted to the body tight and a clean metal to metal connection. the ground must be the same size or bigger than your power wire. you should have at least a 150 amp altinator and a single dry cell battery. i use drycell to keep corrosion away. the longer your power cable the bigger it should be. at 20 feet you should run a 1/0 gauge power cable at least to a distribution block with the correct size to the amp. if your using a cap all cables must be the same size with the ground same size or bigger.

Ran it at 1@ now it has low power


Hello if your amp is the one above in the picture, MTX-1501D then your amp is not 1 ohm stable. Your amp is rated at 500 watts x 1 at 4 ohms and 1000 watts x 1 at 2 ohms. The amp has a safety circuit that if it senses to low of a load, ohms, it will only put out half it's power to protect the amp from shorting out. Read the manual. You can download it at retrevo.com or just google it and a manual download site will be in the search list. Hope this hels, Good luck.

if your power light is on then check your preamps (sub out from head-unit).Maybe you need to turn on that output thru head unit's audio menu.Also when using dual voice coils if you wire them out of phase there will be no output

There are a lot of problems that can cause the amp to apply DC to the speaker terminals.

Before we go any farther, you should know that this amp stores enough energy to kill. When power is applied, the transistors must be clamped to the sink. After removing power, you MUST wait for ALL LEDs to go COMPLETELY out.

You need to CAREFULLY measure the DC voltage from leg 1 to leg 3 of all of the output transistors (the ones you changed). Post a list of the voltages and circuit board designation (FETxyz) for any that read more than 1v.

Do NOT let the probes short to other pins or to the heatsink when measuring the voltage.

Remember... High voltage and lots of stored energy. Be careful.

Amp problem


These amps have a problem with broken shield connections on the RCA jacks. If the shield breaks loose from the frame of the RCA jack, you will have this problem. If you disconnect the amp from power and pull the cover, you can check to see if the shield is loose in the frame. if it is, it needs to be soldered.



You can also have this problem if the shield ground opens on the head unit.
