SOURCE: MY AMP TURNS ON BUT NO AUDIO OUTPUT TO MY SUBS! I

First, test your sub terminals for an Open connection, or no resistance. This is to test if your sub is blown. This is usually the case.

Double check your wiring, not only to the sub, but from your headunit to your sub. Make sure your headunit is configured to work with your amp, if you have a setting for this (for instance, SUB: ON).

How do I connect a Sony xplod 1000 watt 2 channel amp to 1 10" dual 4 ohm voice coil 1500 watt planet audio subwoofer?


Connect one voice coil to one channel of the amp. Repeat with the other voice coil. Do not bridge the amp as your only choices would be series which would be an 8 ohm final load and cuts the amp power in half or parallel wiring which results in a 2 ohm load and very few Sony amps currently made can handle being bridged to a 2 ohm load.

Sounds like your power supply to the amp. Make sure you location has plenty of air flow around it and use at least 10 gauge wire to the power input. Same size on the ground and make sure all contacts are clean. Your alternator will run hot when the sound is cranked and the car is moving. The heat lowers the amperage output of the alternator and will cause the amp to cut in and out.

How do i wire a solar baric l5 to a planet audio 999w amp?


You should bridge your speaker on the amplifier. Check your connections on your amp. Normally it will be the - (Minus) on the left channel and the + (positive) on the right channel

No sound out of it, took it apart and found one of the Irfz44n mosfets burned up and the resistor right beside it burned too, What would cause this?Thanks


Hello rjhunting,

Most often the output MOSFET's and associated circuitry will burn out when the amp draws excessive current. And excessive current draw is most often caused by operating the amp into an impedance that is too low. Of course, depending on the age and actual use, the amp could have failed from normal use. The US Acoustics USX-4085 is a relatively good quality low-end amp that was manufactured with excellent components.

All of their amps manufactured after 2001 carried a 3-year warranty. But when operated in "tri-mode", with normal speakers and a subwoofer, the subwoofer minimum impedance rating was 8 ohms. And the normal speakers should be operated through a high pass capacitor while the sub needed a 15.9 mH low pass filter inductor.

The MOSFET's and resistors can probably be replaced at a qualified electronics shop. If you are somewhat handy with a soldering iron and have a controlled temperature soldering station, you can do it yourself. Parts are available from: http://www.allelectronics.com/ and http://www.mouser.com/

Hope this helps.
