Frequently Asked Questions
General
Do you accept sample order?
Yes, we accept sample order to test the quality and service. Just let us know the radio/amp model number you are interested in or place sample order directly from our shop.
What is the MOQ?
No limit, but the bigger order quantity means better price.

What’s the IP rating for the waterproof radio/amp?
The IP rating is IP56, the radio/amp can withstand direct jets of water splashes or heavy rain, but it can not withstand complete submersion in water.
How to determine power needed for speakers?
The best method when matching speakers to amplifiers is to use the “RMS” power ratings instead of “Max/Peak” power ratings.
Why does my amplifier keep blowing fuses? Is it my power wire? How do I know if my power wire is "grounding out"?
If your amplifier’s main power wire has a fuse in-line that keeps “blowing”, it can be related to the wire itself or the amplifier.
You can tell if the problem is in the power wire by disconnecting the amplifier from the power wire, and insulating the amplifier end of the wiring from grounding against the body of the car (using electrical tape for this will work just fine). Then, simply put another fuse into the wire – if it blows, then somewhere along that run of power wire you have a cut in the insulation (or jacket) where the wire itself is touching the metal of the car.
If the fuse does not blow when the amplifier is not hooked up, then the amplifier is most likely the cause. In most cases, an amplifier will blow fuses due to internal damage caused by the way it was installed. Many times, an amplifier won’t show signs of improper installation until it’s too late, and blowing fuses indicates that damage has been done. An amplifier that blows the main power fuse immediately after you turn it on or when the fuse is inserted into the fuse holder is usually damaged in its power supply or output section, and will require serviced. Improper Gain and/or Bass control settings, low impedances, or blown/failing speakers are the most common causes of this trouble.
Why is my amplifier getting hot and shutting down?
There are several different reasons that an amplifier will get hot and shut down. Four of the most common are: Blown/grounded speaker(s),
poor power and/or ground connections, too low an impedance (load), or Gain/Punch Bass control settings too high.
What size of fuse is needed for the radio/amp?
As the fuse is different from model to model, please read the spec page carefully with fuse information.
What size wire would you recommend for +12 and negative wiring?
Normal 4 gauge wire will be fine. The connection should be well protected to avoid corrosion.
Does this radio/amp run on 24V?
No, it should be 12V DC, a marine battery with 12V output is strongly recommended.
