If an amp has no load, as in there are no speakers connected to it, then it will go into protection mode because it sees an infinite load. Be thankful that it has a protection mode, or it would be toasted!

SOURCE: wat kind of wire should i use

What does the fuse on the back say? AWG 4 has around a 60 amp capacity, AWG 2 is about 95 amps. I wouldn't suspect you would need larger than 2. Remember the higher the Gauge the more Resistance per foot you have which means more of a voltage drop at higher current.

i believe your amp is 2ohm stable so be sure your speaker are wired for a 2ohm load or higher anything below 2ohm would throw the amp into protect

I have a TN250/1 MTX class D, mono-block amp, protection light comes on and thats it. Whats the problem?


Two things, a problem with the speakers, or the amp is toast. If there is a short is the speaker, wire touching, bad voice coil, the amp will go into protect. I have also seen many, many MTX amps that go bad, and just stay in protect. the easiest way to check, is to unhook the speaker wire from the amp, then power it up, if it still goes into protect without a speaker hooked to it, you have a bad amp. Hope this helps.

1 10 jl jl 250/1 mono block amp cuts off an on help


your subwoofer is wired incorrectly to your amplifier. Figure out which ohm load of subs you have and then what ohm load options your amp is stable at. Next go to either the Crutchfield website. find their learning center. go to subwoofer wiring diagrams. or go to www.the12volt.com and find their section on it

I have a JL Audio 12 ich subwoofer rated at 8 ohms. also a mono block insignea amplifier at one ohm stable 1-4 ohms. how to i wire it safley? possible?"


Your amp based on what you say would have no problems whatsoever with an 8 ohm load, not even if it actually has dual 4 ohm coils and you wire them in parallel giving a 2 ohm load (don't know your particular sub).

Every good car amp has protection circuits to prevent itself or the speakers from damage from too low loads so it shouldn't be a problem even if you screw up with your calculations. A good amp should even be capable of dealing with a dead short on a channel, zero ohms, activating protection of course.

Good luck and don't worry!

Trying to figure out what kind of amp i got amercian pro vs-3507?


The VS3507 Is a class D monoblock.
Your optimum wiring for this amplifier is a 2 Ohm load - so it produces its full potential power of 350W RMS.

To Achieve a 2 ohm load, the most common load is one of the following...
(1) Dual 4 Ohm Voicecoil Subwoofer Wired in Parallel.
(2) 4 Ohm Voicecoil Subwoofers wired in Parallel.
(1) Quad 2 Ohm Voicecoil Subwoofer wired in Parallel/Series.
(1) Single 2 Ohm voicecoil subwoofer.

The fuse from the amp to the battery keeps burning


maybe it cannot accomodate too much power running on it...too much current, try another fuse with higher ampere rates

Mmats d500.2


  • It is capable of driving a 2 ohm load.
  • It is a single channel amp, so bridging is not applicable. There are two speaker connections, true, but they are tied together internally.
  • It's rated at 500W @ 2 ohms
  • The issue you're going to have hooking up the subs you own is that you're not going to be able to optimize the output of the amp. If you hooked all of them up in parallel (both 15w0 as well as the dual voice coils of the 15w6), you'd be putting a 1.7 ohm load on the amp, which it may not like. In my mind, your best bet is to either put both 15w0's in parallel (125W per sub) and not use the 15w6.....OR.......use only the 15w6 with the dual voice coils in parallel (350W to the sub).

Amp staying in protection mode


No, this amp is not a heavy power consumer- matter of fact it takes very little power to run.Maybe you should check the fuses on the amp to see if they are what is recommended.Also check your fuse kit to your amp- your fuse might not be big enough.If neither works take it back where u got it.
