I have an amp hooked up in my car.when I tried to connect the two woofers up to amp, the stereo cut off and the deck said protect.now that's all it will do is read protect.Wat do I do?


This is a circuit protection to stop you frying your audio! Could be a short circuit or wired wrong......remove the fault and it should reset! First remove the 2 sub woofers since that was when this happened and test the deck!

It goes into protection mode. how do i get out of it?


Check your speaker connections and speaker resistance of each speaker with an OHM METER. Most speakers are marked either with a 4 ohm or 8 ohm impedance. You might have a burned voice coil (shorted out) and the amp senses the short and goes into protection mode to protect the amp from being overloaded and burning itself out.

Need a wiring diagram for a american pro 1406


Very simple :

12V+ = Red 8 Gauge Wire to positive battery terminal with a 30 Amp fuse

Ground = Black 8 Gauge wire to non painted surface on chassis of car.

Remote Turn on = Blue / white thin wire from radio's blue/white , this will turn on your amp.

A set of RCA cables which are self explanatory. Out to In or In to Out
Radio to Amp under carpet to back of vehicle along with your blue wire.

Then you have your speaker wires, you hook these up to your subwoofers.

Hope this helps, good luck.

Just installed the sub it work for 10 sec then quit checked the amp and its working with a old sub do the subs freeze or something


The amp needs to "see" a load and if the new sub is incorrect the the amp will sense improper amps and will shut down, a protective circuit. Load the amp with the correct speaker....

Dont have wire schematic to hook up american pro bass machine limited edition model 1406,need to know how?


You should go to www.the12volt.com they are very helpful and pretty much have a schematic for every single car audio situation and they give you all your options. If they have nothing go to crutchfield.com and go to the learning section then subwoofer and amp wiring. It all depends on the subs that u wanna hook up to it as well as the ohm impedence and the amount of voice coils and so forth they have all of that.

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.

Sounds like the thermal protection on your amp is doing its job. You can put an external fan in to help in cooling, like the crossflow type shown here, or a couple of muffin fans like these (look familiar?). You may have fashion a bracket to mount the fan(s), but that shouldn't be too much of a problem. Many fans are shipped with mounting tabs attached.

OVERHEAT PROTECTION


The thermal protection would have reset when the amp cooled down. When cool, if it still goes into protection when it powers up, there are likely blown output transistors. To be sure it's not a wiring problem, disconnect the speaker wires 'from the terminal block of the amp' and disconnect the RCA cables from it. If it still goes into protection, the output transistors are almost certainly shorted.
