Question about Polk Audio POLK PA1200.1 1200 watt monoblock amplifier

Open Question

Need circuit diagram for a PA1200.1 class D monoblock car audio amp

Amp is getting power from battery and blue accent lights turn on, but no power to the subs. Tried direct connecting an mp3 player to amp to eliminate RCA cables and still no sound. Amp was wired at 1ohm for 3 months and working ok. Got warm one evening and went into protection mode and hasnt worked since. Amp only got pushed hard for ten to fifteen minutes at a time, but only about once a week for those few months.

SOURCE: SUBS

the bigger the wire the better the resistance but even a wire wont do much
the only thick i have on my sterio is the battery wire the rest is cut old extension cord wires and mine sound fine never cut out on me and i have 1600 watts going threw amp

more power putting threw the hotter the amp hotter the amp more the cut off amp

quite possible you have too much power going to speakers if your bridged it will blow out amp found that out from bridgeing but thank god i had it fused

turn down your gain and bass boost and work up to good sound say your sterio is 1-60 volume your should hit right around 30 volume by turning gain and boost untill quality sound this is your safe zone gain should be set 1/2 volume of sterio to 3/4 pushing it nothing more or total melt down

Is this NEW? Or did it just fail spontaneously after working for awhile?

Is this just a remote control issue or is the sub dead, too?

From the manual...

No sound coming from subwoofer.

If hookup is "SUB OUT" to LFE, check and make sure your receiver is set to Subwoofer=YES. If hookup is via speaker wire, check that the polarity of the wires is correct.

Subwoofer has no power.

Is the AC MAIN switch on? Check outlet; check fuse after unplugging the subwoofer. The fuse is located under the power cord
receptacle. Fuse type and rating is found on the back panel.

Remote control doesn't work.

Remove the plastic tab to activate the remote control's battery or try replacing the battery. Ensure the IR sensor is not blocked.

If it's a new problem with a previously working remote...

It describes a way to possibly fix your remote or at least prove it works or doesn't.

or eBay: search for "(model) remotes", check the 'include description' box. Usually cheaper than the vendors.

SOURCE: 5channel amp 6 speakers how

if it is a 5.1 channel amp wire the center speakers together into the same port. wire the two front speakers in the or der that they would appear on the amp (such as left front speaker to the left front speaker terminal on the amp etc.) and do the same for the rear speakers. and all you should have left is the sub-woofer channel in which you do not have to worry about.

SOURCE: I have a Polk Audio

The protect light appears when one of the outputs on the Polk is shorted - the cause of this can be internal or external.
To find out which just disconnect all the speakers from the Polk and start it - if the warning is gone then it's external, one of the speakers (or its wires) is shorted, connect them one at a time until the warning returns and you will know which one. If the warning is still there then it's internal, one of the amplifiers inside the Polk has failed and it will have to be taken out of the car, dismantled and tested by a pro to find out what happened .

Got a service manual / circuit diagram for an OV2-800? I have one keeps blowing input fuse when remote wire is energized.


Hi, are you using the blue wire from the head unit to turn on the amp? The turn on voltage is more like 5 volts--not battery voltage, so you have to use the blue wire to turn on many amps.

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.
