Remote wire hook up

My punch amp is hooked up to the battery & is grounded.It does not power up so my question is does the remote wire go from the amp to the battery (Which does not have any juice when checked with a tester) or what. Thanks.

Re: remote wire hook up

The Remote wire should connect to the remote turn on lead from you radio(most aftermarket radios use a blue and white or a blue wire for the remote turn on). This wire will send a 12v signal to the amp from the radio when the radio is turned on. You can disconnect the remote turn on lead from the amp and jump a wire from the terminal marked battery to the remote turn on terminal just to see if the amp powers up. Do not leave it this way however because your amp will not shut off and your battery will go dead.

I just bought a punch 500 a2 amp. i hook up my ground, then try to hook up the power cable and it sparks. my punch 250 was hooked up minutes prior to this so i know my wiring is good. what the heck is the...

The spark could be from the capacitors in the amplifier charging. Make sure the main fuse from your battery is still good and also check all the fuses on the amplifier. Verify all the wiring is correct and make sure none of the wires from inside the positive cable are poking out and touching the vehicle or amplifier chassis. If you have a 1k ohm resistor, you can put it in series with the amplifier power line to slowly charge the capacitors. You can do that by following the directions from the link below. After doing all that, remove the 1k resistor, hook it all up and try it again. If it still doesn't work, make sure your remote wire coming from the head unit has a voltage on it when the head unit is on. You can get a cheap volt meter from a hardware store or wal-mart.

Bad ground sounds like you may have paint or undercoating stopping the ground from making good contact or unhook the remote wire and run a small wire from the main power to the remote hook up and see if it works ...... May have a faulty remote

Amp shut off has power and grond and remot but only my p550 shut off fuses are ok and all other amps are wourking

how many subs are you running on this amp, and how many ohms are they. if the are bridged, try hooking up stereo and see if the problem still occurs. make sure your scrape off all the paint where the amp is grounded to the frame which should be less than a few feet. i'd also recommend running at least a 4ga wire for both your power and ground.

My amps protection circuit keeps cutting on and off when i hook up my amp

Hello m_george191,

Usually an amp will go into protection when there is a problem with the wiring, impedance load, or when overheated. Immediately when hooked up, it probably isn't overheating.

Most likely, there's a short or ground on a speaker wire, an input, or a faulty ground to the amp itself. Frayed or broken insulation, stray wires shorting across the terminal blocks, and shorted voice coils can all cause the protection circuit to activate.

First check your power and ground wires. Then disconnect the speakers and inputs and see if the amp powers up normally. If the amp still goes into protection with all wires other than 12V +, Ground, and Remote disconnected, the amp itself is defective. If it powers up normally with all other wires disconnected, reconnect the inputs one at a time to determine if one of them causing the problem. Likewise, reconnect the speaker wires one at a time.

Hope this helps.

Hooked my punch Punch P450.4 up to speakers and ran rca cables to front and it wont work

Hi Jon,  you need to hook the Remote wire up to the Radios  Blue remote wire.  The car battery power stays on all the time.  The blue Remote wire watches to see when the radio turns on, and signal the amp to turn on as well.

Make sure the amplifier is turning on. Remember ther is three wires that power the amp Battery constant, Ground which in a fiberglass boat run ground to battery not motor, Plus make sure the remote wire is hooked to power, generally it is switched power. But if the amp is not turning on temporarily hook remote and power together to battery and see if the amplifier turs on. Second be sure you have a good set of RCA cables hooking the radio to the amp. And finally check and make sure the gain is turned up on the amplifier.
