Question about Volfenhag ZX-7160 Car Audio Amplifier

1 Answer

Power problems My amp will turn on when the car does, but then turns off again right after. I checked the fuse and all the wires and the only one I found a problem with was the remote wire. Should I replace the wire itself or is there something else that could be wrong?

Re: Power problems

What you need to check is weather or not the head unit is not at do this,remove the remote wire from your amp.then put a link wire from the main battery wire terminal on your amp accross onto the remote terminal so you are basicly joining the main power terminal and the remote together.if it then stays on,you have a fault with the head unit itsself.allso check that you are useing the remote output on your amp and not the electric areil wire.if you find it is the head unit at fault,its not a problem becouse all you have to do is find a switched power supply in the car and use that as your remote on/off switching,but ensure you put in a inline fuse near to the source of power rated at 10amps. I hope this solves your problem.

I own a Orion CO5001 Car amp along with 2 2ohm speakers

There's a problem with the wiring. you popped the fuse/breaker in the amp. Replace the fuse or reset the breaker whichever the amp uses and then check your wiring. then try the amp again.

Just take your time with it. I've made my share of stupid wiring mistakes and have lost an amp or two because of it. So be careful! If you can't find the problem, ask a buddy to look it over for you. He might spot it. Other than that I'd say the amp is bad.

No sound from my car amp, wired up right won't come on

installed my Audiobahn A2300HCX amp to my kenwood head unit. Just got this amp off ebay, ran all my wires for my amp. Finally it was time to hear it BUMP, but nothing... As i calmed down form woundering bout if i got ripped off on ebay, i recheck all my wires, reground the wire to an other spot, check my fuse on amp, and inline fuse from power wire off battery, AGAIN NOTHING.......... FINALLY had an idea bout jumping a wire from the power terminal (off the amp) to the remote terminal (off the amp), AND BOOOOM my amp kicked on... TURNS out it was my remote wire off the head unit off the harness was bad never hooked up an amp to it before. BUT dont leave it that way the amp will stay on all the time i only did it to see if it works. THANK GOD IT WASNT THE AMP

I have a nitro 1200 watt amp earlier today it was workin with no problems we parked then came back in the car 3 hours later and it wasnt workin wont come on or anything just red light which is protecting...

Check your speaker wires, make sure everythings connected right with no short circuits, and check all of the fuses in the amp, and make sure none of them are blown. If all this checks out just check the battery wire, grnd, and remote wires. It has to be a wiring issue unless you busted your amp, but if was working when you tuned it off it should be alright... hop this helps...

Why doesnt my 2400 watt amp turn on?

The size of the wire affects the performance of an amp, but the amp should still turn on. 12 volts is 12 volts. So you tested with another amp, on the same wires, and it works fine.The only thing you can really check on the new amp is the fuses in the side. If those are blown, then you should be able to (Unless the amp is fried, and that's why it blew the fuses in the first place) fire it right up. If the fuses arent blown, and you have all your power, and ground, and still nothing.. Well then in that case the amp is just bad, and regardless of the wattage, you just don't fix a Pyle amp.

Memphis PR300.2 Amp protect light on

If it is not turning on your problem is it is not getting power. Check your fuses. The reason an amp goes into protect mode is usually because the subs are not wired up right. Make sure your fuses are good, you have a good ground, and make sure your amp turn on wire didn't come loose when you were putting the deck back in. As for the amp going into protect you probably wired the subs down to too few ohms and the amp you have can't handle it. Try hooking the subs up straight w/o bridgeing them and turn it up to see if it works. If you don't have problems with it then you wired your subs wrong.

Amp problems

The main thing that comes to mind is whether you've checked the in-line fuse on the positive wire. Most amp installations are supposed to have a fuse within 1ft of the battery terminal for just such a reason. Next, if you have a voltmeter of some kind (or know someone who does), check to see if you still have 11VDC-14VDC at the power terminals of the amp. If you do, then check the remote turn-on lead (which is supposed to connect to either your head unit or the ignition). If my memory serves, the remote wire should be high (about 12V) when the amp is being told to turn on and low (less than 2V) when it's being told to turn off.
