I changed speaker with a larger magnet speaker, now amp is dead. Was it the speaker change or something else

Speaker needs same ratings or it might damage unit or speaker . 4 ohm 8 ohm or 16 ohm and wattage ratings need to be within ratings for both , polarity also should be checked

I have a spider Jam and have added a subwoofer to the speaker connection with no problems. The only thing I can think of is if the two wires got connected or touched for any length of time the amp might have shorted out due to the "short" in the speaker wires. In my history of working with guitar amps, ( since 1979) changing a speaker should NOT cause the amp to not work. Look for a fuse .

Mine did the same thing. Not sure if it's a good/bad thing but the amp is good. Hope this helps

Thanks, that might have been the reason for I went from some mid range infinitys to 4 Martin Logan towers and the problem seems to have disappeared, I'll keep pushing the volume up after the recommended break-in period of the ML10'S.Looks as if the problem was in my old speakers, I was able to floor the receiver with the ML10s without triggering the protection circuit so now I'm going to sit back and enjoy warping across the various universes with Startrek and the Skywalker clan.

You will have to cut the connector off and hardwire it to your speaker. Use waterproof splice connectors. Also make sure you get a wire diagram or write down whicheck color your old connection hooked up was positive or negative

Check all powers and grounds connection then double check and make sure your speakers are wired to the right resistance

Have your amp checked by a factory installer. Planet Audio is very good at making it right with there customers. I'm sorry but I have never had one do that. So it my be internal.

Well, this is hard to say. But here's my experience. About a year ago I was moving my amp with headphones plugged in. I stepped on the headphone cord and it pulled the jack loose. Neither 'phones nor the speaker worked. I took the amp apart: the jack had pulled off a printed circuit board but otherwise was not damaged. I eventually was able to solder it back on. It took a number of tries, for a while I was only getting the left channel through the 'phones and I had to keep taking things apart and redoing. Finally got everything soldered right. However, now something is a bit loose and the speaker isn't working. If I jiggle the jack I sometimes can get it back. Sometime I'll have to open it up again and resolder things, but right now I am just using it for practice with the 'phones. I suspose if I took it to a pro, maybe I could get it done up totally right. However, I am too cheap and sometimes I have found that sometimes pros refuse to work on a something because they either don't deal with the brand, or perhaps in this case, decide the way to go is replace the whole circuit board.

In the past I have had to deal with mismatched speakers of high wattage. I used a matching impedance amplifier.. Unacceptable here, So a possible solution could be, hook it up as normal. If it works to your satisfaction all is well. If not go to Radio Shack and buy a 4 ohm-1 watt resistor and connect it in series. Depending on speaker design, that could bring out the power to an acceptable level. If that fails... well ... its filter stuff and the cost is probably unacceptable.

I believe there is a switch in the back for stereo, or bridged. Set it to stereo. Also how are your speakers connected to the amp? Are you using the speakom. Connectors? Check your wiring

My apologies for the long time to respond to this, this is the first time I get asked a question through Amazon. Anyways the power supply worked great for me but the problem could be from the power source or the speakers. So try to test your speaker with the same power supply at another location in your house or a friends house maybe with a portable mp3 player. Also if someone else has the same speakers borrow the power adapter or swap your friend's speakers from the monitor just to test it.

Is the battery dead? I had one of these amps suddenly stop working for me after about a year of use, I think the wiring goes goes out eventually. You may want to try returning it.

Anyone try running the output through the Fx Loop Send, increasing gain and lowering the Volume(so the speaker isn't heard)?But if this works you'll loose the Power tube phase. I'm using Blackstar Ht Metal's Emulated Output for this purpose.

Search for the woofer for the PMO.4n and see if it makes sense to replace just that speaker. Taking another route, depending on what is actually wrong with the speaker driver, it maybe fixable. For instance, if the outer foam is split but not the cone you can likely purchase a repair kit for under $20 to fix yourself. I have done this before (not on this speaker however) and had perfect success. Lastly, its Christmas time and you can suggest a replacement speaker system as a nice gift from someone to you.

To the person who said their amp is shutting off........please check your voltage regulator. I dealt with 2 pioneers and 1 JBL amp which did the same thing. The amps were good, but turned out to be my voltage regulator. Car stereo always worked fine, but amp would go into default.

I currently am having trouble with the amplifier as well. I don't know where you would get replacements. I would (and will) be calling the company.

I would not recommend replacing the speaker as this amp sounds great out of the box. One of my jamming buddies had me order him one from Amazon as well. He plays an Emmons steel guitar through it!

How did you loose? Did you look hard for them? I know it's silly to ask... But otherwise I see you having to get a new set.. I know uou have the larger one but I haven't tried putting it in.. I'm sure it will work just as good if not a lot louder.. but don't know if it would be comfortable or how safe.. remember the larger the magnet the more it will react to magnetic fields in it's reach.. I know u could hear the magnetic fields from devices and motors with the lil ones.. soo I could imagine that would be amplified.. you can look around and see if you can order replacement magnets, but the wait might be as long as the device itself..
