pls. try switching the speakers, if the sound switch from left to right or right to left , one of your speakers has an open circuit. check the wire for any open link or check the speaker for an open voice coil.

I need to wire 3 woofers but 2 are dual voice coil and one is single voice coil


sure, if you wish to wire them all together, wire the first dual voice coil subs first voice coil negative to 2nd voice coil positive, second voice coil negative to single voice coil sub positive, and single voice coil negative to 2nd dual voice coil subs 1st voice coil positve (again with the second dual voice coil sub, run the first voice coil negative to the 2nd voice coil positve) your speaker leads will be attatched to first dual voice coils 1st voice coil positive, and 2nd dual voice coils 2nd voice coil negative)

Protect mode


The most common cause of this is that one of the speaker voice coils is shorted or the wiring to one of the speakers is shorted. Disconnect the speakers one at a time and see if the amp goes out of protect, if no change you have a shorted output circuit in the main amp section.

My speaker isn't working properly.


Hello sir, hi there, usually speakers are replaceable if its not working, if the value of your speakers are quite high, you may need to rewind the voice coil, or find a replacement voice coil for it, much better you need to replace the entire unit. Here are some test to confirm if your speakers are busted. 1. get a double A battery. 2. connect the negative terminal to the negative of the battery using a black wire. 3. connect the positive terminal of the speaker to the positive of the battery intermittently with a red wire. 4. you should hear clicks. no clicks it's busted. replace the driver.
test for voice coil free flow. press gently the cone, and feel the free movement, if you feel friction or scratches, replace the driver.

On/standby Red light blinking can't turn on system


It's in protection. Disconnect all your speaker wires at the receiver then power it up. If it stays on, the receiver is ok and you need to check all wires and speakers for shorts. The easiest way is to reconnect one speaker at a time and test power until it shuts down, then disconnect the speaker wire at the speaker and test again. If it stays on, meter the speaker for shorts or bad voice coil. if it still shuts off, check your wire or replace. If the receiver's power still flashes with all speakers disconnected, it needs service or replaced. Before reconnecting your receiver after repair or replacement, check all wires and speakers 90% of the time, that's the cause. Hope this helps. If you still need help, post a comment and I can help you troubleshoot further.

I have cambridge soundwork tower speakers and if I turn the volume up , the receiver shuts down to standby mode. Can i dissable this


It's a safety feature of your receiver. It will go into standby when you turn it up if there is speaker wires touching or a short somewhere in the speaker wire. Or could be a short in one of the drivers (tweeters, mids, bass drivers) voice coils. Firstly check to make sure there are no strands of speaker wire touching each other between positive and negative on speakers and receiver hookups, this is usually the problem

How do I wire 2 dual voice coil woofers to monobloc amp at 1 ohm.


the higher the impedance, the better sound quality the amp has. It's the lower ohm you have to worry about. Zero ohms is a dead short. 1 ohm isn't too far from it. 4 ohm is farther yet. The lower the ohm, the harder the amp has to work. parallel,all speakers positive terminals to the positive terminal of the amplifier and connecting all of the speaker negative terminals to the negative terminal of the amplifier. in this case Parallel wiring is connecting components to a source so that they share the same voltage

Most often it is due to improper speaker loading. In other words, it needs to have from 4 to 8 ohms speaker load and you wired your speakers in parallel when they should have been wired in series. What would have been an 8 ohm speaker load in series, turns into a 2 ohm load when in parallel. And with dual voice coil speakers you just compound the problem. And don't even get me started on bridged outputs.
Anyway that is what usually causes an amp to fry. Good luck.

Sound problem


Make sure all speakers that are hooked up sound ok. If any of them sound lower then the others or sound distorted you may have a speaker with a partially shorted voice coil. If speaker or speakers pop when power is first applied you may have a grounded speaker that should not be grounded. Each speaker wire rides on 6vdc and if any speaker sees a ground you will have 6v across voice coil which would explain any popping noise when first turned on and radio may play for awhile then overheat. be sure speakers are 4 ohm min per ch otherwise amp will run to hot. Just a few Guesses
