Bose 321 power woofer buzzes but produces no audio sound


I assume the other two speakers are working fine. Contact Bose and ask them. Could be a simple fuse. Sounds like a fried speaker driver, but do this first. Take the back off and check the power amplifier for a blown fuse. If none, disconnect the power amplifier. Reconnect the speaker cabinet w/o the built-in power amplifier to a known good amplifier to see if the speaker works. If it works then you know its the built-in power amp that's fried. Contact Bose for a replacement or better yet buy a another one with a higher RMS watt capacity. Wattage ratings in other than RMS are worthless. JBL and Cerwin Vega produce high wattage units. You need to keep the volume lower to avoid the problem in the future.

Set dead


Hi,you can use the following instructions below to troubleshoot the receiver set that is dead.

Instructions



Turn the receiver off and disconnect the power cable from the wall and the back of your receiver.

Test the cable with a multimeter to verify that it is working properly and supplying the receiver with full power. Multimeters are widely available through electronics supply shops, hardware stores and various online retailers. Different multimeters give different readings, so check your operations manual if you are unsure how to test a power cable for continuity. Replace the power cable with a working one of the same type if the original cable is not working properly.

Connect the multimeter to the pins where the power cable connects to the amplifier if the cable is working properly. This is the same area from which you disconnected the power cable in the first step. This is a particular process and all multimeters use different readings to test for pin-out continuity.

Check the fuses on the back of the amplifier if the multimeter shows a correct reading when you test the power cable and power connection on the back of your amplifier. Look carefully for a cracked filament within the glass tube; even a small crack can result in power failure or intermittent operation. A blown fuse will generally look gray or black around the edges or inside the glass tube. Blown fuses will not provide power to the amplifier and are a common cause of no power or a single dead channel, depending on the location and type of fuse.


Tips & Warnings

Opening the amplifier is not recommended, as there is a risk of electrical shock and you may void the manufacturer's warranty from Yamaha or any warranty provided by the retailer you purchased the amplifier from.

Always replace fuses with the same voltage fuse. Using the wrong type of fuse can damage your amplifier.

Do not try to open the receiver and fix the power supply if you believe that you have a power supply problem. This is generally quite dangerous if you do not know exactly what you are doing or are not working with the proper tools.

Hope it helped..

APX200.2 Marine Power amplifier. Problem: No audio, No power light on amp. 12V to amp is good, fuse not blown. Head unit works.


is the remote power good? also, make sure you have good ground(grind the connection clean if connected to chasis). If that don't work and the fuses on the amp are good, then the amp is blown.

Amplifier Powers on But Does Nothing!


Try finding a better ground some amps are more finicky about ground than others. Try running a wire from the ground on your battery to the ground on the amp if this works then you will know you need to find a better place to pick up a ground.

Trying to power a amp with 16 volts. possible?


Golf carts do not have a charging system. If you are going to use battery power only, why not just add (1) 12V car battery instead of (2) 8V??

MA Audio runs (ran) their bench tests @ 17V. All the power ratings advertized are at 17V.

The power supply for the hk4000D is unregulated. So the more voltage = more power.. 8V-16VDC.

  • RMS Power @ 14.4V
    • 1800W x 1 @ 4 Ohm
    • 3600W x 1 @ 2 Ohm
  • RMS Power @ 17.0V
    • 2000W @ 4 Ohm
    • 4000W @ 2 Ohm
    More input voltage means the amplifier will have to work less hard to make power.
    Don't expect the amplifier to work for very long however. the current drain on a class D amplifier is huge. There are no on-board fuses protecting the power supplies, so be sure to have at lease a 150A power line fuse.
    With 150A current draw - even with the amplifier at 1/2 gain - expect to get 10.6 minutes of listening time from your 16 volts before recharging - also note, the amplifier MUST see 8V to turn on, there is a built-in voltage sensor that will shut down the amplifier if voltage is too low.

    Amplifier does not work


    remove the speaker wires and re-test. If the amplifier powers on, without fault, you know the sub(s) and/or wiring are the culprit. If the power and ground are ok, take the amplifier in for service. The indicators are there to let you know of a problem. If it is an internal one, a certified tech will be required.

    Sound cuts when volume is turned up


    check that power amplifier rating(how many watt)must be more than total speaker rating by 20% at least..
    exampel:if speakers watts are 100 watt-amplifier watt must be 120 watt.

    Subwoofer


    Most AV receivers do not have a built in amplifier block to drive a subwoofer, and merely provide the subwoofer output channel at line voltage. Thus, a powered subwoofer is required. Does the subwoofer require mains power? From your description, I'm guessing it doesn't. If not, it does not have a buit in amplifier, you will need to purchase a monoblock amplifier, which is just a mono amplifier with a volume control, no tone controls or anything else. Make sure that the amplifier power rating is as close as possible to the subwoofer power rating, as it is quite possible to blow a speaker by using an amplifier whose power output is too low, by overdriving the amplifier , and putting DC through the voice coil when the amplifier clips. If it does require mains power, it will have an amplifier built in, but does not have line level inputs.

    Amplifier Not powering on.


    Amplifier power problems are generally pretty easy to troubleshoot as long as you have access to a digital multimeter. You need to check the DC volts on the power terminal and on the remote terminal. For the amplifier to turn on, each terminal needs to show around 12 volts. From the sound of it, I suspect a problem with your main power wire, but the multimeter will make certain. If you show voltage on both terminals (with the black probe on the ground terminal) and the amp still doesn't turn on, then there's a defect in the amplifier.
