AMP HAS POWER NO BASS IN BOX RED LIGHT BLINKING SHOWING 3.03 OR E.03

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

Blinking codes details to many popular brand electronics devices are given. If blinks continue without any pause, the main board is faulty. Search the sites by type in the brand name of your set, in its search box at the right column. View it on a desktop or in web View by mobile. Mobile view has no search box.

Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy. There are more than 1200 posts to different brand TVs now. Pull up older posts there. Blinking codes to so many brand TVs are described in detail here.

does your bass have active pick ups?
do the ratings on your amp match the ratings on your speaker?
are you using a pedal?
does your pedal have an output adjustment?
have the ground on your bass checked.
make sure you're using the right kind of cable.
and be sure that the outlet you're using is grounded.

ITS IN PROTECT MODE. EITHER ITS BLOWN OR THE SUB IS TRYING TO PULL TOO MUCH POWER. UNHOOK THE SUB AND SEE WHAT HAPPENS IF THE LIGHTS STILL BLINK THEN AMP IS BLOWN. IF THEY STOP BLINKING AND ONLY ONE STAYS ON THEN LOWER THE SETTINGS ON THE AMP AND TURN THE BASS AND VOLUME DOWN ON THE DECK TO LOWER THE AMOUNT OF POWER BEING PULLED FROM THE AMP.

the red light is for power in protect mode it should be orange and it will not emmit sound if you think you should have better sounding bass or more bass you can try to play with the gains on the amp or possibly if you have the negative or positive hooked up wrong from a speaker to the amp this will cause the bass to be lower and somewhat distorted double check your positive and negative wires from the speaker to the amp and make sure they are correct

You need to install a heavier gauge wire to your amp and a capacitor. It works fine at low volumes because there is enough wattage from the battery to power the bass output of the amp but at higher volumes the amp does not have enough power.

Heavier gauge wire supplies more poer, and a capacitor stores a reserve of wattage for the amp to use so that it does not run out while blasting your tunes.

the amp is going into protect mode due to something wrong in the amp or some thing in the wiring to it ooh yea if you are getting 18v power to the amp that is way to high it should not be higher then 15v if the amp is in protect mode it will not play at all.

It probably has shorted output transistors. To eliminate other possible causes, read through the following page.

Amplifier in Protect Mode - Troubleshooting

Let me know if you have any other questions.

Hi, best practice when troubleshooting a no-sound Bose Lifesytle system is to first begin with the internal sources (i.e. the AM/FM). Bose Lifestyle system when connected properly (media center and bass box via the data cable) should show a steady green light underneath the bass module. Begin by simply playing AM/FM tuner and try to increase the volume till 45 (normally the sound becomes audible at this level). If the system still has no sound, then try to check if the bass module is steady green. When you see a blinking green LED (slow green) then do kindly check the DIP siwtch (red latch switch with white mini switches) just beside the Light and data connection. All of the switches should be in "ON" position (basically toggled upwards with the arrow marking indication). Before changing DIP switch settings do ensure that the bass module is not connected to the electrical power. after ensuring that all DIP switch are in the "ON" position, connect the data cable firs and then power up the bass module. Then you should see the bass module blink green twice and once you turn on the nedia center, the green blinking should turn steady green. That should sort out your problem.

Also do note tha this procedure applies only to Series II Lifesytle System and does not include the Series IV (with the smaller bass module).

If all still fails, there is an internal problem with the bass module which would require servicing.

Hope this helps!

Check the main amp fuse under the hood, even if it looks good just change it. Often times that light on the amp can come on just from the power amp tunon wire. Try a friends subwoofer box just to make sure the connectors on your box are good, and if that doesn't work then give me some more details....year/make/model of car, what kind of sub, what types of things do you see on the side of the amp....is there a green light as well as a red light?
