Check the connections to the amplifier. Make sure that the insulation

for all wires has been stripped back far enough to allow a

good contact area inside the terminal block.

Check the input connectors to ensure that they all are making good

contact with the input jacks on the amplifier.

My amp turns on good but after a while of too much bass causes a ugly sound too loud what could it be? Can it be repaired?


If you have over driven the amp by playing it real loud with the bass control turned up, it is very possible that you have toasted the output stages of amp.
Every time you boost a tone control by 3 db you have doubled the output power at that frequency. So if you are "coasting" along at a nominal 75 watts, the moment you boost the bass by 3 db the amp has to put out 150 watts at that low frequency.. Go to +6db and now the poor amp has to kick out 300 watts! And so on.

Rule of thumb - you never use your tone controls at very loud levels. Tone controls are there to compensate for the poor frequency response of the human ear at low volume levels - the Fletcher Munsen effect. At low volumes our hearing with the lows and high frequencies so when you play something at low volume you boost up the bass and treble to compensate for poor hearing. At loud volumes our ears respond properly.

Why does my green power light blink and my amp not work


There are three status indicator lights on the top of the amplifier. These are as follows:
1) "Power" (Green): lights to indicate that the amplifier is turned on and operating normally.
2) "Thermal" (Red): lights to indicate that the amplifier has exceeded its safe operating temperature, putting the amplifier into a self-protection mode, which reduces the power output of the amplifier. The red light will shut off and the amplifier will return to normal, full-power operating mode if the heat sink temperature drops back to a safe level.
3) "Low ω" (Amber): lights to indicate that the impedance of the speaker load connected to the amplifier is lower than the optimum impedance load range for the amplifier. When this light is on, a protection circuit engages and reduces the power output of the amplifier. The amber indicator will also light when a short-circuit is detected in the speaker wiring (this can be a short between the positive and negative speaker wires or between either speaker wire and the vehicle chassis).


There is only one condition that will shut down an undamaged 500/1v2 completely... If battery voltage drops below 10 volts, the entire amplifier will shut itself off. The green "Power" indicator on the top of the amplifier will turn off when this occurs. The amplifier will turn back on when voltage climbs back above 10 volts. This may happen in a rapid cycle when bass-heavy program material causes a weak charging system to dip below 10 volts momentarily. If this is happening in your system, have your charging system inspected to make sure it is working properly.

If your amplifier is blinking Green, and no output is coming out of the speaker, you may have internal damage to your 500/1 Amp.

"My amplifier turns on, but there is no output"
  • Check the input signal using an AC voltmeter to measure the voltage from the source unit while an appropriate test tone is played through the source unit (disconnect the input cables from the amplifier prior to this test). The frequency used should be in the range that is to be amplified by the amplifier (example: 50 Hz for a sub bass application or 1 kHz for a full range / high-pass application). A steady, sufficient voltage (between 200mV and 8.0-volts) should be present at the output of the signal cables.
  • Check the output of the amplifier. Using the procedure explained in the previous check item (after plugging the input cables back into the amplifier) test for output at the speaker outputs of the amplifier. Unless you enjoy test tones at high levels, it is a good idea to remove the speaker wires from the amplifier while doing this. Turn the volume up approximately half way. 5V or more should be measured at the speaker outputs. This output level can vary greatly between amplifiers but it should not be in the millivolt range with the source unit at half volume. If you are reading sufficient voltage, check your speaker connections as explained below.
  • Check to ensure that the speaker wires are making a good connection with the metal inside the terminal block. The speaker wire connectors are designed to accept up to 8 AWG wire. Make sure to strip the wire to allow for a sufficient connection with the metal inside the terminal block.

Hi, I have lost the base in one of my bose 802 speakers, Tried all the obvious stuff, amp, eq, cables, etc with same results, can anybody help?


If you have switched speakers to confirm that that speaker is faulty and not your amp, it's a question of opening up the speaker and looking for obvious damage. If none then find the bass driver and remove one connection to it. Then with a 1.5 volt battery connect the + to the plus of the bass driver and the - to the other terminal. ONLY FOR A SPLIT SECONED! If the bass unit works it should pop and you should see the cone move. If it doesn't either the wire from the speaker has come away from the terminal point (bad soldering) or the coil is open circuit (new bass unit I'm afraid). If it does pop it's something on the crossover that's faulty. Check for bad soldering first.

Amplifiers GT Series GT5-A604 ........explain settings


the amp probably has a x-over knob, a bass boost knob, and an eq knob. the eq is probably an internal crossover switch that will take the output from either high range (tweeters) or full range (6x9s) or low pass (subs) leave it on low pass. the bass boost however, will add distortion if turned up too high. its not noticable in the car, actually it sounds louder in the car but if you open the trunk and listen, you can tell its distorted bass and actually frying your speakers. the x-over knob is used to tune the frequency at which the amp stops pushing out bass tones. if you like rock music loud, turn it up higher, if you like low deep rap bass, turn it lower. keeping it too high might give you bad sound from either type though. ALSO THE GAIN OR LEVEL.IT IS NOT TO MAKE YOUR SUBS LOUDER IT WILL BLOW THEM .the gain is used to set your amp to your head unit which there is a procedure to do it.

Bass goes off when i turn up the volume


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.

Green light turns red on hard notes with kicker 750 mono amp


First off, never, ever replace a blown fuse with a bigger one (especially one that is almost twice as big) unless it's an absolute emergency. Most of the time, the reason a fuse blows is because of a problem with the device (in this case, the amp). By installing a larger fuse, there's a very good chance the problem will become permanent (i.e. busted amp).

The amp could be going into an overcurrent mode when the bass hits and power cycling itself to try and reset the problem. If this is the case, take it to a local electronics repair shop and see what they can do.

It's also possible the input voltage to the amp is dropping too low during the bass hit, making the amp restart. Try putting a 1.0F or higher capacitor on the battery to buffer the power during the bass hits.

Amp Issues


1800W peak output at 2 ohms
975W peak output at 4 ohms
600W RMS (continuous) at 2 ohms

It is going into protect mode for a reason.
Disconnect the subs and turn everything on again. If the light comes on, the problem is internal and will need servicing by a technician.
