It sounds like your saying that you have two identical amp, that both are on the same power wires and remote wires and sam grounds? Well if thats the case then you did ok as One amp sounds like its blown. First tghing is check the main fuse. If its good and the unit still dosent resond then the power supply in the amp is blown as theres a switching supply that increases the 12 volts to get power to drive the Mosfet output devices. Was it ever working?? yes then the amp needs service. Do you know how to work on solid state elctronics down to componet level?? No?? Ok contact these folks at the addy im posting for you or take the amp to your local servicer. Good Luck. AudioSupport@VisonikCarAudio.com

I have Boss ar2400 4 channel amplifire.. I had connect two 15" kicker subs in bridge circuit. When i run the system it gets overheat in half an hour and goes into the protection mode. How can i solve this...


Problem is one of four things:
  • Impedance (ohm resistance) of the speakers you are using is below the amplifier's rating for operating in bridge mode;
  • You are driving the speakers at a volume exceeding the maximum power output of the amplifier;
  • The gauge of the wires you are using to connect the amplifier to the speakers is too small;
  • The gauge of the power supply wires is too small, and/or you are not using a large enough reserve capacitor at the power input
Possible solutions:
  1. If your Kicker subs are rated at 4 Ohms, and you are using them in monoblock configuration with the speakers wired in parallel (all + terminals to the + bridge output and all - terminals to the - bridge output), try either configuring your bridge circuit in a paired bridge, where a pair of amplifier outputs are bridged, each bridged pair driving a single speaker; or if your Kicker subs are rated at 2 Ohms, use a monoblock bridge driving the speakers in series (+ bridge output to + of one speaker, - of that speaker connected to the + of the other speaker, and = of that speaker connected to - of the bridge output);
  2. Turn the amplifier output down (but this is likely NOT the issue)
  3. Use speaker wire that is no smaller than 8 gauge for your application. 4 or 2 gauge wire would be slightly better but not worth the additional expense;
  4. Your power supply wire should be equal in size or larger than your speaker connector wire. Use no smaller than 8 gauge for your application. Also, use a capacitor no smaller than 2 Farads wired across the power supply input to the amplifier to compensate for pulse surges and car power dips. For your application a large capacitor will work better than an auxiliary battery or gel cell.

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.

How can i upgrade my av 302 to becomes best as konzert av-502


Hi,
upgrade your 302 to 502 need to replaced the toroid transformer, set of output amplifier, set of electrolytic capacitor.
Purchasing of these parts one-by-one is much expensive rather that you buy a brad new Konzert AV-502. Also upgrading the unit is quite tech and need a lot of experienced in electronics.
Hope that it may help you.
Have a nice day.

Will not put out sond


Hello billyelder,

If the amp is powering up but not producting any sound, there are 4 possible causes.

1) Incorrect or faulty wiring.
2) No input or input too low for the amp.
3) Defective speakers.
4) Incorrect amp or head unit settings.

Start by checking all of the wiring and onboard fuses. Especially check the speaker wiring and make sure there are no shorts or grounds and that the insulation is not nicked or frayed. Check the RCA cables by substituting a known good pair. Check the receiver (head unit) to see if there are any settings that need to be turned on for the preamp outputs to work.

Test the speakers on another output to determine that they are functional.

Check the amp settings and insure that filters, crossovers and gain controls are properly set. If your wiring and the settings all check out and the speakers work on another output, the amp itself is probably defective.

Hope this helps.

What to do


Hello dodgeram1980,

If you are not getting sound from any of the 4 channels, I'd suspect that either the amp is not getting an input signal or the amp itself is faulty.

Here's the "no sound" troubleshooting step-by-step procedure from the JL manual:

1) 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 5.O-volts) should be present at the output of the signal cables.

2) 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 Connector Plugs 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.

3) Check to ensure that the speaker wires are making a good
connection with the metal inside the Speaker Connector Plugs. The speaker wire connectors are designed to accept up to 12 AWG wire. Make sure to strip the wire to allow for a sufficient connection with the metal inside each terminal.

Hope this helps.

Assuming that you've confirmed that the speaker is in good working order and that the wiring isn't shorted in any way...

There are separate power supplies for the high and low amplifiers. It's possible that the one for the sub output has failed. If that's the case, the output transistors probably failed and that's what damaged the supply.

Generally, I'm willing to help people repair their amps but this is a large, complex amplifier and it should be repaired by a qualified technician.

The 2 + and 2 - connections are the same, just split into two. This is usually because, for high power amps, it's easier to route two 4 AWG wires than it is one 2 or 0 AWG wire. Both "+" will go to your battery (through a fuse block, of course) and both "-" will go to a grounding point.

It sounds like you have a broken output filter inductor in the amplifier. You should be aware that the speaker outputs of the amp are biased at ~40v DC and can give a good shock if you touch the speaker wire while you're grounded (touching the body of the vehicle).

 

When you connected the speaker as you did, I would have expected the speaker to move in or out and remain there while the wire was connected to the housing of the amp. I'll assume that the amp was screwed down to the chassis of the vehicle. If it wasn't, you may have more than one problem.

Jensen LXA400


I have this same amplifier. I have noticed several ways it will "not work" during my ownership of it. I have it connected to a seperate battery to save my alternator, battery, etc as it is a power hungry beast for how low the output wattage is. Test the input voltage to see if you have enough, one way to see this is to check the "jensen" emblem that lights up. If you dont have enough power it will appear dim and only the right side lights up. Also the amplifier will not work if your speakers are "blown" even a little bit. Ive taken speakers that wont work on my lxa400 and connected them to a higher power amp and they will work (although they will sound horrible) If youre smart you will keep the gain under 3/4 on this amp, I see some people have found out the hard way that full gain fries the amplifier circuitry. Not an expert on electronics but it smells somewhat like melting glue or plastic. Ive noticed a lot of people have problems with the RCA jacks as well. There are 8 jacks, in two clusters. The first one is A+B and the second is C+D. Note: You do not NEED Y connectors on this amp! Connect your output rcas from the deck to top left and bottom left jacks of the left cluster. This will give you left and right (a+b) output from the first set of speaker outs. Then connect an rca patch cord from the top right and bottom right jacks of the first cluster and connect the other end to the top left and bottom left of the second cluster. This will give you output from the second set of speaker outs. Remember that this is in 4 channel mode. I dont remember the set ups for 3 channel but two channel I believe is the left deck rca goes to top left of the first cluster and the right deck rca goes to the top left of the second cluster. Then you just wire the speaker outs according to the picture on the amplifier. something like this: _________________________ |(+) - (-) +| ~~~~~~~~~~~~~~~~~~~~~~~~~ Speaker + goes to (+) and speaker - goes to (-) Also addressing another issue if you want to increase the wattage to your speakers you just use a lower resistance speaker (2ohm instead of 4) I would not recommend using anything over 4 ohms. As for the high level inputs, I dont recommend using them unless you have the plugs that go with them, its a lot easier to wire your deck rears to a line converter (changes straight speaker wire to RCA jacks) or to just buy a new deck with RCA outs. Last item, common knowledge: 400 watts does NOT mean 400 watts!!! This amplifier puts out very little actual wattage (50 or 83 per channel depending on the load) Hope all this helps someone out there.. Anyone who knows the 3 channel setups I would appreciate it.
