Question about Lanzar VIBE286 Car Audio Amplifier

1 Answer

No sound Power (12+ volts) is getting to the amp. All lights are on. Low level (RCA) signal is good. But no sound and very little power (2-3 volts) from speaker terminals. It was pushin the set of Power Acoustk 12" FUBAR (dual 4ohm voice coil) great. Had been working fine for almost 30 months, until I upped the volume higher than ever two nights ago. The amplifier was still operational when I parked later that night. The "protect light" was on the next day so I double checked all the connections. Is the amplifier toast? Is it troubleshootable? The stock alternator on my 06' Camry is horribly lacking the amperage output nedded to satisfy the electrical draw of my amplifiers. I have a 5farad cap that helps alittle. Can Anyone Throw M Some Knowledge A bout What To Do Next?

    Ok, I tried the 12 hour disconnect. Still the same condition- All lights are normal no "protection light". The speaker terminal output is almost nil. I've got this nagging feeling that it is something simple, but if I have to sauter some capacitors to the circuit board, I will.

    Any additional help would be a God-send.

Try running the amp without the speaker wires hooked up. See if the light is still on. If it is still on, the disconnect all power to amp for 12 hours. This should reset the amp. Then try again without and then with the speakers. This should fix the problem. If the light is still on, that means a capacitor inside could have overheated and fried the output.

    does it work without having the cap hooked up?

    try using the next higher amp fuses on amp and in wiring. Also make sure your rca are working good and hard hooked up to the " rear ouput" on the back of the cd deck.

    oh ya, THE THICKER THE WIRE THE BETTER  because then it draws and sends power power and wattage. especially for battery and ground

VR3 200 AMP

Looking at this picture you can see the terminals at the top.
This installation has one speaker hooked up on the right, and the power inputs hooked up on the left.
The inputs will be power on the left, 12 volts positive (V+); a signal wire for to power on the amp that's 12 volts positive too, (V+, It's usually a yellow wire that comes out of the car stereo called To Antenna, or To Amp. and the third connector on the left is a Ground, or 12 volts Negative (12-). Look for the labels V+ and V- to get the power connectors in the right places. (I can't tell from the picture which is which)
On the left side is the Speakers, Each speaker has a positive and negative lead, and the terminals on the amp are labeled Left + and Left - and Right + and Right - .
Align the speaker leads to the terminals (in cars a negative lead usually has a stripe running along the length of it, and a positive has no stripe).

On the other side of the amp are RCA sockets, one red one white. Any low signal can plug into these, from an Ipod to a turntable. Your car stereo, or EQ, will have RCA outputs that can connect to these with an RCA Patch cord, which has plugs on both ends that will fit into the RCA sockets. Whatever signal goes into the RCA inputs is amplified out of the speakers when it works.

Amp comes on running 2 12" 450 watt pioneer subs, volume only seems to be about half output, with speakers bridged

This could be the reason. If you look at the specs for this amp you will see that the continuous power out is rated for 380W bridged. The speakers rated at 450W should be able to handle close to 315W continuous. Now if you split these numbers being you have bridged these speakers, you drive each one up to about 190W continuous. The speakers are being driven approximately by 60% of the rated capability. I personally like to keep it right where you got it, not exceeding 80% of the speakers rated capacity.

Here are the specs for the AMP:
  • Specifications
  • Peak Music Power 760 Watts
  • Number of Channels 2
  • Load Impedance Capability 2~8 Ohm (Stereo), 4~8 Ohm (Bridged)
  • Continuous Power (4 ohm) 125W x 2
  • Continuous Power (2 ohm) 190W x 2
  • Continuous Power Bridged (4 ohm) 380W x 1
  • Frequency Response 10Hz ~ 50kHz
  • Total Harmonic Distortion 0.008%
  • Signal-to-Noise Ratio 100dB
  • Dimensions 12" x 2-3/8" x 12-3/4"
  • Features
  • Bridgeable
  • Channel # Capability 1/2/3
  • PWM Regulated MOSFET Power Supply
  • Screw-Type Speaker Terminals
  • Balanced Isolator Input Circuit
  • RCA Inputs 2 Channel
  • Input Level Control Hi-Volt (200mV ~ 6.5v)
  • Built-in Crossover Selectable LPF (80Hz, -12dB/Oct.)

    No sound from speakers, but there is power to amp

    make sure the power wire and the remote wire have voltage. at least 12 volts. make sure the ground wire is good and has a good solid ground. after that make sure the rca cables are getting signal from the radio. if you have a small speaker or tweeter you can touch the wires from the speaker to the rca cables and it should play music very quietly. meter the subs and make sure theyre ok and not shorted or bad. if all that checks out good.... the amp is probably bad. start with all the simple stuff and work youre way up. if the amp has good power and signal and good speakers then the only thing thats left is the amp. good luck

    Does an mp3 player put out enough power for input to KAC-624 amp?

    Have you connected the rca plugs to the radio or amp directly? If you've connected it to the radio make sure that the input level controls are adjusted AND available on that model (it will say AUX, INPUT, SUBWOOFER, REAR, etc.) Connecting your mp3 player directly to the amp will not have enough juice to hear sound you need to connect it to the radio first.

    Hello korre,

    Low output could be the head unit, the speakers of the amp itself. Start by isolating the problem.

    1) Test the sub(s) on a known good output.
    2) Input a known good signal. A portable with RCA preamp outs will work OK.
    After you have eliminated the other components, troubleshoot the amp itself:

    1) Check the onboard fuses. The M605 has 2 each 30A fuses just to the left of the power and ground terminals.
    2) If it was just installed, then my first suspicion would be a problem in wiring. If one tiny little strand of your speaker wires comes into contact with another wire or ground point, it could present just enough of a signal path to ground out most of your power, and perhaps still allow the amp to seemingly operate normally (at least for awhile). Check power and ground too.
    3) Make sure your head unit RCA's are plugged into the inputs and not the outputs.
    4) Check the low-pass and subsonic filter settings. If low pass is turned all the way down, the amplifier would ONLY send frequencies below 30Hz to the speakers. Subsonic turned on and the low pass all the way down would effectively result in no sound.
    5) Remove the top cover to access the mode controls and display. Check the input level.

    If everything checks out, the amp probably has a defective component and needs factory/service center repair.

    Hope this helps.

    Hello herb31,

    It sounds like there is a difference in the signal levels on the inputs to the amps. You did not specify what the RCA's are connected to on the head unit side. If they are connected to a stereo pair of preamp outputs, you may be able to solve the problem by using only the channel with the higher signal and use an RCA "Y" adapter to split it to both amps. If they are connected to a dedicated subwoofer output on the head unit, make sure that the head unit is set for "subwoofer". Some less expensive head units, I know JVC in particular, has only 1 set of line outputs and requires you to go into their "PSM" (Preferred Setting Mode) to set the line output mode and if you select "subwoofer", then allows you to select the low pass frequency.

    If you are converting speaker-level outputs through a "line out converter", check both the input and output levels.

    Also, if you are splitting an output from the head unit, you still need to connect 2 RCA's to the amp inputs. The signal will be properly split if you use a 1-female to 2-male "Y" adapter. To feed the same signal to both amps, you would need 3 "Y" adapters. Feed the output signal to the female end of the first "Y", and plug the male ends into the other 2 "Y" adapters. Then, the 4 plugs you have left on the ends go into your amp inputs.

    Hope this helps.

    Only door speakers have sound on the cd mode

    the amp requires a 12 volt power constant, and a 12 volt "on" signal. you prolly have the 12 v "on" hooked up to the car stereo's antennae remote, meaning your amp gets power when the radio is on, cuase the radio is sending a signal to the amp (thinking that it is sending a signal to the antennae to raise)

    you do have one of those collapsable antennas, right?

    Power and Stand-by light alternate (JPA1150M)

    It shouldn't be going into protection mode. Have you tried doing this on the other channel?

    The high level input is for speaker level signal (as those you'd have if you were driving the amp from an OEM head unit).

    No power


    Other than the +12V, the ground (-) and the 2 RCA inputs, normally external amps have also a remote trigger which switches it to active on. The remote trigger is activated by a wire from the head unit. Colors would either be yellow or blue but depends on manufacturer of head unit. Alternately, you can connect a simple toggle on/off switch to activate the external amp.

    Additionally, pls verify that the 2 RCAs from your head unit are audio out and not audio in for aux source.

    Good luck and kind regards.
