Question about Lanzar VIBE266 Car Audio Amplifier

1 Answer

Subs Won't work when wired

I recently purchased a Lanzar VIBE286 amp and two Pioneer Premier TS-w3002spl subs. I have 4 gauge wiring running from the battey to the amp with a 120w fuse in-line about a foot from the battery. Also a capacitor near the amp. My ground is directly to the frame (made a hole and connected it with 2 ga wire. When i have everything hooked up and nice and tight it goes for like 2 seconds then the subs start what looks like backfiring on themselves. I can't think of what might be wrong because all the connections are tight. If you have any ideas fill me in

Hi,

Based on your post/description, pls try:
1. running the amp's power without the capacitor;
2. manually trigger the amp with the head unit off. Run it an determine if the backfiring still will occur (even with the head unit off);
3. temporarily interchange the left/right wiring;
4. temporarily interchange the + and - speaker wires;
5. run the amp normally trioggered by the headunit but remove the RCA connectors towards the amp.

If your concern has not been corrected or diagnosed which is at fault (wiring, amp, source) after completion of the above procedures, the amp may require an internal look and see.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FIXYA.

I have a Lanzar 4000 watt amplifier hooked up to 2 12inch MA Audio subs. When I crank my car the green power light on the amplifier comes on, but after a second or two it changes to protection mode. I have...


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Time to get an old school Opti Drive. .A thumbs up would be greatly appreciated if this answer is helpful to you. lanzar-4000-watt-amplifier-hooked-up-2-shonxoarcym4awy4zl1imx4o-2-0.jpg Lanzar

To get the most power what is the best way to connect paraelle or


run them straight and dont use the cross over. One speak on right channel and the other on other channel. Then turn up amp settings 7/8 the way up and control the rest from your dvd/cd player. I recommend some monster cable which is very thick. Ground the amp directly to trunk bolts but make sure to scrape the paint off or the connection will be bad. You can also use a cap which will send battery pulses to amp much quicker.

I have a 650 watt lanzar vector amp hooked up to 2 1500 watt sony subs. my amp is turned up half way and it frequently shuts off and the red protection light comes on.


the problem is that you must have your subs wired to a lower impedance than the amp can handle. Wire your subs to 4 ohms, or get an amp that can handle 2 or even 1 ohms and crank it and enjoy!!!!!!!!!!!

Hello stingerman20,

Your Directed D2400 amp is CEA2006 Compliant. It is stable at 1ohm and will produce 1,200 watts into that load. So you want your subs wired as close to 1 ohm as possible.

The only 3500 watt Pioneer Premier series subs I could find were the models number TS-W3002D2 and TS-W3002D4 with dual 2ohm and dual 4ohm voice coils respectively. The wiring options for the D2's result in 0.5ohm (too low), 2 ohms, and 8ohms. Your best option would be the 2ohm configuration which would be voice coils in series and subs in parallel. Options for the D4's result in a 1ohm load and a 4ohm load. Your best option would be the 1ohm configuration which would be voice coils and subs parallel.

To see the wiring options, try Rockford-Fosgate's "wiring wizard".
Select 2 woofers and the appropriate voice coil impedance and quantity and click "search". It'll bring up all of the possible wiring configurations along with the final impedance load.

Hope this helps.

No power


You probably have ONE of the speakers wired out of phase.

If the speakers are wired correctly, you may have the crossover set to high pass instead of low pass.

Let me know if you have any other questions.

How should I wire my 3 subs to the 500/1 amp???????


First of all how many ohm's are each subwoofer rated at . Are the subwoofers dual voice coil or single voice coil. Once I know that I can help you. I think the JL amp is not recommended below a 2ohm load.

3000 watts divided by 12 volts=267 amps...how hot is your alternator...have you considered a separate alternator or a battery isolator?

hi there. ill start with the wiring. you should have a blue remote lead going to the back of your head unit, the power cable running straight from the amp to the battry, the earth should be earthed in a fairly decent place, any metal inside the car realy, and then your wires pos and neg from the amp to the subs. the reason why the kenwood might not have much base on it is to my knowledge, there should be a switch somewhere on the amp that will increase or decrease the power input for the speakers, if this is set very low then hense why theres not much base comming from them. if the amp is on and its giving something to the subs it probably isnt the wiring. try checking the amp for the switch first, if you cant find it try the pioneer amp and see if theres any diference.
dont hesitate to contact me if you get stuck


cheers, adam
