Chaining may be causing the problem. It sounds like you have the remote turn on lead and the ground lead connected together. They should not be this way. The remote turn on lead should be connected to your head unit's remote turn on lead or a source that is turned on and off by the ignition.

SOURCE: 2000 watt legacy predator amp

Disconnect all speaker wires from the amplifier's speaker terminals and disconnect the RCA cables from the amp. If the amp still goes into protect, it probably has shorted output transistors.

SOURCE: sub for lanzar mxa 282

Answer: Any subwoofer(s) that you can fit or afford that can handle 2000 watts. Just don't bridge that amp to try and push all the wattage to one because you'll be putting 4000 watts into a 2000 watt subwoofer. Run each channel into seperate 2000 watt subs or bridge to both. PIONEER PREMIER 3000 WATT subs would be perfect because they're quality and only about $125 US $$ each.That way if you wanted to upgrade to a better amp (Lanzar is ok, but not the best clean wattage) you won't blow the 2000w max subs with a power surge if you don't have a huge capacitor. Hope that helps. W ho's the insult guy? Totally uncalled for, but I'm sure you'd have some sensible and logical insult for me for saying that wasn't right. Some people get a good deal on a component and build a system around it or more commonly they buy an amp knowing what they want to push for wattage and get the subs next. Where is it written subs must be purchased first? Actually I'd rather buy the subs last so you don't blow them by getting an amp too much for the subs you already have to handle. You can blow subs with an amp, but you can't harm an amp with subs so it's actually better to have the amp first and get subwoofers that can work best with it. So anything 10" to 18" that can handle 2000 watts, at least 1500 minimum RMS. The pioneer premier's are great and sound awesome. JL Audio, MA Audio, MTX, Rockford Fosgate and Audiobahn all carry great subs at competitive prices that are worth the money and will last. Don't get anything cheap when for a few bucks more you can get everything you want, great sound, clean bass, loud as hell and will last.

SOURCE: humming noise in amp

You must break it down through a process of eliminating items. With the system running unplug the RCAs from the amp. Do you still hear the noise? Try turning the gain down on the amp a bit and increasing the subwoofer level on the head unit instead. Make sure you have a low pass crossover set (probably below 80Hz).
Does the noise change with engine RPM?
Try a different RCA cable. I find that most times noise filters will make the problem worse not better. If none of the above things work, check that the grounds within the car are good, battery to frame, to engine block and chassis. Sometimes a bad vehicle ground is the cause. If all else fails, hook it up to someone else's system and see how it works.

SOURCE: lanzar amp 1000 watt stays on protect mode

Hello snow11879,

I haven't been able to locate any support information online about your product, other than the email contact for support questions:

support@lanzar.com

If the amp stays in protect mode all of the time, I would suspect a short in the speaker wiring or speaker(s) voice coil(s), or perhaps a faulty ground. If it plays for a short period of time and then goes into protect mode, it is most likely overheating. First check all of the wiring. Test your speakers on a known good amp and make sure there are no places in your wiring where the insulation may have been damaged, causing an intermittent problem.

Many owners have reported that this particular amp has a tendency to overheat. Also, when run in bridged mode, the speaker impedance needs to be at least 4 ohms. It will overheat if the impedance is below 4 ohms.

Hope this helps.

SOURCE: lanzar 800 watt amp protect mode stays on

protect mode usaully means that something has disrupted the power of feed lines to the subwoofer/speakers possibly fuse is blown in amp or amp is blown in which we hope not. see if you have a warrenty if blown and send back or bring it to where you purchased it from.

Things to check: Is the wire between the amp and the subs heavy enough to pass 167 amps? 2000 * 12 = 166.66666 amps. Max volts on the subs are 10 volts....close enough. Are you sure you're using the line out on the head unit? You may be over driving the amp if it's anything else.If the head unit doesn't have line out connectors then you'll need to get an attenuator for each channel. Do you have caps on the 12 v power in wires? They'll keep the headlights from dimming and the alternator will last longer if you do.

2 12" subs + 600W amp. Turn on, goes boom once, then red light


Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.

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!!!!!!!!!!!

Red light


something is shorted in the circuit, or your subs. unhook the subs first and try it again, if it is still in protect then it is most likely the output transistors.
