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

Does this boss chaos c550 amp match up to perform correctly with 2 12inch kenwood peak power 600 watt magnet 500g (17.6)oz impedence 4 ohm kfc-w300s speakers

It's not bad, but at 400 watts, it's a bit underpowered
It'll be plenty loud, but the amp will distort before the speakers do, particularly if your subs are wired in parallel (as dual-driver boxes are typically wired)

Listen for distortion, and turn it down a bit if the sound gets fuzzy or static-y sounding

All amps aren't created equal. More exspense amps put out "cleaner" power. You need to know what the RMS power rating is for the amp at 8 ohms and 4 ohms. Also, is the speaker an 8 or 4 ohm speaker? How you wire a speaker or speakers (series or paralell) can change the ohms (resistence) which will change the power put out of the amp. Also, I'm assuming you are setting it up in mono?

Bought some 6x9's now need an amp to power them up cause my headunit is weak.. umm any advice on what amp to get.. i only need to power 2 vibe qb69 6x9s so do i need a minimum 2 channel amp? hope you can...

I know this is a very broad statement, but your budget will allow for what you buy. You will want a nice 2 channel 50 watt rms amp min. 50 watts is a lot of power for those speakers and you will be happy. I would recommend if your budget allowed a nice kenwood, Alpine, Diamond Audio or MB quart. Just make sure whatever you buy that it is a low noise A/B class amp. Nothing to special.

Take care and have fun!!

Usally a ground loop isolator will fix that problem. It plugs into the RCA's between the radio and the amp.

Try to reground the amp in a different spot.

Or run a refrence ground from the deck to the amp next to the remote turn on wire. (still keep your main amp ground hooked up)

DO NOT run your power wire next to the RCA's, that will induce a field which in turn can cause that buzzing sound.

When the bass cut on the speakers cut off

220 watts RMS x 1 at 4 ohms (400 watts RMS x 1 at 2 ohms)
the amplifier may be over-driven. are there red protection lights coming on the front panel? Or a loose wire - power, ground, or speaker.

400 watts delivered to 300 watt speakers the only way to do this would be to wire two subwoofers in series so that the power needed to drive them will be 600 watts to max, however this will increase your impedance on the speaker (8 ohms) load so what you can do to compensate is get an 8 ohm 600 watt resistor and put it in parallel with the speakers you will then have 4 ohms of impedance at a total capacity of 600 watts of power In other words the amplifier won't blow these out now.

Hi Trim God,


I do not reccommend that you push the Pioneer speakers over 100 watts.  The jenson will already drown the car with bass through your pioneers so much you will want to turn off the bass boost when playing some low bass hip hop songs. It changes from one venue of song to another, so I just keep the jenson bass boost off and use my head unit to adjsut the sound to fit my listening prefences. I am telling you man, you will be blown away .  Hook up the pioneers straight to the Channels,. do not bridge.  I put Subs in my truck though.  I used the Pass output to send the audio to me Jenson 2 Channel 600W amp. I drive one 10 inch enclosed JBL Class A/B Sub. I bridged the output of the 600 W amp to the 10 inch sub  in my Z28.  The pioneers never get drowned out.  I did smoke my 2 channel Amp one time. and also took out a MTD 10inch sub. I am talk shooting flames and smoked the whole car up. I think if you bride the XA4150 to the pioneers, you will have the flaming smoke problem in no time.

Car amplifier weak

if you have a 25 Watt amp (per speaker) then go to radio shack and get (2) 50 watt resistors (8 ohms each). attach them like speakers. turn it on half volume. they should get quite warm to the touch.
