Thumping speakers - no power light is on - wired correctly

I just installed this amplifier Visonik VB212PKG RMS condition is 4ohm - 200 W per channel, 8 ohm - 100 W per channel CONNECTIONS MADE -10 GA power 30A fuse - no capacitor used - GND made & checked - control wire connected from stereo amp control - connected to Low input (from Rear Pre-amp out from stereo) - (18V power verified) - regular stereo speaker connections (8 ohm) per channel - 120 Watt speakers per channel Everything is connected correctly to me. 1. The Red "V" light is lit 2. The GREEN POWER light will not come on. 3. The RED PROTECTION light is lit constantly. 4. The speakers only thump like a heartbeat every one second - with no music sound. What is wrong?

The amp is going into protect mode due to something wrong in the amp or some thing in the wiring to it ooh yea if you are getting 18v power to the amp that is way to high it should not be higher then 15v if the amp is in protect mode it will not play at all.

What is the actual watts per channel @ 8-ohms and 4-ohms on the Behringer PMP3000?


Those specs would be right - I have this same board but the amp was fried by a previous owner. I pulled the amp board out and tossed it and use the mixer now to drive an external amp. Great board. This amp is rated at 1200W "peak", bridged into an 8ohm load. That would equate to about 900W RMS bridged into 8ohm or 450 per side into 4ohm loads per side. You can't daisy chain all 4 speakers....impedance would be too low. You can run two of your 8ohm speakers per side - that results in a 4ohm load per side for the amp. That would give you amp delivery of 450W per side. Your speakers are rated to handle more than that so you're fine. For the record.....you could run one speaker per side no problem....just lower power output.

Hifonics colossus-ltd dual monoblock amp does not have much output, running a cerwin vega stroker dual 2 ohm sub wired 4 ohm load bridged


Bridge at 4ohms your only getting 600watts rms. You will need to bridge at 1ohm (parallel) and adjust the gain accordingly. This will give it 1600 watts rms. If you would of had a dual 4ohm sub, then you could of bridged it at 2ohms mono, but you can't you have to go either 1 ohm or 4ohm. I believe it's not getting enough power.

I have a plad213 what load impendance am i running it i hook up 2 4ohm speakers in series bridged on that amp and how many watts RMS am i getting per speaker


2 4 ohm speakers wired in series is 8 ohms and then is dropped back down to 4 ohms when you bridge it.

2 4 ohm speakers wired in parallel is 2 ohms then dropped down to 1 ohm when bridged
(most amplifiers will not handle loads below 2 ohms)

hope this info helps

    How do i hook up my amp. the ground wire and the v 12


    well, basically... the 12v (+) power wire is fused and hooked to the battery and ran to the amplifier, then run an amp turn on wire from you radio its usually blue with a white stripe (if you have an after market radio) then run the rcas from the radio to the amp and finally tap the ground (usually and cleaned bare-metal on your car close to the amp).... if you give me some more info i can help u further... what is the make/model/yr of your car, what radio do you have, amp, sub, speakers, etc....?

    Amp wont turn on..Visonik vb212pkw


    Well you have a high impedance path to your amp. If you have an inline fuse that should have blown. Car batteries don't have a current limiting feature HA The only explanation would be that the amount of current passing through the wire is causing a large voltage drop due to a large impedance. What gauge wire are you using? Here is an example.

    18 ft of 8 gauge wire would have to be passing about 400 Amps of DC current to yield a voltage drop of that magnitude. The wire would melt and all hell would break loose. So there has to be a break in your wire somewhere.

    Car Ampli Problem


    forget hooking this on a subwoofer. this amp produces only 50 watts per channel at 4ohms or 70 watts per channel at 2 ohms RMS...
    If you try bridging the sub, it will only give out maybe 100watts bridged.
    So..... if your sub is, lets say 1000watts RMS, youre just going to bust your amplifier to smoke...
    Find a more decent and powerful amp. This amp is only intended for separates and lowend subs with an RMS of 80 to 150 watts
