Question about Crunch V-Drive V-2800 Car Audio Amplifier

1 Answer

Amp goes into protect mode.

When i start my car my amp will go directly to protect mode, i can hear a small amount of music coming out of my subs but it won't hit. I was wondering if its the ground wire, a fuse blown, or if its touching the paint, I have 2 12 inch duals so i doubt the subs would blow my amp, any other solutions or tips?

Re: Amp goes into protect mode.

I would definately suspect wiring. If you can use a volt meter. Put it on the b+ to ground and see what the reading is should be 12+ then try the ground to remote wire should be 12+. If it drops below 12 volts when car starts. Recheck wires for loose connection. Also double check the wire you have the remote wire connected to. You might even want to disconnect from the amplifier and use a jumper wire from the positive terminal on the amp to remote on the amplifier and see if it stays on then. If it stays on you will have to find the loose connection or find a different wire to get remote power.

I have a punch p850.4 amp that goes into protect mode as soon as its powered up , have checked and double checked all connections to make sure its all hooked right . even downloaded the pdf for the amp .

I have exactly the same problem, try a different speaker wire from your sub terminal to your amp terminal, if no luck you may have a loose connection on the wires on your sub, due to vibrations etc they can sometimes come loose, but very rare. worth checking though. 1 loose connection can make the amp go into protection mode. If all of these are fine, start from the beginning, ( I have tried this and i think its my speaker wire shorted out) 1st dissconnect all wires from amp. Then connect ground first, then your live. then power up amp, it it works andd not in protect mode your earth and live are fine, then connect your remote, then test, then speaker wire , then test, that way you can rule out bad connections and find any fault.

My amp keeps going into some safe mode and red light blinks and stops base to my sub. I have it hooked up to 1 15.4 Orion HCCA.

The "safe mode" on your amp usually kicks in for two reasons - the ohm load on the sub is too low for the amp (presenting a "short" to the amp), or it's going into thermal protection because the amp is too hot. From your description, it sounds like there's a short in the wire, the sub's ohm load is too low, or the sub is partially blown.

If you have another sub or speaker, connect it to the amp's output and see if the amp still goes into protection mode. If the amp goes into protection with a known-good speaker, then there may be something wrong with the amp's power supplies. If the amp works properly with another speaker or sub, then I would check the sub that's causing it to short out.

You may also want to check whether or not the amp is over heating by just touching the amp when it goes into protection. If it's just warm, that should be ok - if it's hot, then it might be working too hard. In this case, you may need to check the input voltage (12-14VDC) and the size of the power and ground cables. If your ground isn't properly connected, it can cause weird problems like over heating, shorts, erratic behavior, etc...

My amp keeps going into protect

do you have the right size ground wire, relative to your power wire? If your ground is smaller when you turn it up there is alot of power it needs an exit and if the wire is too small it travels elsewhere maybe your rca, causing your amp to protect.

Cut out

rewire the subs-each sub you want in series=8 ohms per sub-then at the amp wire the two 8 ohm subs in parallel which brings the ohms back down to 4 ohms which is optimal for the amp and it shouldnt shut down on you any more-try that-good luck

If you power up the amp with the RCAs plugged in, does it go into protection mode.

Amp heats up and goes into protect mode

Hi Saint108. You're describing it well, and i know what the problem is already. The MA audio amp, can't hold with a 2 ohm load. It's too low for that amp, that's for sure. Those are budget amps and they are not well built enough to handle low ohm setups like that. It's overheating and there's no ways around it.. Other than wiring your subs differently ! Just wire your sub directly (not in parallel) in a 4 ohm load, you will notice it will stop overheating that much. Do it quick, you'll most likely fry your amp giving it such hard work !! The HUM you're hearing could be related to it also. Try that, and keep me posted on the status. Thanks ! Cheebster.
