Amp goes into protect right away, Help!


Recommended Posts

If I'm not mistaken, I've heard multiple times that a unibody car, you cannot ground to as it "doesn't have a chassis"?

I don't know, but you may want to ground to a strut tower or a battery; if you have a battery in your trunk. Just throwing that out there.

Sorry if I'm unhelpful. :(

Are there any subs connected right now?

No, NOTHING connected, just the power ground and remote, and i even tested it with just power and ground with a jumper instead of the remote to see if there was a problem with that. NOTHING. Instantly protects.

Even if u couldn't ground to a unibody chassis car, there is a 0 gauge wire from that ground point i made to the battery. And besides, you can ground to the chassis, that's how the battery makes a connection to the engine block/alternator, stock. also, the strut tower is a good ground, BECAUSE it's attached to the chassis. Thanks anyway tho.

On a side note, is it normal that if i put the DMM between my +12 volt terminal on my amp, and my remote terminal, it reads 12 volts? like the amps remote terminal is grounded? that could be totally normal i'm just wondering.

A unibody car can be grounded just like anything else.

has the amp ever got hot? what guage wire are you running?

i had this same problem but i had the wrong size wire and it actually melted the solder in the fuse (didnt appear to be blown at all)

No, the amp has never been hot to the touch, in fact it's usually quite cold cause it's in my trunk and it's winter lol. And i'm using 4 gauge, that's the biggest the terminals on the amp will accept.

ahh ok do you have any electrical updates? big three? batteries?

0 gauge big three, but even before that i was running this amp fine at 1/2 gain. Then it was fine with the big 3. until this happened, now even with the gain all the way down, and no music, no RCA, no speakers connected, it protects right away. I never dropped below 13 volts if that's where you were going with this..

Thats absolutely NOT normal. If you put one terminal of the dmm on the (+)of the amp and one terminal of the dmm on the (rem)of the amp you should NOT get any reading on the dmm.

i resolve to be a nicer moderator.

Is your amp grounded to the battery or body? If to the body, did you sand the paint down really well? There is a chance that turning the gain up pulled more current and it grounded through the remote if the ground wire connection is bad.

Good to know. Then what could have caused that?

The amp is grounded to the same spot on the body as the battery. so even if the chassis connection wasn't great, the connection to the battery is.
