What time are you starting? I'll be at work till 4ish most likely

 

Starting soon. Working until noonish and then start back up tomorrow. Have a few school stuff for kids tonight and tomorrow. Might take me three days with other things going on.

 

Did you ever figure out your sub issue?

 

Yeah, there was too much power coming from the head unit and then it would go into protective mode. Works great now.

 

To much power from the HU to the sub?

 

To the amp, I must've turned it up by accident when messing with the HU.

 

If your still working Wednesday I can probably help out if work doesn't force me in

 

I should be able to swing by for a bit a little later. Gotta knock a few things out around the house

 

The only thing the HU sends to the amp is up to 4v of power though the RCA's. That doesn't make the amp go into protect mode even if you have it at 100% volume. Your amp's gains are too high, or you have other issues like a bad ground wire, incorrect sub wiring, or something to that effect. Most of the time people turn the gain up like it's the volume knob, the amp starves for power (drops below 12.1v) and then it goes into protect due to power loss.

Most HU's I test with my O-Scope can go up to 100% volume and send out little to no distortion (until the features are turned on like loudness+ or extra bass blahblah). This means no matter how hard you have your HU the amp should never go into protect mode if it's setup correctly.

The reasons amp's go into protect mode typically is due to:

1. Bad ground
2. Too much gain on the amp which it then starves for power from the battery and goes into protect mode. OR the amp is detecting clipping and going into protect mode.
3. Overheating (bad install location or not enough power from battery)
4. Incorrect wiring or insufficient wiring.
5. Amp is dying/dead

Not sure what equipment you are running but if your gain on your sub amp is past 50% it's not correct. If you are running class D amps, remember the D stands for "Dirty". (Well not really but they don't send clean signals) and if you are near the 50% mark odds are you are living in distortionville which may be the reason you are going into protect mode.

 

I'm going to have to look at it a little bit more closely when I get off. Thanks for the info this'll come in handy.

 

Cool. I’ll be at it until I have to get Harper.

 

Good luck. Hit me up if you got questions.

 

poor mans brisket!

 

.....

 

Did you technically roll yours? I thought yours just laid down for a nap?

 

Rolled a trailer and yeah just flopped the truck on its side.

 

Guy must not of owned a black light too check things out first, you dodged that bullet.

 

Got her.....
