I have a 10inch subwoofer in my truck and if I turn it up over a certain volume the sub and amp shut off. Is my amp not powerful enough?

 

No- the amp goes into protection. You simply made a mistake while wiring.
Heres your personal check list:
- Check all wires and cables for proper connection.
- Check the ground connection is the grounding point clean and bare metal?
- Do you have the appropriate diameter for the amp?
- Check the remote line for proper seating into the radio and into the amp.
- Check the speaker connections! Are they connected into the right connectors! ( this might be the point to look first!)

Your description sounds to me like a wrong speaker connection. Please describe the speaker and how you have connected it.

Welcome to the site!

 

Sounds familiar to me too. When the speaker impedance was lower than the amplifier's stable impedance, I always got similar amp behavior.

 

Thank you! I switched the wires around and cranked it up, sub stayed on entire time. Appreciate the help guys

Deezel, im still having cut out issues just not as frequent, whats my next step I should do?

 

Are all the connections, ground points good ?

 

x2 it's going into protect. From my experience, in that situation it's from low voltage. How many amps worth the fuses are on your amp? How big is your wiring? How long is your power lead from battery to amp?
google "the big 3" for car audio. Make sure all these connections are good.

If you get a good grasp on amperage, how much you are actually pulling, what all your components are rated for, and you verify everything is up to spec, a capacitor will probably help. However, a lot of times a cap is a bandaid though, and if your pushing spl that hard, you need to start designing more of the vehicle around it.

 

All points are still valid.
Without knowing the speakers impedance and the amp brand, being capable to drive the speakers impedance we can not make any progress.

 

I got an honest question here... I've done quite a bit of installs in my past... Why would the polarity of the speaker to amp make a difference as far as clipping (or protection) on the amp? I understand for certain reasons, the polarities need to match for sound waves and such, but why would it cause clipping on the amp side? I'm curious...

 

Deezel i found my error, battery connection was bad. Tightened the connections to the battery and fixed the cut out problem plus truck starts alot better after tightening battery cables

 

Great to hear you found the problem! I had a similar issue when I bought my truck. The seller thought the amp was going out, so he didn't ask for any extra money for it when selling. I found two loose screws that hold the fuse into the fuse holder for the amp power. It's never skipped a beat sense.
