Default Weird Problem

Ok so I have all aftermarket speakers in my car and an aftermarket headunit as well as 2 subs and an amp in my car. Well recently it seems that when i turn my radio up past a certain point...lets say 15..it shuts off, but anything under that is fine.....but when i get to 14 and 15 adn 16 it shuts off. What is going on?

Sounds like a blown speaker, or power issue

i dont see how a blown speaker could shut everything off. i'd guess its the amp safety thinking its drawing too much power. how powerful is the amp? how did you wire its power?

Def not a blown speaker, all the speakers are brand new. The amp is 800w and its connected to the battery. It has never done this before, it used to only cut off if it had been on very loud for a while then it would shut off. Now if I turn it up past 14 it shuts off then turns back on and etc..

I had an issue last night with mine doing the same thing... but I have not gotten it to do it again. Ive heard people say a bad ground to the head unit.

I have Powerbass 3XL-60C speakers (4 woofers/4 tweeters) 2 L-4002 powerbass co axials in the trunk and a S-10 10" powerbass sub powered by a kicker 400.1 amp. I had the volume at about 20 and the head unit like rebooted it self... it was so damn odd. but i cant seem to get it to do it again. my headunit is an Alpine CDA-9847 btw

Mine should be grounded right, I am pretty sure it is. But I honestly don't know what it could be, btw we have the same HU

haha nice I love this headunit to death. The amber color matches my gauges

Im pretty sure mine is good too. if it does it again im going to double check. It might be because my speakers are not ampd... but that issue never came up till last night when i installed the sub *shrug*.

sounds like it could be something with the hu design if you both have the same. thats a pretty big coincidence.

A blown speaker, or pinched speaker wire, can cause te radio to shut off via a "protection" mode. it may not be ur problem byt in the past 6 years as a car audio installer for a proffession, not just fun, its very common cause of a radio shutting off at volume.

I never had a problem till i hooked my subwoofer up. I think it might have something to do with the head unit internally or something

protection mode
Is the amp overheating?

What exactly shuts off? Are the speakers amped or are they running off the H/U?
