602Daddy Posted March 26, 2021 Report Posted March 26, 2021 I am running 2 15" subs in a custom box tuned to 32 hz. Im currently building a wall for 4 15's and i went to listen to the 2 15's one more time before i removed the box. When i turned the bass on it was VERY quiet and didnt sound like the subs were playing at all. I opened the trunk to take a look, and the subs were moving like crazy but barely any output. 10 seconds later my amp cuts off and theres smoke from the port. I later found that I had my rca's were wired backwards as well as i poked a small hole in the surround but nothing bigger than a pencil point. Anyone have ideas why my sub blew? only the one with the hole blew the other one is fine.
602Daddy Posted April 3, 2021 Author Report Posted April 3, 2021 Update!!! I replaced the blown sub with another one and the new one blew. So I did it again and same thing, the same sub blew. I am at a loss of words as to why one sub keeps blowing and the other one just isn’t affected. I ran these subs for months on end full tilt and have never had any issues till now. This is so discouraging I feel like taking everything out of the car and giving up. I NEED HELP
Dafaseles Posted April 4, 2021 Report Posted April 4, 2021 Have you checked your output voltage at all your speaker outputs? It sounds like your amp is having problems to me. Might be time to get a new one unfortunately 2011 Chevy Silverado under construction My build log here. Check it out!
1point21gigawatts Posted April 4, 2021 Report Posted April 4, 2021 Your amp isn’t tuned correctly and/or you head unit is clipping too. Tune gain correctly and filters correctly. I know you probably don’t think that because of you playing that amp on the same subwoofers for a while. But clipping from an incorrect gain and/or filter can affect a subwoofer after a few weeks or a few months, even if it’s the same subwoofer. It’s impossible to tune an amplifier without meters. It’s impossible to know the clipping point of a head unit without a meter. If you tune an amp on a head unit volume that is clipping, then no matter if you tuned that amplifier correctly, the head unit is sending a clipped signal to a clean tuned amp, which causes the amp to clip the subwoofers. Or the head unit is sending a clean signal and the amp is tuned wrong and clipping the subwoofers. Smd meters would help. “How can we help you?” “And don’t forget to tell them that the customer isn’t always right.”
602Daddy Posted April 13, 2021 Author Report Posted April 13, 2021 Im going to replace my headunit, amp, and subs and see how it goes. Ill make sure my gain is set correctly so im not clipping when i get the new products in. THANK YOU. I did not consider my head unit but you may not be wrong. Have a good one yall
