Engine Noise?

[Fattony911 10+ year member]

Just installed a system with an LOC for the first time and everything is god sounds great everything. When we turned the stock hu off there was a deep almost like a tone of bass like a 30hz constant tone coming from the woofer that was really loud inside the car. So i don't know if this is engin noise how it can be fixed or anything. Should i try another ground? Is the quality of the LOC i pretty puzzled at this point.

Check if there's a loose speaker wire grounding with the body

nope, all speaker wires are accounted for...im so confused never had this before im gonna see if i can change the ground, but when i did the ground i prepped everything scraped away all the paint to bare metal and cleaned it with alcohol. It's a good solid ground if anyone knows of a better one in a 2000 toyota celica lmk

Sounds like a bad ground to me...Maybe on th HU?Did you run your under hood wires close to electrical stuff under the hood?It could be EM happenings their too.
