i just install my clarion DVD player

i hear the rpm in my tweeter not very lound but i hear it!

it just started when i move my new batterie in my trunk

is that a bad ground?

thx

 

alternator noise = bad ground in the HU...re ground it...

 

only last question

what is HU?????

 

head unit

 

Why did you move your battery to the trunk? Are you running two battery's?

Did you use an isolator and proper gauge cables. -- If it was not done properly, it could cause alot of problems --- more than just noise in the tweeters. Im not trying to scare you but, seriously, if not done right, your car can catch on fire.

 

i am going turbo
so i have to make place for it under the hood

cable gauge 4

 

Are you using the same original grounding point under the hood?

 

no all ny new wiring in the trunk with gauge 4
