hey guys.. i got a little problem with my CLS. I took out the factory speakers and installed some boston acoustics for my front and my rears. i have the power wire running through the driver side and the rca's through my passenger. i stripped off the paint to the metal in back of my backseat for the ground. i am currently using 2 amps. E series jl 400/1 and 300/4. i wired them all to the speakers. for some reason i have a whining noise that is intolerable. some advice would be great. Thanks!

 

What deck are you using?

 

im using the alpine 9827. i had that installed in my other cars and had no problem but i have problems with this car. im running roskate fostgate power, ground and rca's. it was a package deal.

 

It sounds like your deck is not grounded. A common install mistake on the TL/CL is not running a chassis ground to the deck. The factory deck is mounted to steel brackets in the dash. When you change to a single din aftermarket deck it mounts to a plastic dash kit. For some reason the ground wire in the Honda radio harness is not sufficient. This causes a ground loop. If you run a short ground wire from your factory radio brakets to the chassis of your Alpine you should be golden. Most CL/TL owners that have this problem also have a problem with AM/FM reception. The chassis ground should also cure that problem.

Good luck. Please let me know if that helps.

 

thanks for the help.. i will try to do that when its not 15 degrees out..

 

i tried grounding the head unit but it still doesn't work. is there anything else that you can think of to fix that problem? all the help would be greatly appreciated. thanks
