Alright, I've finished installing my system into my FC about a week ago, but haven't had the time to remedy the last bugs in it until this week (paid time off FTW!!).

So here's my system in the FC:

-Alpine CDA-9856
-TMA T360.2 (180W x 2RMS @ 2ohms / 110W x2 RMS @ 4 ohms)
-Alpine Type R Components (SPR-17LS) - (350W peak / 70W RMS)

Now, the problem, I'm getting a bit of an annoying 'buzz' through my tweeters. Is this due to electrical interference, or is this some setting I have to dial in on my amp? My speakers ARE getting more then enough power, correct?

Here's a picture of how my wires are currently sitting, however THIS IS NOT PERMANENT, i haven't had the time to shorten my +12V, nor mount the amp properly. So is my electrical wiring mess causing electrical interference with the wires, which is causing the tweeters to hum/buzz?

Also, last question, has anybody successfully mounted an amp underneath the passenger seat on an FC/FD, and if so, how did you go about doing this?

My wiring mess..................

 

Buzzing usually comes from a poor ground. Use a shorter ground for the amp and that should help.

 

My ground is mounted straight to the transmission tunnel (Existing ground). I'll check the distance in the morning though!

 

Like mentioned before, that "buzz" is a result of a poor ground. I had the same issue, mine was grounded to the chassis, I sanded where the ground was attached to make sure it was bare metal and havent had a problem since.

 

Awesome, I'll fix that tomorrow while I fix my passenger window for the 5th time.

Thank You.
