Quick Question

[tylork92 10+ year member]

Just installed all new hifonics zeus series speakers 2(6.5 comps) and 2(6x8's), and I'm running a hifonics 4 channel amp. I only have the front two speakers amped, until I get another head unit with more outputs.

Anyway I had my door panels off earlier when I was fixing rattles, and my tweeter wires both touched the door and shorted out. Made one hell of a screaching sound.

The front speakers sound fine with the key turned back, but when I cranked the truck I found that I now have alt whine.

So where do I start..

Thanks for any help

One of the most common causes for alt whine is due to the amplifiers power wire and the HU's rca's being ran down the vehicle NEXT to each other. Not cool. First I would make sure that the RCA's are not running across or next to any source of power. Second, if this just occurred when you shorted out the tweeter, you might have shorted out something in the amp to cause it. Also, make sure all your ground connections are clean and free of corrosion or buildup of any kind. You always want ground leads touching BARE metal. When in doubt, wire wheel the hell out of it!! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Thanks alot for your info....Even tho i kno the basics of wiring such as not letting power wires and RCAs cross etc. (this is the first thing i checked as its not in my truck and im not the one that wired it all up.) Nice to see helpful people are left around here. I knew it had to be the amp or HU as a regular speaker still had alt whine. I did take the amp apart last night to see if anything was burnt and yep sure enough 2 of the resistors are burnt. Now gotta try and find someone locally to fix it or send it off.
