Ridiculous engine whine.....

[Cashdollar2009]

I have recently install a Hifonics Hfi100.4 as well as a set of Fosgate T1 5.25 components in my doors and sail panels, and dropped in Fosgate T1 3-way 6x9's in the rear deck. If need be I will get pictures to explain the wiring. Amplifier mounted to back of back seat, with seat down at all times. (trunked car, sealed off from trunk) Basically the rear channels come out of the amp, and run down the back of the seat, up the corner behind the trim, and up under the rear deck into those speakers. Now the front channels run same as rears except they tuck under the top pillar/corner panel off the back window and run above the window line/roof panel to the front corner, then go down alongside dash into the crossovers in the kickpanels. From the the wiring is ran through the stock door grommet and into the 5.25 mid in the door, and up into the tweeter. (Obviously seperate wires from the crossover...) Here's a picture of the door panel off, not sure how much it helps but... Had to make a mdf door pod on the spot and cut up my sails for this:

Problems:

- Crazy ass engine whine

- Hear turn signals, switches, and light changes through speaker "pops"

- Makes nasty ass loud static shit noises when I open and close my doors

- Frustrates the Hell out of me as I can't figure this shit out.

- BEST ONE: When I put arm pressure on my center console and move it too the right, the whine/pop/static gets louder than my music, I mean volume 30 loud. But pushed to the left limits it back to ordinary annoying frustrating whine and pop.

Please send me suggestions... I have turned the gain on my mids amp back down to "0" again because I'm paranoid that this crap is going to ruin my speakers... and still get this whine shit. All help appreciated...

sounds like a signal issue

where is the signal coming from?equipment/interconnects/routing?

Fosgate RCA's from Head Unit to Crescendo.

Knukonceptz 4-Channel RCA's from Head Unit to Hifonics.

Both routed along floor between seat and side trim, under carpet.

The ONLY wire-touching occurring is the 4-channel RCA's are making contact with the Crescendo ground wire when I hide everything. Obviously all the wiring is in the jacket so I am unsure as to how much of an effect that 1 foot section touching makes.

Try another head unit, or run an mp3 player directly through your amp to see where is coming the noise.

I had the same problem, but it was a blown pico fuse in my Pioneer h u. I fixed it, and no noise again.

first , I put all my rca's behind the h u to a good ground, and most of the noise went away, but it wasn't clean enough. I took care of the internal fuse and it was all good.

good luck

Wow. I Ran a ground wire from one of the channels of my rca's to a bracket behind the head unit. Only noise is a very faint hiss if you put your ear to the tweeter with the car running... I wasn't expecting this as I have NEVER in my life experienced or heard engine whine this horrible before.... Problem solved well enough for me. Thank you for your suggestions notorious. I really appreciate it.

Glad I could help you.

I did not know Kenwood h u had that problem too.

I had this same problem with a Pioneer head unit, I was re grounding everything until I tried the RCA jack itself. lol

My old kenwood needed their rca outs grounded, PITA
