Speaker Whine

I know this is usually related to a poor ground, but I have it coming out of the rear speakers only. :glum: When this has happened, I have had the whine come from all speakers, so I'm lost. Any ideas? Also, is there a ground that is the usual culprit for the "whine"? I have already done the maintenance to the battery/strut grounds and the ones, by center console, are clean.

What he said. A lot of times the main ground that you installed or the factory installed can be good, but within a component of the system the ground can be going bad. Give us details on what you have in the car and we can help you troubleshoot.

What did you replace the speakers with?
Infinity References; components in the front, but only the woofer has been installed. In the months, to come, I'm planning to replace the head unit and amp, but in the meantime...no whine please. :lol

Are you the one that bought Ron's Infinity set?
Nope. :baller:

Not the 2 ohm ones? You only have the base system, not the Infinity System in the car now, right?

With your fronts - the way you have them hooked up, are you maintaining the 4 ohm load, or since you don't have all the components in, do you have some other rated load?

After looking at the paperwork, the fronts are 2.3 and the rears are 2.65. I "thought" they were 4, but was wrong. Sails are still the original speakers. I have the system with the amp on the passenger side. I haven't hooked the full components, because I was waiting until the new H/U and amp and have read it was pointless with the factory amp.

You going to aftermarket HU and amp, or another factory set up?

The difference in impedance may be where your whine is coming from - can't be sure, but I'd swap back in your old speakers and see if it comes back if you are worried about it. The lower impedance will allow a little whine in the amplifier to become a louder whine.

Aftermarket.

Original speakers were blown; literally no sound was coming from them. Isn't the factory setup 2 ohms?

I wouldn't worry about speakers being the issue here. There really shouldn't be any whine to begin with, so focus on eliminating that. You can bypass the amp and run straight off the HU and see what happens. If the whine goes away, it's the amp. If not, the amp is eliminated as a possibility.

Do you still have the factory HU? If you do you can try swapping that in temporarily to test if it's the HU.

Factory. I'll look into bypassing the amp, I just wasn't sure if there was a ground that usually causes this.

If you are going with aftermarket, I wouldn't fret with anything at this point.

Turn your volume down, and install your new head unit.

The factory systems are 4 ohm except on the Infinity systems.
Who drives with low volume? :lol I think I can only hear the whine with the radio off, but I'll get back to you on that. I have the Infinity system (7 speakers); 2 sails (putting component tweets here today..maybe), 1 center (blown so removed), 2 front doors (replaced), 2 rear deck (replaced).

I'll dig around and see if I still have the original speakers, but the amp says Infinity.

I bypassed the amp, which doesn't have enough power for the tweeters, and the whine is still there. I noticed, with the trunk open, that I wasn't hearing a whine. I found the whine coming from the driver side rear seat area, which explains why it was only coming from the rear. I'm starting to think the whine is something else.

Ah - yes - then it could be the fuel pump you hear...

Run the sound system with the car running till you hear the whine - then turn the key back from "RUN" to "Acc"... See if the sound stops.

The fuel pump is right under the back of the floor, where the sheet metal bends upward to form the trunk, under/behind the seat.
