Engine feedback in my sound system

Anyone know how to stop that annoying feed back sound that can jump into ones sound system?

I would check all grounds in your sound system from the battery, head unit, and amp if using one. Also, make sure your chassis grounds are snug, clean, and have good contact to metal.

The Outlaw is gaining momentum as a positive member of FTE.
Also check that all electrical wire is away from the speaker cable. But most likely loose ground.

If you are running shielded cables make sure that they are grounded out at the end furthest away from your speakers. Could also install a capacitor, my understanding is that it would dampen out interference noise.

If you are running a distributor with points then change the condenser, its job is to shunt those frequencies to ground (and prevent arcing across the points).

Do you have solid core plug wires?

also check your alternator for a weak diode, you can put a capacitor on the battery lead to smooth out any pulses in the current as well.

I agree. This is usually the cause.

Aside from the other good suggestions if you have a fiberglass hood it does not shield the ignition system. That is why 60s Corvettes have SS shielding around the plug wires and the distributor.

I had that issue and it was the solid core plug wires.

Hi Guys,

Sorry for taking so long to respond back with my progress. Over the last week I have been organizing myself so that I only purchase what I need and to make sure I purchase everything in 1 trip, well at least I tried too.

To reduce the RF I am going to first start with grounding the hood and changing the spark plug wires as I am sure the ones I have are not carbon core.

Will post an update once I complete this, I hope its today.

All done!!!! Man thanks for all the great tips!

Basically grounding the hood and installing carbon core spark plug wires took care of the problem!

With the new 1300.00 sound system pumping out some sweeeeeeet music the fun factor of driving the truck just went up a billion percent. Took it for a drive with my daughter yesterday and it was priceless ☺
