Kicker Speakers added to Alpine System

[Sparky2025]

So my buddy installed 2 4" kicker speakers to the rear of my JLU and a 400w amplifier, my Jeep has the Alpine system and when turning it on, the kicker speakers have a high peach interference. Anyone know how to fix this?

Does the noise change as you increase speed? If so, try adding a noise filter to the Alpine’s main power source. This is usually caused by the alternator. Check the wiring and the belt. If the noise remains the same, try checking all the ground connections for the radio, amp, and speakers make sure they’re making a good contact. Also, check to make sure you don’t have multiple grounds for the same device.

That’s about all I have…

Yes, you must remove them or they'll block the sound from the kickers. It's the water and sugar content that interferes.
