Review: Fixed the crackles and pops in my '96 Corvette -- cheap, well-built fix - After swapping the factory stereo in my '96 Corvette for an aftermarket head unit, I got annoying crackles and pops through the speakers—classic ground loop issue. This InstallGear ground loop isolator took care of it right away. Plugged it inline on the RCA cables, and the noise disappeared completely; audio is clean and quiet now, no interference at all. The case is plastic but feels solid and well-built for the price—connectors are snug, no flimsy vibes. Super cheap compared to dealing with wiring headaches, and it just works perfectly. No complaints; great little gadget for older Vettes with aftermarket upgrades. Review: Worked perfectly for alternator whine - I installed a subwoofer, door speakers and 2 amps in my truck. I also installed a cheap 10.1" android head unit. It sounded pretty good, but had terrible alternator whine. It made it so the system was unlistenable at low volume. I did the normal troubleshooting of checking my grounds, making sure the RCA didn't cross paths with any power wires, used a nice shielded RCA cable, nothing would get rid of that awful whine. I didn't have high hopes for this $10 filter, but figured it was cheap enough to give it a try. It worked flawlessly. The amp is now playing crystal clear with no hiss, whine or anything. Just a nice dead silent noise floor. No noticable impact on output or sound quality. Note, as another reviewer pointed out, the label seems to be backwards. The male RCAs plug into the amp and the RCA cable coming from the head unit plug into the female end. Installed in less than a minute and solved my problem 100%. ## Features - Effective Noise Reduction: This noise filter car audio eliminates humming and alternator noise, improving sound clarity for car audio systems; ensures a better listening experience - Simple Installation: The compact ground loop noise isolator fits most car and home audio setups, allowing for an easy install in just a few minutes; no professional tools are required. - Universal Compatibility: Designed to fit most setups, this car audio noise filter works well with RCA cables and stereo systems; compatible with various models for versatile use - Complete Kit: This kit includes everything needed to reduce noise effectively; the group loop isolator works with car and home stereo systems, improving sound clarity without signal loss - Ideal for Car Audio: The car audio RCA noise filter helps eliminate unwanted feedback noise, ensuring clearer sound quality; dimensions: 2 x 1.5 x 1 inches for easy fitting in tight spaces ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B077Y5DLBB | | Best Sellers Rank | #60 in Car Amplifier Noise Filters | | Brand | InstallGear | | Brand Name | InstallGear | | Customer Reviews | 3.9 out of 5 stars 2,955 Reviews | | Global Trade Identification Number | 00851714006983 | | Item Weight | 0.1 Kilograms | | Manufacturer | InstallGear | | Material | Plastic | | Material Type | Plastic | | Model | IGGLI | | Mounting Type | Freestanding | | Number of Channels | 2 | | Number of Items | 1 | | Part Number | IGGLI | | UPC | 789398416975 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** InstallGear - **Manufacturer:** InstallGear - **Material:** Plastic - **Mounting Type:** Freestanding - **Number of Channels:** 2 ## Images ![InstallGear Ground Loop Noise Isolator, Amplifier Noise Filter for Car Audio and Home Stereo, Feedback Loop Isolator, Car Stereo Ground Sound Suppressor, Reducer Alternator - Image 1](https://m.media-amazon.com/images/I/715R5RSiiJL.jpg) ![InstallGear Ground Loop Noise Isolator, Amplifier Noise Filter for Car Audio and Home Stereo, Feedback Loop Isolator, Car Stereo Ground Sound Suppressor, Reducer Alternator - Image 2](https://m.media-amazon.com/images/I/8185qVhE8-L.jpg) ![InstallGear Ground Loop Noise Isolator, Amplifier Noise Filter for Car Audio and Home Stereo, Feedback Loop Isolator, Car Stereo Ground Sound Suppressor, Reducer Alternator - Image 3](https://m.media-amazon.com/images/I/71EWxB-101L.jpg) ![InstallGear Ground Loop Noise Isolator, Amplifier Noise Filter for Car Audio and Home Stereo, Feedback Loop Isolator, Car Stereo Ground Sound Suppressor, Reducer Alternator - Image 4](https://m.media-amazon.com/images/I/81IbyEOzWtL.jpg) ![InstallGear Ground Loop Noise Isolator, Amplifier Noise Filter for Car Audio and Home Stereo, Feedback Loop Isolator, Car Stereo Ground Sound Suppressor, Reducer Alternator - Image 5](https://m.media-amazon.com/images/I/71WW9f0ywdL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is this unit self grounded?** A: This device is designed to break a ground loop when it occurs over the “signal ground” of a signal wire. The shielding from the male end of the cable is not connected to the shielding of the female end of the cable. It will only help if your buzzing was due to a ground loop over an unbalanced signal wire. **Q: Would this cancel the noise of engine on the speakers?** A: Got noise coming from your alternator or engine noise. Try a capacitor on your alternator output tied to your power line to ground. Here are some links for a capacitor and info to go with it. https://www.google.com/aclk?sa=L&ai=DChcSEwjb4pXD-oXmAhXRhlsKHceVASoYABAHGgJ5bQ&sig=AOD64_1S4G0-DN0dn2DMZvhGLCgkQIww9w&ctype=5&q=&ved=2ahUKEwio0YrD-oXmAhUKeKwKHTRlArcQ9aACegQIMhA4&adurl= http://www.capacitorguide.com/filter-capacitor/ **Q: como se instala?** A: I installed mine right next to the amp in the back floorboard of my truck. Isolator has 2 RCAs one each to your deck and amp. I installed mine backwards from the labeling because inputs to amp are female and RCAs from deck are male. Works great. **Q: Could I use it to convert an unbalanced 600 ohm line level load to a balanced load?** A: No. This is not that kind of transformer. You would need something like this: https://www.amazon.com/rolls-DB24-Stereo-Direct-Interface/dp/B001032GK8/ ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fixed the crackles and pops in my '96 Corvette -- cheap, well-built fix *by E***K on March 11, 2026* After swapping the factory stereo in my '96 Corvette for an aftermarket head unit, I got annoying crackles and pops through the speakers—classic ground loop issue.

Stuff like my AC on will produce a ringing sound, with stereo off completely, applying brakes will make a static pop, etc just frustrating issues to deal with. This was after I spent a good bit of time, and money to upgrade the sound system of the car all at once. I went from poor sounding music, to better sounding music ... with CONSTANT never ending static. I was hoping this product would help me, sadly it did not, it didn't make any noticeable improvement (it did make a noticeable difference) that being it changed the frequency of the sound of the static ... to a more annoying higher pitch ... so all in all I would say this product made the problem slightly worse by changing the pitch of the static. ## Frequently Bought Together - InstallGear Ground Loop Noise Isolator, Amplifier Noise Filter for Car Audio and Home Stereo, Feedback Loop Isolator, Car Stereo Noise Suppressor Reducer Alternator, Ground Loop Isolator - BESIGN Ground Loop Noise Isolator, Buzzing Noise Filter, Buzzing Noise Elimination for Car Audio and Home Stereo System with 3.5mm Audio Cable - BOSS Audio Systems Ground Loop Isolator B25N noise Filter for Car Audio Systems --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/56210531-installgear-ground-loop-noise-isolator-amplifier-noise-filter-for-car](https://www.desertcart.pl/products/56210531-installgear-ground-loop-noise-isolator-amplifier-noise-filter-for-car) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-25*
