This is the best value on 4awg & 1/0 Tinned OFC wire in the universe. It’ll make your skAr amplifier and power bass subs sound like an old school Linear Power amp pushing a Resonix GUS subwoofer. In fact, I showed my grandma the deal on this wire and she wants some to power the system in her 71 Plymouth Duster. Great wire at a great price point!

Excellent! Sticks better than the rest

Shipping was fairly prompt. The extra thick panels I bought were really good and easy to work with. Highly recommended.

Does the job great! Absorbs the sound amazingly, but it is a one time only thing. If you stick it on and need to re-adjust, it will not be clean

The original Conductor was good, but the build quality left a lot to be desired. The Conductor Pro is a premium piece of hardware. If you've invested heavily in a Helix DSP the Conductor Pro is a no brainer. It’s a night-and-day difference in tactile quality

Highly recommend Resonix Guardian for door with midbass. It’s and excellent sound absorber. The adhesive is extremely sticky so be careful not to touch it, you can also mist it with a bit of water to give a few more seconds in order to fit.

Great roller, works well with the cld squares and the other rounded end works for pressing down in those annoying divots in the metal

You cant go wrong with Helix amplifiers as well as the support of Resonix staff

An amazing amp in a compact, class D format. Buying from ResoNix ensures that I will have support and confidence any issues will be managed well and that gives me piece of mind

Does exactly what it’s meant to do. In particular, the adhesive is great and makes it versatile and super easy to apply.

Great stuff. . . very high quality!

Shipping was quick, well packaged. I've used Resonix in a few of my cars over the years and I really like it. It just does what it is supposed to.

I installed ResoNix LITE in the doors of my 26 Bronco - I couldn't be any happier with the result. It made more of a difference even than I'd hoped. Well worth the effort.

I used this for my wheel wells, following Resonix's wheel well guide, and it worked great. I hear less sound from my front wheels and the product was very easy to cut and apply.

I’ve used a lot of sound treatment products over the years, but after fully treating my Lexus RX450h+ with ResoNix materials, I can confidently say this is on another level from typical automotive sound deadening products. My goal was not just “less noise. ” I wanted a true luxury-level NVH experience — reduced road noise, lower vibration, improved audio clarity, and a calmer overall cabin environment comparable to ultra-luxury vehicles. ResoNix delivered exactly that. My vehicle received extensive treatment including: CLD treatment throughout doors, hatch, wheel wells, firewall, pillars, floor, and cargo areas Guardian barrier treatment in doors and other key locations Fiber Mat absorption layers throughout the cabin Decoupling treatment on touching panels and trim interfaces Tesa wrapping and seam treatment for vibration/rattle elimination The difference after installation was dramatic. The biggest improvement was road noise reduction. After heavily treating the wheel wells and body structure, tire noise on the highway dropped to the point where wind noise became the dominant sound source. On smoother asphalt, the cabin became eerily quiet, especially in EV mode. What impressed me most was how “solid” the vehicle now feels. Doors close with a heavier, more refined sound. The cabin feels more isolated and composed at speed. At 70–75 mph, the vehicle feels significantly slower than it actually is because of how calm the interior became. One thing that really proved how significant the changes were happened when my RX was at Lexus for an oil change and I received a Lexus loaner vehicle. Same model and year. Before doing the ResoNix treatment, I probably would have thought the loaner felt perfectly quiet and refined. Instead, the difference was immediately obvious. The loaner suddenly sounded hollow, noisier over rough pavement, and much less composed. I could hear more tire noise, more panel resonance, and more general background harshness that I nor...

Definitely worth the money. Packaged nicely and arrived in a timely manner. There is a very noticeable difference in the sound when doors are closed. Lightweight as well.

These are by far the best cables I have used! Not just from a sound quality standpoint, but from a low cost customizable standpoint as well. Easy to cut to length to give just the correct amount of cable with no slack. Comes with cutting tool for a super easy diy set of custom cables. Thanks guys! Bravo!

This tape does a good job of quietting the rattles that can come from loose wires/plugs between panels.

This stuff is thicker than you think. Its great quality, adheres well, and is pliable. I ran into an issue because the design of 350z door cards is terrible and the door panel cuts down to right in front of the speaker halfway through and this foam couldn't compress down to nothing, but thats not their fault. Would definitely purchase again next time I need speaker rings.

This stuff is absolutly game changing!! I am obsessed with sound deadening now. I live in canada and i was just fixing a water leak against the firewall in my 05 civic. Unfortunatly required the whole dash,crashbar, hvac box,and blower box to come out to fix properly when my coworker was telling me to throw some sound deadening on the firewall befor putting back together. He recommended resonix saying it makes the rest of the stuff on market like toys. He knows when i take on a task i love to use the best of the best stuff known to mankind and will splurge at any cost. I spent countless hours installing MAX CLD and the Fiber mat over top of it. wile it took a wile to get everything to fit and put back together its finaly back. And i cant tell how weird it feels in my car. Its deffinightly takes some getting used to. I never really look at my RPM guage when i shifted because i just listened to the motor and shifted accordingly. But now its so quiet that my shifts are significantly sloppier. Resonix is truly far superior than anything i have delt with. After completing it i wanted to do more so i just bought more to do my floor and maybe a bit extra for now. My $2,500CAD base model civic that i bought years ago now has over 2,000 worth of sound deadening in it and will continue to rise untill the car is complete.
