  • Good quality Converter

  • Ditch Audio Control
Size: 2-Channel with xBOOST
My audio control 6i loc unit started giving me problems after 1 year. The unit started giving me random static noise on all channels. I double check out all connection's they were fine. I finally decided to ditch the loc and get me a new nvx. This unit sounds amazing and fix my problem. Well worth the price and converts clean signal for ur car audio. I'm a believer for this brand for live. A++ ... show more

  • Great buy
Size: 2-Channel with xBOOST
So, here is what I have found. The unit works great. I am passing an oem amp bass channel output for my 2015 VW golf (fender system). As advertised the unit restores the bass when the oem drops off, but I noticed that there is a delay when the bass comes in at the set high volume. Nothing too crazy but it is noticable. same thing when turning the volume down it will take a bit for the bass to drop off to regular level. So, for a little bit the bass will be louder than the speakers. It's not a deal breaker and I also have an lc2i in another stock system and it does about the same thing. At least here the value proposition is better. Nvx gives you the bass knob and it's almost half the price of the lc2i. Worth mentioning is that you can set the rca inputs up to 10 volts if your amp takes that high voltage. Overall, I am happy with the unit. ... show more

  • Perfect for adding aftermarket amps and woofers to a factory head unit.
Size: 2-Channel with xBOOST
Worked great, easy to install. I wish there were more instructions or videos on how to set it up for optimal performance but I figured it out after a little bit of tinkering. Wiring and setup were easy, for the most part. The remote sensing feature is great but it has some drawbacks. If you have a smart key system that for some reason activates the stereo like a 2023 Kia Forte this little guy will turn on and also power on your amps. This had me worried that the amps would drain the battery but it doesn't because the car times out and shuts the radio off automatically. There are other things that annoy me about that but it's a fault of the car and not the converter itself. You can also wire it up differently to turn on other ways so it's basically a non-issue. Highly recommended if you want to keep your factory radio and add subs. ... show more

  • Quality control not very good
Size: 2-Channel PRO with xBOOST
I received and the switches were hidden behind the front panel. Like the circuit board underneath was not aligned with the case so you could not really even get a tiny screwdriver in there to move the switches. I finally did but it was a pain. Then when I moved the ground isolation switch it stopped output to the RCA cables...That is not supposed to happen. It should output signal to the RCAs no matter which selection you have the ground isolation on. I returned maybe I just got a bad one because NVX is usually pretty good. Installed a LCi2 audio control with the same features and it worked perfectly so this was indeed a bad unit. ... show more

  • Lower Price than competitors, but with its caveats!
Size: 2-Channel PRO with xBOOST
Compared to the LC2i Pro, this product comes at nearly half of the price! So here's the pros and cons with this option. PROS: - The bass roll off feature works pretty great! It takes a minute to dial it in just right, but once you do, the converter continues boosting your SUB signal through your whole volume range, making your sub sound consistent at 10% volume all the way to 100%. - Included bass knob, with options for double sided tape and screw mount bracket. - The quick disconnects make upgrades, reorganization and replacements very easy and convenient. CONS: - The bass roll off feature is based on the output of mids/highs. It detects that the volume keeps climbing and makes sure that the bass follows. Only problem is that the algorithm used for this takes a second to kick in. [For example]: Volume is at 15, bass is at 15. Volume is now at 30, stays at 15 for a 2-3 seconds, and then climbs (delay). (Or vice versa) Volume is at 30, bass is at 30. (You turn down the radio to talk to someone). Volume is now 10, but the bass remains at 30 for a few seconds before also matching the radio to 10. (Perhaps this is an issue that more premium products could improve on). - The super special telephone cable broke (An uncommon variant because both ends are NOT the same, making it hard to find a replacement). This cable is used to connect the bass knob. I had to contact the seller. The seller declined to just send me a replacement and I had to get in contact with the manufacturer. Still waiting for a resolution. - This is my second unit. The first one, went up in smoke due to a defect. They replaced it free of charge, but still... In other words, consider the cons before you buy because those extra dollars can result in a more pleasant, and reliable product. I'm already working on purchasing the competitors offering. ... show more
