Massive Audio Hi-Low - Car Audio High Level Speaker Signal to Low Level RCA Converter, High to Low Level Signal

The Massive Audio Hi-Low Converter works great. Used it to add subwoofers to my sons Hyundai Elantra. It enabled him to keep his factory head unit and use the subs. Wiring was simple, good instructions and it’s a sturdy little unit. The housing is made of metal and the harness is able to be disconnected so wiring to your factory harness is easier. The converter is small enough that it can be easily tucked behind the stereo. There are also no controls to fiddle with. It’s all adjusted inside automatically. Overall I’m very pleased with the quality and operation of it and I wouldn’t hesitate to buy another if needed.

Easy to wire and the remote out saved me. I couldn't find a keyed ignition 12 volt out coming from stock audi Navigation RSN so I was going to run a new wire to the fuse block but luckily the Massive Hi to low converter has an auto sense music feature that sends a remote to the amp. Thanks Massive.

These are NOT line output converters. These are simply adapters to go from speaker wire to male RCA. I am using these to bring a high-level input signal from speaker leads to my Massive Audio Blade BP800.4 RCA inputs thereby activating the signal sense automatic turn on feature of these amplifiers. These are good quality copper wire and less expensive than other brands. Plus, you get two, so enough to adapt 4 channels. RCA terminals fit nice and tight. Here is the problem; On each channel, one bare wire is marked with a stripe designating negative polarity. Well for one of the channels this is backwards and you need to check it with a multi-meter so you don't hook it up backwards. Otherwise it would get 5 stars.

Used to connect speaker outs to from the stock stereo on a Victory Vision to a Kenwood 4 channel amp and Polk Audio speakers. Worked better than expected. Upgraded stereo "SCREEEEAAAAMSSSS!! Loud as HE__!!

I purchased this in September 2020, it worked great for 3 years, and then it quit giving me the right volume, eventually not working at all. Beware if you buy this you should get at least 3 years of operation and then it might fail, it could fail sooner than that.

Was very hard to turn, to Increase or decrease the bass. Other than that, it worked as it was It should

These cables are less than half the price of the JL Audio cables and work just great. I used them to connect the factory stereo in my 2019 Sonata to JL Audio RD900/5 amp.

Worked as it should , quick shipping , easy install and am glad I can adjust the subwoofer bass separate from everything else. I absolutely love the sound massive audio speakers & subwoofers produce!
