it was recommended in sonic electronix you tube video. I want to retain my factory head unit but it doesn't have rca's (low level inputs) to connect to my new amplifier.

Can I use this on my 2016 RAM 1500??, I want to install 4 channel amp. for my new aftermarket speakers and mono amp. for my subwoofers.

I went to a local Fry's electronics store to get a quote for the system installation, but they told me that is impossible to connect amplifiers on the RAM trucks, I don't know way they say that, I just want to make sure if this line output converter will work on my RAM

Will this support a 5 channel amp? I'm looking to bridge 4 channels for the 2 front speaker and add a sub for the fifth channel.
rob h on Jun 5, 2016
Best Answer: Yes! This is a 4 channel Hi-Llo converter. By using a "Y" adapter you can split either the front, or rear signals before the amp and effectively end up with 3 stereo outs = 6 output signals etc..

I viewed the sonic video on this converter in which it is installed on a 2014 Honda Accord. I have 2015 Honda Accord with premium audio, which has balanced outputs. Is a product like this necessary to connect DSP to Amp and run active? How would you hook up the sub using the NVX?
Larry R on Sep 9, 2015
Best Answer: Hi Larry, i installed on my 2011 elantra i had to use hi pass filter on my amp for the door speakers because it didnt filter out the low frequencies and my speakers couldnt handle it. As for the sub run your amp on low pass you could put a equalizer before your amps from the line out. But mines clear just tuned from headunit then the amp

i have a bluetooth audio unit and to make this question simple the unit has connections for two speakers: I have two 4ohm 4" speakers connected to four wires, i.e. positive & negative per speaker and there are no rca connectors or connections for additional speakers on this audio unit. I also have a 400 watt amplifier with 4 channel rca inputs and speaker connections for four speakers. Can I use this LOC by splicing the LOC into the four speaker wires coming out of the bluetooth audio unit so that I end up with music out of the four speakers not yet purchased plus the existing two 4" speakers? If you haven't guessed this is for a motorcycle which has a factory bluetooth unit with built-in amp. Not adequate for highway speeds where wind drowns out the sound even if the sound is cranked up to highest level.
Anthony G on Apr 28, 2016
Best Answer: Personally I see nothing wrong with that solution. However, I'm going to assume that the converter will act like any other speaker (4ohm) in that it may drop your ohms down to 2ohms to the unit you are driving from. Just be aware of that potentially happening.

Also, I found that the converter picted up a tiny bit of alternator noise. For me it was a bit much. I had to use a noise killer in line with the inverter. Hope this helps.

This product says 600 watt maximum input, does that mean I can not use it with the Polk Audio 800.4?
A shopper on Jan 26, 2016
Best Answer: Hello,

The amplifier has absolutely nothing to do with that figure. "Input" literally means the signal being sent (i.e. Input) to the LOC from the headunit or OEM amplifier. Your amplifier doesn't and can't send power to the LOC...if it did, that would be very very bad =] .

To make things more clear, if your vehicle is equipped with a factory amplified system or you don't know, then go with this product. If you know it doesn't, then the NVX XFLOC4 will suffice.
