Description

Keep the stock look while enjoying a sound that is anything but stock with the Q-LOC5 Active 5-Channel Line Out Converter. The Q-LOC5 safely integrates modern high-output head units with SoundQubed amplifiers. Because a line out convertor allows you to dial in proper source voltage, you can prevent a clipping signal from the head unit. A high to low output converter also lets you tap into a powered speaker signal to add a subwoofer to your factory system. The active Q-LOC5 can switch from 5-channel to a 2-channel mode. In 5-channel mode, you’ll have separate signal controls for to 2 front speakers, 2 rear speakers, and a sub stage. What is a line converter for car audio? Line out convertors (LOCs) are an essential linkage in a car audio system. A powered line output converter gives you an extra control point in your system design, resulting in a clean signal at the proper voltage. LOCs are great for use with aftermarket processors and amplifiers because you don’t have to rely on replacing the head unit or infotainment interface to get a good signal. The high-level output signal going to your speakers from your amplifier is internally amplified for your stock speakers. This signal is too high for your monoblock and multiple channel amplifiers to boost without introducing unnecessary gain to the signal. LOCs can also include other features such as signal sense 12 volt turn on or high power outputs. The Q-LOC5 is a line output converter car audio beginners can use for adding a sub to a factory system. When tapping into a speaker wire, you can use an inline output converter for amp signals that are dialed to the correct level. Many new vehicles have a big fancy touch screen that controls everything. Replacing that computer and interface isn’t always worth the time and money. Because it’s so integrated, removing an infotainment interface can cause other problems with steering wheel audio controls and other functions. OEM integration in this situation can be a dicey situation. A line out convertor reduces the high-level output from your head unit to a friendly input level for your amp. Amplifiers aren’t smart. Whatever voltage comes into the circuitry is amplified in the same manner – even if it’s too high. High-level input voltage is amplified, and the output stage is driven to clipping. The Q-LOC5 is a signal step down with adjustable output. The Q-LOC5 can send output to 1 channel for front speakers, a second channel for rear speakers. When you're ready to add a subwoofer, you'll have an additional option to switch to 5-channel mode. Each channel has a dedicated clipping indicator, so you know you're sending clean signal to your amp by adjusting the gain screws until the clipping LED is off. Secure mounting tabs allow for discrete installation wherever you need to mount the Q-LOC5. Set-screw terminals allow you to tap into a speaker wire, or factory head unit. Standard RCA connections for each channel. Compact design with secure mounting tabs.

When tapping into a speaker wire, you can use an inline output converter for amp signals that are dialed to the correct level. Some head units have preamp outputs, but most do not. If your head unit has RCA outputs, you probably don’t need a line out convertor. How To Install Your Powered Line Out Converter Integrating car audio gear with new vehicles can be complicated. For basic upgrades to your car stereo line out converter installation is an easy way to tap into your speaker signal. Installing a LOC will add a few minutes to your install. If your head unit does not have low-level RCA outputs, it will be time well spent. Run power wire from your battery/fusebox to your LOC on the same side of the car as your power wire. If you’ve taken your headunit out of your dash, run a remote wire from here along the same side of the car to the remote in on your LOC. If you’re installing the LOC in your trunk or backseat and running speaker wire back to the front of the cabin for your door and dash speakers, run them along the opposite side of the cabin. Failure to do so can increase interference and a hum to your signal path.

  • Insane value
For 60 dollars absolute steal. Nothing else on the market was even close to this price. Works perfectly and even has lights to tell you when the input audio is clipping which is perfect for stock headunits where at max volume it will clip. Really easy to setup but I did buy molex connector terminals to put on the end of the wires before inserting helps with fraying and stability when installing them so it won’t break in the future ... show more

  • It is Great for the Money
This LOC will take 4 channels off of a factory system and convert the signal to usable output voltage for those 4 channels while adding a subwoofer channel. There is nothing else out there that I could find that would do this for the money. I am sure that there are units out there that would sound slightly cleaner, but not by a considerable margin. We are talking diminishing returns here. The main issue is working around your factory system's built in EQ/ Bass management system. Unless you are spending 3X as much you will not get that, and even then, that is just for the bass management. To be able to cancel out the EQ completely/ tune to your desired levels you'll need a DSP. So, name your price there. I bought an $18 LOC from DS18 and it was trash. I am not saying everything from DS18 is trash, I am just saying you get what you pay for. You can get bare wires in there, but I would not use anything over 18 gauge, and be sure that both the wires and the unit are mounted securely and not bouncing around with the car. They will probably fall out eventually. I am satisfied with this purchase. ... show more

  • Two things to absolutely know before you install:
1. You need to buy some male Molex pins for the bare wiring are going to be inserting into the LOC and tightening down, or some wiring ferrules. The reason for this is twofold. First, you are not relying on the screws tightening down on bare wires, and you get a more secure connection. Second, the part of the Molex pins adds rigidity to the wiring and will not bend right where the wires go in. Super easy for these small gauge wires to break off from bending. The Molex connectors will allow you to install the side with the pins to go into the LOC, and then when you get it in place you just connect them. It's very difficult to be doing this with bare wires in some tight place. 2. You need to figure out if you have a 12v+ accessory-on power wire, which will go into the 'Remote In' location on the LOC. If you don't have this switched power wire, you will get no sound, you must have one. If you don't, you need to tap into one going into the head unit. ... show more

  • It works great
I dont know what everyone is talking with screws coming loose. But maybe I was different as I didn't try to install it in place. I hooked everything up before putting it in my car, and those screws are tightened down and don't move. I could see where installing it in place could create that fiasco. But I hooked up a wire harness to it in bed and its solid. Small enough to jam somewhere into my dash, and works as it should. Also I don't have my accessory wire (Remote in) hooked to anything, it auto starts up and shuts down with the car so I'm not killing my battery. ... show more

  • Dont do it.
Very very disappointed in this product. After spending hours running wires and installing my equipment 2 of the 6 rca outputs did not work at all and the others had crackling noise if touched and noise present in the signal through the amplifier. After trying 3 sets of rca cables i discovered this unit to be the culprit. I did some research and was able to replace it with a competitor's line converter AND the radio T-harness from PAC audio for less than i paid for this junk. Maybe it was just my unit maybe not but i wouldn't risk it. ... show more

  • Better Options Available
Product was not working well with my installation. May have been just an issue with this unit but I purchased a better quality LOC and had none of the same issues. I received very bad static noise with this unit unless the gain was turned all the way up, which in return brought it's own static level. Would constantly have clipping on all channels, though I tuned both LOC and amplifier to correct levels with a multimeter. Was a fan of the compact size which made easier for installation fitment. Also, had no issues with the terminals securing the wires. ... show more

  • Works great, amazing sound quality for the price
Haven't run into a single issue, works perfectly. Used to bypass the factory amp in my 14 Mazda 3. Ran to 2 amps and it sounds fantastic. Easy to set up and simple to tune. Yes it needs an accessory in, it doesn't have auto detection for remote, but it worked for what i needed
