Audiotek AT-AP100 1/2 Din Car Audio Digital Bass Processor & Sound Restoration, Crossover for Car Subwoofer Tuners w/Bass Knob Input 15V RMS and Maximum Output 13.5V Peak

1st Off... this product will not make your sub louder, instead it will restore the volume and quality of sub bass between 27hz and 65hz with the sweep knob. “Restore” meaning if your sub isn’t good at playing low frequencies between 27hz and 65hz this device will fix it and and you’ll be able to hear those frequencies in your music again with great quality.Ease of product: 10/10 So easy to install IF YOU ALREADY HAVE AN AMP INSTALLED ( Because all you do is connect together wires from This product to REM, PWR, GROUND, And RCA To the amp, and done 3 minutes MAX )Quality: 8/10 Feels Nice Made Of Metal. Light weight, and sleek. Comes with hardware, and very understandable user manual.Function 1: 10/10 Cleaned Up Muddy Sub Bass with the 35 Hz Subsonic Filter ( it Got rid of harmful frequencies for ears and sub its self that can’t be heard because they’re too low anyways, and gave clarity and quality to sub bass)Function 2: 10/10 made my sub quality incredible because it puts out 10 Volts, now I’m reaching the full potential of my DVC 8 ohm 10” Kicker sub.SIDE NOTE: I was able to hear my sub bass by switching the phase of the sub ( putting the positive terminal on the negative input on the amp, and the negative terminal on the positive Input on the amp ) just try it if you’re having trouble hearing your sub.Anyways... overall 9/10 product, actually wait this thing is only 30$??? 10/10!!!

AudioControl Epicenter Concert Series stopped working and got this Audiotek to replace it and wow...can't believe it does so well at its given price. If you're not sure if this is a good product or not, rest assured it works great.

I bought it for a costumers never got the chance to review it but he as no complaints so I guess it's perfect for him could send one let i really review and send back for now

Great products and customer service. Thank you

Worked good for about 2 minutes made sure had song playing with bass tones taken out I know what this does and how to use it everything was properly installed and set properly but it burnt up in a matter of minutes horrible smelling smoke filled the trunkInstalled different brand device same exact way same cables and it worked flawlessly for hours haven't had an issue yet.

Not the best but it gets the job done.

Bought one, was easy to install sounds amazing made my small 300 watt kicker amp with 2 12" kenwood sound like I had a 1000 watt amp with 2 15" was very happy I bought another so I have two one in each vehicle I recommend it if your trying to make your system sound clean for a low budget

If you wire it right it will change your lifeI was looking for deeper base range and stronger beat and I found it and then some!
