This has no hz control and seems backwards...dont buy this its total junk...

This bass knob is sweet. Easy to install. Makes a big difference in my system. The hearts knob cover came off but its nothing super plus won't fix.

This products works great especially for the price. It was really easy to install and is still working fine.

hey This volume control works great, I have it installed in my car for several months and have had excellent results, it is easy to install and use. 100% recommended it

Ruined my signal and made it all sloppy.. Rode on it for a week then took it out. When I took it out, I noticed a big increase in sharpness.

Great if you have a wide variety of musical (and talk radio) taste. Quick, on the fly adjustments. When John B. Wells starts speaking, bass must go.

Works fine as a gain knob, but the crossover doesn't really act as such. It acts like second gain knob. Save money and get a plain gain knob.

Well, this thing is a pretty neat idea. Easily change crossover settings from drivers seat as well as gain. However, i dont believe the settings on the dials are completly accurate. You may have to adjust some on the amp in order to open the range enough for this to take over. On the plus side, install was simple and took 20 mins. Once it's hooked, it does work. Best advice, dont look at the numbers on it while adjusting, use your ears. Overall, for 12 bucks, pretty cool add-on. BTW, get at LEAST a 3 foot rca to go with it, the rca's are its leash, and limit mounting location accordingly.
PROS: easy install, cool gadget, price,
Cons: not 100% accurate, may not last for years.

Perfect for in car use instead of trying to tune off the amp. Best money spent.

This is a great add-on device for anyone looking to improve subwoofer sound and have control as well.

This part is awesome - when it works. This is the only one I could find that not only adjusts the bass level/volume/output, but also allows you to adjust the hertz level so you can adjust based on what type of music you're listening to.

Unfortunately though, mine broke after less than one month of ownership. The unit started putting out a very loud hum to my amp/woofers when I had the hertz turned down. When I turned it up to 200, the buzz/hum went away.

I verified it was this unit by removing it from my system, and the noise went away.

Great product, great idea, but I don't have $17 a month to replace these all the time.

Hopefully my replacement unit will last longer than a month.

Works good easy install to anyone that needs a universal remote bass knob.

This remote is perfect for adjusting the frequencies and sub volume. I have been an audio engineer for many years and am quite fussy about sound. This unit is a GREAT value and gives you the control you need for all types of music to maximize the experience

This thing is great, very simple to install and overall very surprised because of the price that it's actually pretty well made.

This product Is great saves me all the crawling around in the trunk to adjust the levels on my amp which in a civic is quite hard to do. Install is as simple as possible just plug it in the RCA jacks btween your head unit and amp.

This item is for music lovers that wants simple installation of Bass Control. Even though basically simple to install and use, it has almost the same capability of other quality equalizers available on stock.

I installed this with one of the Amplifier that I use only for Bass whilst I use other equalizers for Mid and Tweeter. It is well marked as to which is input and output and can be screwed onto any parts of the car.

I highly recommend it to music lovers out there, who wants simple basic bass control with quality.

Product worked perfectly. I'm able to turn the bass up or down. Comes in very handy when switching from rock to hip hop.

it does what it needs to do the only bad thing is that the letters come off if you rub them when you turn it up or down. other then that its really nice.

For the price and function, great product.

I bought an Absolute ATV 910BT and it has bass control deficiency. This fixed it, big time. The adjustable cross over frequency is what really makes this controller shine. Not to mention you no longer have to rely on the amplifier's controller if it even has one. They can't screw you up by getting broken/stuck anymore either, set your amp once and use this to dial it back.

this is a def buy easy connection i have it in my show truck and i added a couple decibels to my system it is a good buy and fast shipping

Pros: For one , no one explained in reviews that this turns the bass totally off then you can crank it for your full bass. That is a big A+ for car audio! Most cheap bass knobs from the amp dont do that.
It looks great mounted and the frequency knob works great also. Im running a dpx11551 1550rms amp.

Cons: None!

Thank you Sonic Electronix

This remote is great to control a bass amp. It works perfectly with any amp.

The BC-1 is still working like brand new. It allows me to change my gain and frequency for each and every track that I play on my stereo. I would definitely buy this product again and if you don't have a built in base remote for your amp i would suggest this.

I didn't initially think this unit would work as well as it claims to but it indeed does! Would use it again if I had to!

The BC-1 did exactly what it was supposed to do. It worked perfectly and easily and even looked good.

Mine was not the same as the one in the picture. Instead the RCA's on the back were wires sticking out the back of it instead of being mounted in it. Wasn't a big deal, must be a different model. But now the good side. I love this bass knob. It had super fast shipping. I ordered it on a Sunday and it got to me on Friday. It also increased the quality of my bass and I dont have to flip through screen of menus finding the right one.

Great way to control the subwoofer. Reasonable size and easy to install.

Great style!!

I love this bass knob! It has worked perfect for me and I would highly recommend it.

GREAT BASS KNOB... I HOOKED IT UP TO MY SET UP OF A "15 SOUNDSTREAM, 3 "10 JL'S (3 MUSKETEERS) AND A 1200W POWERBASS AMP. THE BEST THING IS BEING ABLE TO CNTRL THE FREQ AND THE GAIN. THATS REALLY WHAT SETS THIS KNOB APART FROM ALL THE OTHERS. AND IT MAKES A HUGE DIFFERENCE...

This product is great as a bass knob, but I mostly bought it for the crossover. The crossover is awful, it barely removes midrange and high range frequencies, no matter what you set it at. But overall, it makes for a good bass knob.
