This Thing Rocks

September 11, 2013

Okay, so EVERYONE needs one of these if you have a basic subwoofer. It allows for such a large amount of versatility to play around with how loud that signal is going into your amp on the fly adjustments. So COOL. Plus, super cheap from Sonic Electronix. Nothing but good things to say about this.

So handy to be able to change the bass level easily instead of trying to peck through the decks menu for each song. I think this is a must if you listen to different types of music and have a sub in the backseat/trunk.

This subwoofer level control has not failed me since i purchased it and does exactly what i needed it to do. I have an amp which did not come with the OEM level control when i bought it. This was an excellent replacement.

Universal Bass Remote

April 29, 2014

Remote works like a charm.

The quality is pretty good but not the best. I was going to mount it with double sided tape but the screws help keep the two halves of the case together and would mean less movement. I used a ziptie around the body and through the two screw holes because I can access the space behind its mounting point. The knob has a bit of a notch to catch it in the middle of its range. Unfortunately, it's a little right of center. Doesn't bother me any, but some people may not be able to handle it. The knob has a fair bit of resistance that is great for dialing in. It keeps you from just cranking it on accident if you hit a bump while adjusting.

Installation is easy but you will have to make a hole big enough to get the RCA connector and the 3 other wires next to it (not a big deal). Plug in the RCA's and that's it.

Turn up the sub output all the way or you will be attenuating the signal twice. I have heard no extra noise or diminished output when it is turned all the way up.

Great product, cheap price, fair quality, perfect usability.

Worked great, easy to install. Only complaint is that the screws that came with it didn't fit so I had to buy new ones.

Works great!!

August 16, 2013

I've had it installed in my 2013 WRX for a few months now and it works great. I mainly listen to music from my iPhone and I have 40 gigs of stuff anywhere from 1950s to modern music. Anything prior to the 90's has almost no bass, so I have to crank up the bass for that stuff and turn it down for the newer stuff. I got tired of going through menus on the stereo to do it. This allows for quick adjustments without taking your eyes off the road. Love it!!

Gain Controller

February 19, 2013

Works great for a amplifier that doesnt have a remote gain control. I place this under my passenger seat, under my mazda 3 that has bose, since the bose connections allowed me to tap into the wires to use the LOC, makes it very discrete and hidden well. Keep at max however. Its a good tool to turn the bass off if someone doesnt enjoy that type of music style. I broke it in half, so electrical tape makes the finish looks sleek.

this is a standard bass knob but one thing i really like about it is that has a center point that it catches on so you know where the plus of minus 0 db is for a nice flat response. i would recommend this product

I would recommend this product to anyone looking for a good universal bass knob.

Pros: Cheap, good quality, knob feels good
Cons: Wish it lit up at night, not much difference between half way up and all the way up

July 23, 2012

Just got this controller hooked up in my car and it exceeded my expectations. I thought i would have to settle for a little interference being how you hook up this controller through your RCA's but there was none whatsoever. Do know that this only adjusts the GAIN on the amplifier and NOT the bass boost. Also, this controller is not a complete override of the gain knob on your amp. Ex.: the controller will completely turn your head unit's RCA output off so your subs/speakers will be off, but if the gain knob is set to a low setting on your amp, the volume will stop rising after the controller gets to about half setting. So just crank the gain and the bass boost on your amp so your controller is most effective and has a full volume range from min to max. Oh and by the way, the picture of the controller makes it look a lot bigger than it actually is. Maybe not the smallest bass controller, but it's going to fit pretty much anywhere you want to put it. (even fits in the storage gap in my stereo's mounting kit) Overall, good design, very easy to install, and great value.

I have a stock head unit. My amplifier and subwoofers are powered by speaker level inputs. Will this work by plugging into my RCA inputs on the amplifier?
Will R on Feb 20, 2015
Best Answer: Yes, the bass knob has an input and an output. The input- run an RCA from the input of your headunit into the input of the bass knob. So the rcas that normally run directly into your amp will instead run into the input of your bass knob. Output-an RCA will plug into your output of your bass knob and then run into your amp. The knob pretty much acts as a bipass through your amp and allows you to control the bass. But I'm sure you already knew that! Good luck and I hope that helped

in the picture I see 2 sets of inputs does this mean I have to but a 1 foot rca cord to hook it to my radio and have it hooked to the rcas going to my amp hooked to the other 2?
A shopper on Jan 23, 2015
Best Answer: Yes, you're going to need a short cable to connect it to the back of the head unit, and then you can just use the RCA cable going to the amp.

would this work for my audio control epicenter as a replacement knob?
matt s on Nov 18, 2014
Best Answer: Yes, it would work to control power input to the Epicenter. If the Epicenter control knob controls the signal input/output, it should work the same. If the Epicenter controls something different, like frequency level, then this knob wold not work the same.

Why not spend $6 more for a replacement Epicenter control knob?
