Perfect

worked perfectly, no problems at all, but if you're having gain problems which I did at first just switch your input and output.. very satisfied

This Thing Rocks

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.

Universal Bass Remote

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.

Great device

After hooking up the remote I was amazed at the control I had over the bass. Turned all the way down you had no bass at all. Turn the knob up slowly and the bass would start to come in. Depending on how your gain and cross over is set you can go from no bass to window rattling chest pounding bass. Pretty cool.

GREAT Product! Great Value!

This is a truly excellent product! I purchased and installed it after I realized that an EQ I was using was actually robbing my amplifier of power (I must admit, though, that I bought this EQ used on Ebay). I have this knob inline for my subwoofer amp.
This volume knob has a solid feel and is tight in the rotary turn. To me, this gives it more control so that you don't overshoot your desired level. The actual knob is metal, so there is substance to it's feel and doesn't seem cheaply made. The size is not too big and not too small, so it is easily installed in many locations. Finally, this module passes a clean and strong signal through to the amplifier.

Pros:
Metal knob
Tight-turn control
Good size
Passes through full undistorted signal (tested using SMD DD-1)

Con:
Slightly loose female RCA connections (Can be easily fixed by pinching ground ring of male RCA's or taping the connections).

I HIGHLY recommend this product!

This Volume knob is inline between the sub output of a JVC touchscreen unit (at full undistorted volume) and my Sony XM-GS100 Mono amp.

Works great!!

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

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.

definately worth a try

Hello every one, about a month or so ago, I purchased this schoche bass controller, and if was ,100 percent worth it. The installation was a snap, I pulled put my headunit, drilled a hole in the attached shelf below to run the wires through, then screwed it in. Depending on your audio set up, youll need a lengh of red and white audio cable(name slipped my mind), connect said audio cable to the output on the deck, then into the remote, then plug the signal cavle that were going to your amp, and your ready to rock! I use these to control two 12" rockford fosgste subs, and boy does it make a world of difference, from a subtle drum kick, to the booming bass in electronic music, it can help you tune your music, just right! Thanks for your time reading, and I hope this helped you make up your mind, thanks!

Great Product

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.

A great gain controller

This is a much nicer unit than I thought it would be. The knob is very fluid and has a nice "middle" notch in it. It is also pretty accurate. The unit is small enough to install just about anywhere.

I do wish that it came apart easier, so that you could install it behind panels.

For the price, I will order it again if needed for another system.

Im not really sure about durability because I have only had it a short while. SE should probably do away with the "Durability" block anyways.

Does the job

Not the nicest or the most accurate remote but if you can't find one specific to your amp, this one will definitely do the trick. Heads up though, the mounting screws that came with mine had a head way to large for the mounting holes so you may need to get your own screws. All in all I'm satisfied with it and would recommend to anyone that needs a universal bass remote.

Surprised

I recently installed this universal bass remote on my system. My amp came with a bass remote which only allowed you a 0 to 12 db bass increase. This worked fine until I snapped the phone connector off of the wire. I tried to attach a new connector to the wire but it never worked quite right. So I decided to go with this set up. The install was very easy, out to in, in to out. After I installed it I wanted to readjust the gain on my sub amp. I had the EFX turned all the way down so when I started to raise the gain on the sub amp, nothing would happen to the bass. I mean there was no bass at all. Turn the gain all the up and nothing, nada, zilch. With the old bass remote even when it was turned all the way down you would still get a fair amount of bass depending on the settings I had. At first I thought I broke something, then I turned the bass remote knob up and started to get bass. What I ended up doing was setting my gain at the mid point then just adjusted the bass level with the new bass remote. I have much more control of the bass than before. You can go from 0 db which would be no bass at all then with a turn of the knob you will get all the bass you can handle. Turn it to high and things start to rattle. That would be a no no. This thing gives you nice even precise bass control.

Great for controlling subwoofer levels

I installed this in my girlfriend's car so she could easily adjust the bass without 'boosting' anything. It does exactly what it should without being flashy. My only complaint is the knob, it's a bit large. Some smaller knobs will fit, just find ones with the same size/shape mounting hole.

Perfect bass knob for any set up

Purchased for my 2007 Tundra. Kenwood DNX in-dash DVD, Nav, Sat. Radio. Head unit has these controls already, but having a knob to adjust on the fly between songs is WAY better than having to scroll through menu's to adjust the bass. Listening to music is actually more enjoyable since I dont suffer through the one or 2 songs with too much or not enough bass since I dont feel like messing with the settings on the head unit.
Works with ANY amplifier set up so long as your using low-level RCA inputs. I also removed the product from the slightly bulky case and was able to fit it inside the dash behind a blank factory cover.

The gain control could be a little more responsive. Between zero and half turn the column seems the same. Between half and full volumn sounds the same. As if it only has 2 settings instead of a gain.

Buy it now!

I've used a lot of different knobs from all different brands and this is definitely a quality knob. It doesn't feel great because it is plastic other than the thumb wheel but it has what's most important...... linearity, it has a nearly perfect response through out its range and I've used much more expensive knobs that weren't nearly as linear. Great bang for your buck and in my opinion it's a must-have.

The Best RCA Remote

I'm glad I read all the reviews of the different rca line level remotes that ultimately lead me to buy this one. It's the best sub remote I've ever had. The dial is progressive and easy to dose, with a very solid feel and a midway notch that comes in very handy. As mentioned in other reviews, turning the dial has a nice resistance to it, exactly what you'd want.
I highly recommend this to anyone who wants to control the volume of an rca channel on the fly, whether it be your car's sub or a desktop computer speaker setup.
Can't beat the deal from Sonic either!
