  • Awesome!
I decided to give this a try since my Alpine MRP-1000 does not have an RJ45 port and I am so glad I did. This CT Sounds Bass Knob does exactly what it stated it would do. Upon it's arrival, I scratched my head trying to figure out where I would install this on my 07 Scion tC; and at first I was going to screw it to the underside of my dash, but no, I wanted it to look professional. After taking some measurements, I decided to cut the devices screw tabs off so that it would fit perfectly in the center console pocket. After modifications to the underbelly of the pocket, this little guy fit like a glove. Unfortunately, the knob protrudes beyond the closing point of the cover, so it has a 1/4" rise to it when closed. Which isn't a big deal for me. Plus, when I want to turn the device on/off, all I have to do is push the cover when it's closed. BAM! It will be open most of the time anyway. And the best thing about it's location is that while driving, since my right arm is always resting on the console, I have super easy access to adjust the output. I have noticed (as other reviews have mentioned) that there is indeed a cutoff point where it doesn't really have much of an impact. Again, that is no big deal for me as the ease of use saves me the hassle of taking my eyes off the road while driving just so I can navigate through my head units touch screen functionality. The included wiring diagram on the back of the package was perfect for an easy install. I did however order the exact colors of the wires needed (18AWG) so that I could solder at the unit and made a custom wire harness just for extra pizzazz. Used quick connect ends for the remote wires in the event I ever have to remove it and piggy backed directly off the head units power and ground. Too easy! Overall, I am very happy with this purchase and I highly recommend this CT Sounds Bass Knob! Looks awesome - sounds awesome! ... show more

  • Great functioning knob!
I purchased this knob for an Orion amp that I misplaced the remote for. The knob probably works better than the factory one. The led readout is a nice touch, and amp on/off control is nice. My only complaint with this knob is how ridiculously short the wiring is. Finding an install location that would allocate 4 wires, and 4 rca connections that close to the unit was difficult. Overall great product. ... show more

  • must have

  • Not Impressed. Great Idea Poorly Executed.
Would not buy again. Switched from a Skar Audio bass knob and will be switching back. The Skar Audio knob is metal and the know itself feels tight when turned. This one however feels plastic and cheap. The knob turns very easy, not tight like the other one. This may be a matter of personal taste though. Also the knob does not seem to be fully linear. The first half of the knobs range barely makes any audible difference while the second half of the knob makes a lot of difference. The Skar audio knob was completely linear across the knobs entire range. Biggest issue is the voltmeter, which is the whole reason I got this knob in the first place. It is off by almost 1V. My voltage will read 14.1v on my head unit, my multi-meter, and my cars ECU. But this will display anywhere from 13.1 to 13.5. Odd thing is I have it connected to the same line as the head unit. I assumed the head unit was wrong but after further testing everything reads the same except this bass knob. Complete waste of $30. Also have had issues where it gets stuck displaying "Off" or "On". or the voltmeter just wont turn on at all at times. I know I may have just received a defective unit being my first experience with CT Sounds I will stay away in the future. *Update* Voltmeter starting working normally again, still wrong but working. Worked for maybe a week and is now completely dead. This thing is garbage. Will be removing once the heat lets up... *Second Update* Voltmeter started working again and then stopped. It now will not turn off and displays random characters. Knob also came off. Easy fix, I know. But should not have to be fixing anything. Thing is garbage. Get a quality bass knob and voltmeter. Was a nice concept but they either use garbage components or employ terrible engineers. Avoid this garbage and save some money. ... show more

  • its just an amp gain.
..with that being said. lets start wit the good . 1- it works and it has a voltage gauge on it if you need it. 2- it works like you think it does. it just decreases/increases the gain control to the amp. that's all, no more no less. ok and on to the bad. the rca leads are about 2 inches. yes ,2 INCHES. that's so dang short for something like this. 6 inches is the norm for something of this type but they skipped on that part. 2- you have to set the guage with a very small screwdriver or it will be off. the voltage is adjustable on the unit but if you do not have a screwdriver with a Very fine point on it, you will not adjust it. it ONLY matters if you care about the voltage gauge on it. there is an on off button on the doohickey that's the actual gain knob. press it in and it send voltage to the remote wire on the amp. did i use that? nope, not needed for me But its helpful for ...somebody somewhere. so to make it short. there's a voltage guage on it that's adjustable and has no effect on anything other than the display on the unit ,short rca leads and a side screw for voltage adjustment that requires a VERY fine point screwdriver. even the pointy end of a wire tie wont fit it. over all i give it a 7-8 out of 10. i removed 2 stars for the short rca ( not that big of a deal BUT IS A big deal if you are mounting it where 2 panels meet inside the car. it makes it bulge out a bit. and for the adjustment screw. side note. the voltage adjustment is NOT for GAIN control. its ONLY TO MATCH THE VOLTAGE OF YOUR CA AND NOT FOR RCA VOLTAGE. just had to say that part. ... show more
