Taramps Universal Bass knob Control Car Bass Controller Volume Regulator Knob Amplifier RCA Audio ON/Off for Amp, Durable, Volume Remote, Black, Small, Adjuster

Does it's job well.

Installed to control sub Pre-amp level. Good feel when making adjustments. Was Easy to install and works perfectly to dial in signal strength.

flush mounted in my center console where the 3.5mm aux jack used to be.

So I got this in the mail and was very impressed by how it was made well built has a input and output on the back of it ,input goes to your radio and the output goes to your amp I found you can also just put the output straight to your amp if you have a adapter that plugs into it the amp that's what I like the most about it. The thing that I didn't like was that it was a misrepresentation it said that it had a on and off switch but it doesn't it only has a low in a high besides that that's why I only gave it four stars but all in all it is a good product just a little bit too big that's all but I can handle that.

Metal construction, knob feels absolutely phenomenal. A little bulky, but i don’t mind for how well the knob feels and works.

Works great

Works good like it should and being it’s rca hook up it gives clear bass the only thing is I have a different amp and it has a bass knob so this one works but it’s not like I want I’m getting noise from it when I have the volume all the way down but other wise my sons have them in they cars and they work

I really like this Bass Knob but I think the one that I received has a shortage or something.. When I turn up the bass it sounds really good and then whenever I take my hand off the Knob the bass reduces, if I place my hand back on the knob (without turning it) the bass gets strong again.
