[QUOTE="HardofWhoring, post: 8860987, member: 674149"] 🙄 The remote knob might just be bad. It's not required, so take it out, and set your gain. If you then put it back in (at full), and it does something different, then something is wrong with the knob. Those 3.5mm jacks are always sketchy. You can try a different one, but if it's the connection on the amp, the easier solution would probably be to just get a remote knob that is on the RCA wire. You would wire this inline, so you're most likely going to need another set of RCAs. Then you can mount this where it's convenient. There are several styles. Here are the ones I'm using. [MEDIA=amazon]B003FPD3IS[/MEDIA] Low pass filter is what frequencies can pass lower than the filter. If you don't know the targeted frequency range for the sub, just set it as high as it can go, 300hz, and everything below 300hz will not be filtered out. You can play with it after that if you have a targeted range, but for a 150w sub, then don't worry about it. The level (.4v -4v)I don't see a picture, but that should be your gain. It's trying to match it up with your head unit's preout voltage. There are better ways to do this if you have a multimeter. If your head unit has 4v preouts, you set it at 4v, and you're sending out the lowest power that amp can do. I don't know the specs on your amp, or if that sub is 250w max or RMS but I would suggest instead of that, do it this way to match up with RMS rated power. See how close you can get, and how that works. [MEDIA=youtube]gg2gl-fz2Qc[/MEDIA] [/QUOTE]
