Posted August 30, 200916 yr I have an aftermarket Pioneer HU (AVIC F900BT) and it has a sub control level (from 0 to 6) and bass boost (0 to 6). Would having a bass knob make any difference or is it the same thing as the bass boost on the HU?
August 31, 200916 yr If your pioneer is anything like mine the bass boost ups the bass to the sub and the speakers. Sublevel control is just the sub. A bass knob for an amp can vary from amp to amp.

August 31, 200916 yr Author It sounds like you need to adjust your gains correctly.my gain was probably 1/8 of the way turned up. is that ok?
August 31, 200916 yr It sounds like you need to adjust your gains correctly.I agree, and make sure everything is adjusted flat or to 0 when setting gains.

You need to set it the RIGHT way.ha i didnt set it! i got professionals to install it! but when i got my amp back to send it back for repair i saw that it was set at about 1/8 of the way up

August 31, 200916 yr Why don't you just do it yourself? No need to pay for something you can easily do.
August 31, 200916 yr Author Why don't you just do it yourself? No need to pay for something you can easily do.it should be free but if they do try to charge me i will do it myself
August 31, 200916 yr Why don't you just do it yourself? No need to pay for something you can easily do.it should be free but if they do try to charge me i will do it myselfMake sure they do it right...do YOU know how to do it?
August 31, 200916 yr Put the bass boost at 0. That is an actual boost at a certain frequency that will likely do absolutely no good for your system, and increase the chance of harm. The sub level setting, however, adjusts the overall signal strength to the sub amplifier. When you set the gain you'll likely want this at +6. That way you can adjust the sub's volume relative to the rest of your interior speakers from the drivers seat.A bass knob that comes with an amplifier can either be a bass boost or a gain control. Bass boost is the same as the bass boost on the head unit, generally not a good idea to use at all. But the gain control is like the sub level setting on the head unit and adjusts the total signal strength. That is the appropriate control to use.If the shop set your gain with the bass boost all the way up, they did a terrible job.

September 1, 200916 yr That way you have the ability to turn the sub down. If you set the gain with the level at 0 then increase the level to +6, you'll be clipping the amp.
