I've had an entry level system for about a month now. Two MTX 12's, Rockford Fosgate Prime R-500 watt amp, stock car speakers (for now) and a decent Kenwood head-unit that has a nice spread of subwoofer adjustment options. Nothing fancy but it sounds great. My question is this: The amp came with a bass adjustment knob that can be plugged into a jack on the amp and run to the dash by a cord. The manual calls it Remote Punch Level Control. From what I understand this will let me control the gain from the driver seat. My friend didn't mention this while he was installing my stuff and I can't ever get a hold of him. The only reason I'm considering this is because I hate flipping through Kenwood bass adjustment menus while driving, and a little dashboard knob would be nice to have. I listen to alot of different music so my settings need to be screwed with once in a while. I know there are alot of experienced people here and I need your opinions. Is this dangerous since it'll constantly be messing with my gain? Thanks much for your time.
Yes I feel the subwoofer knob is a necessity. It seems the amount of bass on each CD is different. And even some songs on the same CD vary. I'm always turning mine. Fortunately my Clarion EQ has the sub level control so I didn't need an amp that has it. I love my Alpine MRP-M500, but no remote knob on that one. If you listen to different kinds of music, you'll love that knob and wonder how you got by without it!
Depending on the amp, some knobs control gain and others control bass boost. Most are just gain controls. However, I've seen some Fosgate amps that, oddly, won't produce as much gain unless you plug the control in. Normally, it shouldn't limit the maximum, but some of theirs do.
