Gain?

Is There Another Word That Might Be On My Amp That Might Be The Gain Could It Be Bass Boost Or Something Like That Or What???

sensitivity

On My Amp I Have A Few diffrent Settings And Im Not Sure Where They Should Be Set At The Setings I Have Are
I Level/freq The The Option To Be Set At Full-lpf-hpf/bass Boost/low Pass/ Hi Pass Where Should All Of These Be Set At And Are Any Of Those The Gain?

Level/Frequency should be the gain. next i believe is your subsonic filter, then your bass boost "sais it all in the name, boosts the lower freq. for more bass when set high. an next is your low pass hi pass crossovers...for subs set it at low pass

Well The Level And The Frequency Are 2 Different Knobs And All Of The Rest Im Not Sure I Fallow I Just Want To Know Where They Should Be Set At.... All The Way Up? All The Way Down? In The Middle?i Have No Crossovers Set Up Right Now I Have The Bass Boost Almost All The Way Up And Also The The I Level Is Set The Same I Have The (feq. Set At Lpf And The Hi And Low Pass Off.... I Want To Make It Hit Harder So What Changes Can I Make?

The "level" is your gain. But know this, gain does not mean the power of your amplifier. you have to match the gain on your amp to those of your head unit. What kind of amp do u have? do u have "hz" raitings on your freq? what kind of box are you running, an what is it tuned at?

Ok So It Would Be The I Level Then Right.. Is It Safe To Put It All The Way Up ? And Match It To The Head Unit? I Am Running A 2400w Legacy Amp Red Series I Know People Tell Me It's Crap..... And How Do I Know If I Have Hz Ratings? Also On My Deck What Shold I Have It Set To I Forget What It Is Called But It Might Be The Freq Im Not Sure But It Gives Me The Option To Put It At 80 Or 120 Which Should It Be At? As For The Box It's Ported And Facing Towards The Back Seat Is That Good? And As For As What It Is Tuned At Im Not Sure But I Have To 12 Inch Fosgates

Putting it all the way up and then matching it does not make sense. Each headunit is different. Honestly Hai,SR or a moderator have more knowledge about doin that. The 80-120 on your deck doesnt mean nething. You would probably notice a difference of more hard hitting bass if you turned the subs around an pushed the box back against the back seat. Do u have a trunk? or a hatch? wut i said is for a trunk

yeah i have a trunk it's a lexus LS400
