    Amp question (new to form)

    Hi guys new to the form! Had a question about my amp!
    A little background of my set up
    F150 extended cab stock electrical
    5.4 cube box ported and tuned to 36hrz
    Kicker l7 15 sub and box have replaced back seat and is firing up
    Alpine deck with external amp running door speakers ( not problem)
    Problem is sub amp hifonics brz1200 wired at 1ohm
    This thing makes that l7 hit like crazy when the gains are all the way up but of corse the sub starts smelling and I shut it off right away. If I lower the gains below half the sub doesn't really hit but it no longer smells!
    But this ***** cause I can't have the sub hitting like it should be!
    I have the deck set at zero for bass
    My question is if I upgrade to a REAL AMP kicker zx1000.1 will I be able to have the gains set low and have the sub hitting like it should be without the smell of the coils burning? making clean power

    Basically what I'm getting at I'm assuming I smell the sub because the hifonics amp is putting out dirty power and clipping
    Will switching to kicker fix my problem!
    Forgot to say I'm running 0 gage wire for power and ground monster cables from deck to amp RCA if any of that helps and stock electrical! Yellow top battery

    Re: Amp question (new to form)

    if your gain is turned all the way up you are for sure clipping. The gain is based off of what sub pre-out voltage your head unit is doing. If your pre-out voltage is 4volts then you want to match your gains to 4 volts. This is so your head unit and amp will reach it's max volume output at the same time. I'm running 1 SA-10 Subwoofer and my amp gain isn't turned up over 1/4 of the way. Try finding someone with an SMD DD-1 if you want it set properly otherwise put it at like a 1/4 and adjust settings on your deck.

    Re: Amp question (new to form)

    I understand that I am clipping with amp gain turned up all the way but what I'm saying is that it's the only way to get that sub moving like it should!!!! If I'm only a quarter of the way up on the gain the sub is barley moving! So my question is will a kicker zx1000 or even zx1500 get the sub moving like it should with the gains up only a little? Or is my problem at the deck and the volts it's putting out!

    Re: Amp question (new to form)

    if you look up the specs of that deck it will tell you the voltage pre-out, how many volts. Also is your L7 a dual 2 ohm or dual 4 ohm

    Re: Amp question (new to form)

    Also would buying another deck with a higher volt pre out help?
    I only keep the bass at zero out of +7 is because if I turn it up to 7 my door speakers become distorted!

    Re: Amp question (new to form)

    ok found them. your deck is a 4 volt pre-out and looking at the amp settings this is what I would put them at just based on my experience.

    Level knob at 1 oclock position --- phase on 0 degrees --- bass eq at 11 oclock position --- subsonic on 15 --- low pass at 9 oclock position

    then if you wired your sub in parrallel you will either be at 1 ohm on the sub meaning its a dual 2 ohm sub or at 2 ohms meaning a dual 4 ohm sub. if its at 1 ohm you'll be pushing 1200 wats to the sub if its at 2 ohms you'll be pushing 900 watts to it. And your sub is rated at 1000 RMS. so ya

    Re: Amp question (new to form)

    your deck should have a sub level selection as well so look into your deck manual and find that. bass level is overall speakers, sub level is just the sub, so find that on the deck

    Very false statement.

    Re: Amp question (new to form)

    Yes it is at 1ohm
    Yes the deck is a 4 volt and I've had the settings on the amp at half way but it just doesn't hit like it would with the gain all the way up! But I no I'm clipping when I do this! The sub really hits though! So maybe buy a zx1500 and through 1500 watts at it? Then maybe it would hit like I like? Cause the sub isn't even hardly moving with gains set like how you described!

    increase your sub level on your deck with those settings on the amp as described.
