  1. Well first, I'd like to say hello, I just joined this forum. I just started with car audio a few years ago

    Here's my current setup in my 1997 Pontiac GTP

    • Kenwood KDC-MP345U Headunit
    • Kicker L5 15" in Ported Box ( Box not much bigger than Sub)
    • Kicker zx750.1 Amp
    • 2 GA Power, running off stock power sources
    • "Big Three" done under hood

    Here are the problems: The sub doesn't seem to be hitting as hard as it should. I have bass-boost on amp all the way down, gain on 8/11, and headunit bass flat. It doesn't hit fairly low notes, e.x. it sounds to be struggling to hit the notes in "Burn Rubber" by Too Short, and doesn't hit fairly high notes for this kind of sub, e.x. it half ass's the higher notes in "Top Back" by T.I. (not trying to tune my subs to songs, just trying to give easy examples)

    how olds the sub , you might have a bad coil , or the box is not tuned right. or like you said could be the ground wire your talking about. elimanate every thing you think it could be and see what you have then

    Here's what i think it is personally, the frequency nob moves, but doesn't seem to change anything sound-wise. Is this because there is a problem with the amp, or is it my headunit with the "Pass Thru option selected"?

    Also, my ground wire is a very cheap quality ebay 0 GA clipped to 2 GA. The wire strands seem thinner than the one's from my speaker wire.

    To add to note, The sub doesn't really flex at all tbh, although it hits, it does flex. When I had my older oldschool bd1000.1 amp, it flexed/hit hard, but amp overheated.

    Any tip, suggestions, or solutions? Thanks in advance. Great forum to be part of.

    try elimanating all things thats not done right like the ground wire an see if that helps
  2. Could fry it faster, but if your giving it rated or less than rated it only means it will heat up faster. Heat doesn't always mean fry and in some cases a warm sub could play better than a cool one.

    ive noticed that with my aq hdc. sounds better after its been played for a min or two. but its still kinda stiff

  3. From what i have learned from Ed Lester, Alum naturally heats up quickly and cools down quickly. These are best for burps.

    Copper takes a long time to hear up and a long time to cool. Best for daily.

    Could be the other way around, i forget now. :pardon:

    so would that mean that if you used a alui coil sub daily you could fry it faster than copper coil sub?

    [/quote thats right. i think

  5. I have 4 hifonics hfi's, rated at 300rms a piece. I can get a good deal on a 2600w Brutus, which does 1700w at 2 ohms. I am assuming it is overrated a little bit and doesnt actually put out 1700w. Would I be safe if I set my gains with a dmm or am I better off with a 2000w Brutus?

    i say go for it, im running 8 of those subs. and im putting around 1500 watts over and they do fine. but they will get a lil warm if you hammer on em for a while. ive smoked 3 of them in a few months time but there very cheap. so i try to kill em ever time. and they hold up good. if you blow one just get more. so i say hammer on.

  6. Im basically am looking for Deep bass over SQ .. Because i have my Mids and High which will take care of that ..

    Would you say that they are deep enough? Like i want Mirror shaking, roof flexing bass lol

    go with the re sx 18 deep bass and sounds good, thats what i had before i got 12s.
