    Wattage increase, boost decrease

    I have two 10" subs that can handle 500 watts rms a piece. I got screwed into buying a crap amp and it turns out that I am only running about 28 watts rms to each sub. I also have the bass boost switch on and it says +18db. Obviously, with the combination of the two, the sound *****, but it's decently loud. I just got an amp that can safely give each sub around 450 watts rms, but the boost only goes up to +10db. I am aware that it can cause damage to run the boost all the way, but which setup would be louder, and by how much?

    You don't want to use any boost. It sounds like you were clipping your signal. Which amp do you have now? It is important to set your gains as best you can, some say a digital multi meter, others will say an oscope is better. Also no bass boost, there are some on here who may be able to help, might even find someone local to you. Good luck dude. I just realized I am fairly close to you, in Trussville. Shoot me a pm.

    I have a lanzar amp (VCT 2010) which I bought because I couldn't afford a better one at the time, but will my subs be as loud with 450 watts rms instead of 28 watts each, but without the bass boost?

    all things being equal and accurate, by increasing your power over 10 fold you should easily be a LOT louder.

    Bass boost is ****, don't use it. Especially if you don't know how to set your gains correctly. You're going to fry your amp and subs.

    Grab a DMM (or an oscilloscope if you have access to one) and follow the appropriate guide for setting your gain/input sensitivity.

    It would help us if you listed your old amp, your subs, and how you have them wired up.



    My Setup:
    • Head Unit: Kenwood KDC-BT555U
    • Speakers: 4 Kenwood KFC-P709PS components on a Rockford Fosgate Punch P400.4, ~70W RMS @ 4Ω to each
    • Subwoofers: 2 Rockford Fosgate Punch HE2 12"s in a custom 2.5ft³ sealed enclosure on a JBL BPX500.1, ~750W RMS @ 4Ω to the pair

    Re: Wattage increase, boost decrease

    So would 450 watts with 5db bass boost (half) be louder than 28 watts with 18db bass boost (current setup)? I'm just trying to figure out what to expect when I switch amplifiers from a junk lanzar vector to a hifonics brx1600.1d

    Also,there is a remote that comes with it that has a knob that goes from labels minimum to maximum. It says boost on it, so I'm guessing its bass boost, but I've also read that it is used for gain. Which one is the control knob used for

    Like already said a few times. DONT use the bass boost at all.. Keep at 0. Go with the PPI BK1800 over that hifonics.

    You will not need any boost of any sort when you switch amps.should sound much louder with the better amp alone

    Re: Wattage increase, boost decrease

    Yeah with my old setup, the bass would max out at 10 and the volume could go up to 45 so I'm guessing that's not good at all
