    LANZAR Opti SL800D

    What does anyone know about this amp? I have heard people say it is good and say it is bad, but what specifically are the comments about it? I cannot find any specific opinions aboiut it anywhere. I want to run it at 2 ohms to power one sub. I am looking for an amp that isn't going to draw a lot of power for what it puts out. Does anyone know the fuse it takes?

    If you don't like this amp, does anyone know another amp that puts out around 400 or more watts @ 2 ohms in the same price range (preferrably class d)?

    Thanks.

    specs i have:
    800 Watts x 1 @ 1 ohm
    Extremely Fast Switching Power Circuits
    Super High Current Output Stages Using Multiple High Current Mosfets
    Independent 24 dB Per Octave Hi & Low Pass Crossovers
    Wired Bass Jack
    Adjustable Gain Control
    Variable Bass Control
    4 Inputs Mixed to Mono For/FrontRear Fading
    Variable Phase Shift
    Variable Base Boost
    Dimensions: 10.8"W x 2.97"H x 9.8"L

    i don't quite understand why I would want "4 Inputs Mixed to Mono For/FrontRear Fading " for a sub. is this amp ok for a sub?

    IMO - $130 shipped off ebay it's an absolute steal.
    Some people have questioned the actual power especially being that it only has 2x20A fuses but if you know how fuses work you'll know they don't determine RMS power.
    Even if it's only 700w it's still a good deal.

    Re: LANZAR Opti SL800D

    so you think this amp will be ok for a dvc sub @ 2ohms? it seems to me like it is not meant for subs now that i look at the specs more. since it does only have 2x20 amp for fuses, does that mean it does not draw too much power from my car's electrical system, that is what i would like.

    Re: LANZAR Opti SL800D

    would i be better off with the MTX THUNDER421D? I like it's look better and it seems to put out the same amount of power for $20 dollars more. What is a better investment? By the way, is the 421D capable of 1 ohm if i wanted that in the future? right now, i am just looking for capabillity @ 2 ohms.

    how accurate are these specs? I have seen it only rated at like 300 RMS @ 2 ohms on different sites . . .

    MTX THUNDER421D
    210 watts x 1 at 4 ohms RMS 420 PEAK
    420 watts x 1 at 2 ohms RMS 840 PEAK
    Adaptive Class D Technology
    85 Hz low-pass crossover, 18 dB/octave
    Preamp outputs
    PWM MOSFET switching power supply
    Gain control
    Thunder EQ bass boos
    Speaker-level inputs with SmartEngage

    MTX is definitely a solid amp, but it's not stable at 1 ohm - or at least not intended to be.

    The lanzar will be fine at 2 ohms - it's actually designed for optimal power at 1 ohm. Not only is it MEANT for subs, but it's class D so sub amplification is all it's good for.

    If you're running at 2 ohms I think they'd be about an even trade - most people would probably say the MTX is worth the extra $20, but being a Lanzar fan, I'd probably go with the SL. Plus, I doubt you'll ever meet another person running the same amp which I think is cool

    Re: LANZAR Opti SL800D

    thank you for your help. i'm still a little unsure if which i'd rather have. i like the lanzar for the reson you have stated, but i have one thing i can't quite understand, i have never heard of having four rca inputs to an amp for fading reasons, i have another amp hooked up and my head unit runs the rear rcas seperate from fading so that will not be an issue. do you know if i have to hook all 4 rcas with a y or what? do you know anymore about this on mono amps? if you could explain it so i am clear I would appreciate it. thanks again.

    Still waiting for that pic Del

    BTW - It should be noted the 200.2 has an unusually large primary transformer for a 100x2 amp.

    Re: LANZAR Opti SL800D

    I'm the furthest thing from a high end amp connoisseur, but I could never imagine any other 100x2 being much better - even though I'm considering replacing it with a bridged 100.4. The thought of 250x2 to my front stage for the same price and size is just hard to ignore.

    The newer JBLs have 4 RCA's too. Basically for decks that don't have a non-fading subwoofer out. They usually work fine on two.
