    sigh.....

    it's easy:

    you look at what RMS-output your subs have, @ what resistance and you buy an amp that matches up.....


    Oh, one more thing: cheap and car-audio don't go together. if you want something that'll last, you're gonna have to look for something $1 per watt RMS minimum (don't look at max ratings, they're worthless!!!

    and you said it yourself.. "cheap legacy" ... i would stay away from legacy and similar brands

    look for a class d mono (subwoofer) amp.

    If the guy was lookin at somecsheap crap, I wouldn't go xwith a class D mono. Instead, I'd go with a nice 2-channel amp and ridge that. That will be a much cheaper solution to a mono.

    just my $.02

    edit: what version of the H2 do you have? the D2 or D4?, if it's the D2 version, look at an amp that's .5Ohm stable. that way you can bridge the 2 channels and let the subs play @ 1 Ohm, which will have a positive result on your funds, because the amp doesn't have to be that powerfull as it would be when you're playing @2 Ohm or 4 Ohm....

    class d is however much more efficient and will handle the demand for a subwoofer channel much better than class a/b can ever handle.

    cardomain.com:
    "An amp's circuit design determines its class of operation. Class A amps sound great, but because of power inefficiency and high heat production they're used mostly for home systems, not cars. Class AB amps are commonly used in vehicles, because they provide low distortion, good reliability, and reasonable efficiency. Class D amps produce less heat, require less current, perform more efficiently, and are smaller than Class AB amps, but they tend to have more distortion. For this reason, they make great subwoofer amps since the distortion is almost impossible to detect in the low frequency ranges that subs play."

    crutchfield.com
    "A mono amplifier makes a great choice for powering subwoofers. They're specifically designed for low-frequency reproduction, with built-in bass boost and low-pass filters. Class D mono amps are often a good choice — they draw less current, produce less heat, and are more efficient than conventional amp designs."

    i can give you more cites if you dont like those sources

    you don't have to hand me any sources, I know my stuff. And yes, I know, a class D is much more efficient, but I was thinking along the line of the guy's budget since he was talking about a fleamarket brand in the first place

    Oh, and while a class D might be more efficient, the SQ is far less than with an A or AB.... Now, you might argue that doesn't matter as much with a sub, you're probably right. But a class D will also introduce more noise along the signal path, unless they found a way around that in the last, say, 2 years.

    while a class d may introduce more noise along the signal path, this signal path will be independent of the component (mid/high freq) channels. noise in the sub channel isnt easily detectable. in general, any type of noise is usually more of a grounding issue than the way an amp is manufactured.

    however, i do agree with you that if we are talking about an expensive SQ-competition setup, than yeah.. the smaller factors will matter

    100-200??? I'm sorry to have to tell you, but you'll never find an amp that has enough output for those subs.... Not even when you look at fleamaektebrands!!!! you need at LEAST 4000watts RMS (NOT MAX). It's flat-out IMPOSSIBLE!

    Now, I asked you a question earlier that's very important to detemine which amp you'll need. Do you have the ddouble 2Ohm version or the double 4Ohm version?

    If you have the double 2Ohm version, you'll need a 0.25Ohm stable amp that you can bridge at 0.5Ohm, or an 8Ohm amp.... Both hard to find, especially on such a low budget. WHat you could do is give each sub it's own channel. that way you only need a 4Ohm or 1Ohm amp.

    If you have the 4Ohm DVC version, you'll need an amp that's 0.5Ohm stable so you can bridge it at 1Ohm, or you could work with a 16Ohm amp (doen't know if you can still find those even, so that wouldn't be a good plan). Again, you may also give each sub it's own channel.... Then you'll need a 2Ohm of 8 Ohm amp.

    Now, for you to keep it a cheap as possible, in case you have the 2Ohm dvc version, look for an amp that puts out at least 2 x 2000watts RMS @ 1Ohm. In case you have the 4 Ohm DVC version, look for an amp that puts out at least 2 x 2000watts RMS @ 2Ohm



    EDIT: I searched some amps and prices, and the CHEAPEST I found that will ACTUALLY put out 2000watts RMS@1Ohm, is a hifonics BXi2006D. That one costs $348 and you only can power 1 sub off of it....

    they both are dual 2 ohm but i dont know what that stuff means exactly the amp i was looking at is on ebay http://cgi.ebay.com/ebaymotors/BLUE-...93451705QQrdZ1
