    I'm thinking about picking up this model http://www.cardomain.com/item/PIOGM5100T

    It will be used to push a set of CDT CL61a's. Trying to stay around that price range for that amount of power (want at least 130w to each speaker)

    most pioneer amps are pretty "cheap" in my opinion. and 130W RMS to each speaker is a lot of power, you do realize. 100W is plenty.

    cl-61s are only 90 watts rms

    well.. from what i know, most amps over rate their power... the cl61s are 90w rms and 125w max. so i'm thinking any true power at least 90w will be good enough..

    unfortunately, don't wanna spend $200+ for an amp :hs: so looking for a cheaper alternative. just wondering if anyone has experiences with pioneer..

    in my experience, going cheap on the amp is not a good way to go.

    $200+ is actually not that much for a decent amp unfortunately. As far as less expensive amps go, I would say Phoenix Gold and maybe HiFonics are decent choices. Btw, the difference between 90watts and 125watts is very little. It would be something like a 10 percent increase in loudness. You would need 900watts to double the loudness from 90 watts.

    a used planet audio amp will be cheap and effective

    $79.50+ship

    will do a real [email protected] @ under 13v power.
    I have bought 3 from this guy all have worked fine. 30 day warranty

    pharcyde, how does the amp perform? any issues? i would rather get this amp instead of the infinity 310A...

    are they still good even though they are refurb?

    Yeah i wouldn't have bought 3 if i wasn't satisfied. Performs really well and no issues. The amp is a basic amp that does what it's supposed to do and does it well. Not like a bells and whistles amp but it has everything you'd expect

    phar, one more thing... do you power subs with this? i thought it was always better to have a mono amp? :shrugs: i guess ill go for this since its much easier on the wallet.

    Well right now i was planning on using it for a set of component speakers.
    A class A/B type amp though is perfectly fine for subwoofers. Just will draw more power from your battery/alt since class A/B are less efficient that class D subwoofer amp. Class A/B is 'cleaner' than class D whatever that means (no such thing as dirty power) but i think it's something to do with the circuitry makes them able to make subs sound better or that b.s.

    :ugh: that is a HORRIBLE statement. There IS such a thing as "dirty" power!!!

    First of all, analog sources follow a sinusoidal pattern. Digital sources follow a "box" pattern. That is dirty. That's only the most simple comparison. Look on google, my friend... Prolly find a lot of info on it. Also look at how a UPS or inverter works.

    Are we talking about distortion here or something else?

    Conventional feedback is the only way class A/B designs reduce distortion over class D designs

    what gauge power does it need? 4 or 8g?

    8gauge will work 100% fine, 4 is always better if you have it layin around since there's less resistance so less heat

    Heat isn't really the issue usually when choosing gauges in car audio. Usually it is because of the less resistance (which you said), leading to the amp being able to draw more power, and draw it easier.

    No such thing as "dirty" power? Are you kidding? I don't think you've ever looked at an oscilloscope.

    Btw, a class D amp will NOT make a subwoofer sound better all else being equal. It is simply less expensive to create a high ouput class D monoblock amplifier than Class A,B, or A/B. And, because subs require significantly (usually) more power than your mids and highs, it is nice not to spend a comparitively huge sum of money on a 500watt class A/B. The class A/B design should sound better than a class D.

    that's exactly what veonake said :rolleyes: Study ohms law a little bit.

    current requirements are static, with the same amp. Although current draw may fluctuate, we can say that the same amp will have the same requirements. Now, if we vary teh awg, we thus change the resistance... At a given current draw, with a different resistance, we can change the voltage.

    So he had an elaborate way of saying that a larger awg will lessen any voltage drops -- he simply states that this is through the decrease in resistance. Heat is the byproduct of resistance.
