whats real whats???

I am not experienced with audio on any sort. Only know the stuff i do know because and taking stuff apart and sticking this plug into that hole.

One thing that i have figured out is that every 500 watt amp isn't the same as other 500 watt amps. i know that there are 50 watt amps that will make a speaker hitt harder. what do you look for when you buy amps? i could tell you all the things to look for if you were buying computer ya know........ If you understand...........please help...

For sub amps, I look for RMS wattage at 4,2,1 ohms, whats teh lowest impedance it's stable at, make sure THD is under 1% at 4 ohms, crossovers, filters, subsonic filter, blah blah blah...

riiiiiiiiight....ummm...give me an example of what i would see on the box if i were to buy an amp.

my uncle wants to give me two punch 45 watts....but thats all i know right now.....is that a good amp .......if you know punch

it depends tho. if you get a mono amp (just one channel to drive sub) u would see like

200watts rms @4ohms

400 rms @ 2ohms

800 rms @1ohm Some amps overrate their amps n other underrate them.

on a class A/B (which r usu 2 channel or 4, but let's stick to 2 channel to hook to a sub). you would see

100x2 rms @4ohms

n then either

300rms when bridged, or 300peak when bridged.

take into account that we don't really give a **** bout peak power. RMS is the important number in there. Peak power is just the power that the amp can send at one point, n just one point, at burps i guess. while RMS is continous, i forgot what it stands fo, but somteihng like that. So just look at the RMS ratings, and if u hooking some subs it depends on how u wire the subs to run the amp at difference resistances (ohms)

wich is best........like a good ration i guess

ex: 300rms@4ohms or 300rms@1ohms

or: 100rms@4ohms or 100rms@1ohms

I don't understand what you are saying here...
Usually, amps that are one ohm stable put out a whole lot more power at 1 ohm then they do at 4 ohms...

As the impedance lowers, the power generally goes up, along with the current draw....

i think thats what i was looking for. the lower the ohms the more watts

ex:3ohms would be like 200 watts(rms) where as 1 ohms would be 800 watts(rms)....

Just saw a Soundstream Class A 10.0 for sale for $200. Don't know if that's what you need or if its even a good price, but he said it did 1000watts @ .5 ohm

oooook.........so there is different .."ratiings" other than 1-4?

Well, impedance is determined by the subwoofer(s)....example...if you have a SVC 2 ohm sub, it can only be ran at 2 ohms...

what is impendence..............we are dealing with someone who doesn't know anything ok....
