0.5 smokes a kicker 12L7

[The Golden One]

ive been trying to find this video for a while finally found it, this is real power not just some sissy punk amp http://www.youtube.com/watch?v=XEKG__89rI0

[todd217]

that is pretty cool

[The Golden One]

you can see after they plug in the other rca it has some major excursion but then they smoke it there shortly after.

[ttocs]

they say it is "popping"? IS that clipping or some street slang for bumping?

dude that must be slang for bumping because i dont think it was clipping you got to be low ohming a zpa before you even think about clipping.

[Shinju]

well with no subsonic filter and probably clipping the shit out of sub on that song yeah that 10hz drop is going to mess something up eventually.

That song is pretty brutal with all the low frequency drops in it. We also do not have a clue were the gain/bass boost was set either.

Not saying that the 0.5 cannot be a brutal amp but alot of nubs blow subs/amps to shit to Bass I love you all the time.

[The Golden One]

dude you do know he's not even tapping into the power of the 0.5 your crazy if you think that, the only thing that is distorting is the sub itself it's just too much power. clipping is what you describe with weak amps that dont have the same kind of power as phoenix gold.

Ok what the hell do I know

im not trying to talk down on you man im just saying the zpa's are a totally different beast than other amps ive ran a 1000 watt 12 bridged on my 0.3 and it was moving 4 inch's of excursion the amp itself was not distorting at all but the sub was.

That's not true at all. A ZPA can clip just as easily at 4 ohms as 1 ohm. If you exceed the sensitivity, it clips.

Being that this sub was 2 ohms that makes it even more likely to clip, since the amp is 1/4 ohm optimized. If it runs in low impedance mode, odds are the gain will be cranked to offset the reduction in power, causing clipping. If stuck in high impedance mode (i.e. diode mod has been done), it is also very easy to clip.

totally agree.....
.5's are great amps and all, but they are not the be all end all in the power department IMO.
they were most likely clipping the crap outta the amp and sending the poor sub a square signal

i dont think he had the diodes clipped because it would have smoked that sub instantly and the only reason the amp would clip is if you send it a weak and dirty signal it's not a factor of power unless your not sending it enough juice for what your trying to do with it.

What is the power rating on the ZPA?

Sending a Square signal to a Square sub.... I see what you did there!

[The Golden One]

this is 710 watts rms of phoenix gold power from the 2125 http://www.youtube.com/watch?v=-gIbD-M-e0A the 0.5 is 1000 watts rms unmodded pheonix gold watts are watt for watt way better than brand x amps are.

A strong and clean signal could clip it too? If the sensitivity was dropped to .2v and the input was 8v, it would clip. ZPA does have a gain knob like any other amp, and like any other amp it can be made to clip.

ive not tryed that yet but i would if you let me borrow some speakers, i promise i will send them back minus the smoke that get's let out of them.

[ttocs]

any amp will can and will send a clipped signal. It has nothing to do with the speaker it is wired up to but with how the amp and the signal is driven, or rather over driven...

[Eric D]

A ZPA is just like any other amp, no real magic is going on inside. If you over drive the input like stated above, it will clip. I tested a ZPA 0.3 about a month ago and it could clip with a 2V input signal. It all depends where you put the gain setting and the input signal's voltage.

Blowing a sub does not necessarily mean the sub is junk either. Some of the biggest subs can die on small amps. It is a matter of installation and setup, not always quality of equipment.

I am going to get flamed for this, but here it goes- "Thats just stupid"- it isn't spl, it isnt sq, its just retarded- I have watched it a few times to find something redeeming, but there isn't anything there- it is amazing that the .5 can take that kind of abuse and not shut down, I guess that would be the silver lining to the thread-

[The Golden One]

im willing to bet more than half of the people making comment's about the 0.5 have not actually heard one in real life to me it sound's like some kind of phoenix gold sound machine. i assure you that if you can distort the amp itself then your really doing something. i can imagine the 2250 has the same kind of attitude as far as that lethal bad to the bone sound like no other.

[ttocs]

again, any amp regardless of power, or who makes it is capable of sending a clipped signal. The one will send one HELL of a clipped signal. PG amps are not anything magical.

I have owned pretty much every OS PG amp outside of a handful of the LE amps and some TA MS and newer Rodin/Octain stuff I have had a 0.3 and 0.5 ALL of them including the 0.5 follow the same laws as your cheap-O Walmart brand amplifiers.

EVERY amplifier has a THD level some are less some are more, I do not care how nice an amplifier is it can and it will CLIP if set up wrong, And I can promise you in that video that amp is being pushed well beyond its limitations thus causing it to clip and in the end blowing that L7 also you can HEAR the sub bottoming out on those 20-10htz drops in Bass I Love You with no Subsonic filter = death for that sub with how hard they were pushing it.

L7 subwoofers are not junk they are pretty well built and can take some serious abuse.

I dont know why you think PG is above the law and is immune to everything that other amps do. I like PG amplifiers but they are far from perfect and are not immune to clipping,distortion.

[The Golden One]

with that sub which is rated to handle 1000 watts rms the 0.5 should not have even come close to clipping here's why my 0.5 birth sheet says it's 1200 watts rms at 0.05 thd that means the amp would be way below audible distortion at 1000 watt's rms. but ok if you send the amp a dirty signal then you your self impose distortion upon the amp it's not the amp that's the cause. yes im sure it will clip past 1200 watts rms but where at 1400 or 1500 watts rms?

[ttocs]

i give up.
