RE audio SE12D2

[ErwinM619]

i guess this guy with A.A.S. degree in Electronics/Industrial Electronics with 25 years in the mobile audio/consumer electronics field, Peavey Media-Matrix certified audio engineer is wrong according to the people saying that under powering subwoofer can damage it...my god someone needs to enlighten this guy that underpowering subwoofer is bad!!!

You need to run a Re Audio SE sub at 600 watts REAL RMS...NO Sony amp will put out close to that no mater what the LABEL Says...lol

yeah he can run it for a little while on the cheap amp just dont turn the gain up to high he should be ok ..... and dont listen to it to loud... he may be good....

wat kind of amp r u running? i actually got my eye on HIFONICS BXi-1208D

wat size is that box? my box is about 3/4 of urs

[jobab06]

2.5 ft @ 30hz its all painted with bed liner paint now so it look way better now

bedliner=very creative i've never seen that on a subwoofer box b4...u should post a pic of it sometime

[jobab06]

yeah sure will once i pull the pictures off my phone

Cool btw wat size is ur sub and wat amp r u running? i'm on the market of buying a new amp not because someone told me that underpowering an amp will fry my subs which is a total bullsh*t

[jobab06]

its a 12 ... at the moment am running a 45 dollar best buy amp i got off ebay it only getting like 300 rms but i don't trust that amp so i have the gain set pretty low and don't have that bass boost shit on so it does not clip ... am waiting to get this but

but school started back and i need like 400 dollars in books so that's what i have to get now .... so that amp will come soon.

that amp is perfect if u got the 2ohms cause u can wire it up to 1ohm and get 600wrms...how is ur sub hooked up on ur previous amp?

[jobab06]

the sub is a d2 so i have it running in 4 ohm now because my cheap ass amp would probably catch a fire because it is not 1 ohm stable ... so yeah that other amp would be perfect.

Underpowering a sub will not kill it, period. But like every one else said, save your money for a better amp.

you could blow speakers by underpowering them,the voice coil will overheat,causing it go, heres a more tchnical explanation,


When an underpowered amplifier "clips" or runs out of steam and the power supply can no longer provide enough current to the output tubes or transistors, or when those devices reach their maximum output voltage, the signal gets clipped. The waveform of the output then contains a huge amount of DC voltage, sometimes at very high voltage levels relative to the levels seen when the signal is behaving itself as AC.
This DC voltage (and the other trash thrown out by the clipping devices) is what does the damage.
The voice coil of a speaker is actually a motor. When it sees DC current, the motion of the voice coil stops, or "stalls". When this happens, instead of acting as an inductor, the voice coil basically becomes a piece of wire, and the amplifier sees that piece of wire as a dead short. This causes a spiral of death. The short demands more current from the amp, which it can't deliver, and it clips even harder. Meanwhile the voicecoil is heating up from the increased current, and the lack of any cooling fanning motion, and poof - puff of smoke, and no more voice coil. Even a microscopic burn can sometimes kill a voice coil.
This is why, when used and applied properly, it is always better to have more amplifier than needed. Clipping is much more destructive than a small amount of overpowering.
One last note - loud is not always better, but the only way to get really loud is to have a larger driver, larger box or more boxes. A bookshelf teensy driver and billion watt amp is never going to push the air mass that a big box and an appropriate amp will move.

doughboy, thats not underpowering it, that the amp being too weak and clipping because the gain wasnt set right. what happens is that newbs just crank the gain because to them it gets louder which is better, and then it clips.

its not underpowering, or else id be underpowering my shit daily when i turn it down.
