50 watt RMS too much of a difference?

Question

my 2 subs are rated at 800 RMS and my amp is only 750 RMS, is this going to be underpowering them, or i am okay? I dont plan on playing them full power all the time

Answer 1

You'll be fine, but I disagree with the guy who said over powering will blow speakers.  Overpowering can be less dangerous on your speaker then underpowering, depending on your level of understanding of electronics.  I overpower all my stuff.  Usually by around 2x.  Meaning, if my sub is rated for 600 wrms, I'll run around 1,200 wrms to it.

Answer 2

NO,

You should never fully power the sub/speaker.  That is a good way to blow them

Good Luck...

Answer 3

If you send too much power to your sub, you risk damaging it. The cone of the speaker and the mechanical parts that make it move may break under the stress. Surprisingly, too little power can also damage your subwoofer — in fact, it's actually more common than damage caused by overpowering.

When the volume is turned up and the amp doesn't have enough power, the signal becomes distorted, or "clipped." This distorted signal can cause parts of the speaker to overheat, warp and melt. Not good!

You don't have to match speaker and amp wattages exactly. An amp with a higher output than the speaker's rating won't necessarily damage the speaker — just turn the amp down a bit if you hear distortion from the sub and don't run the speaker at extremely loud volumes for lengthy periods. Likewise, you'll be OK with a lower powered amp if you keep the volume down and don't feed a distorted signal to the sub.

you NEED to set the gain (input sensitivity setting) CORRECTLY, regardless of wattage (too much, exact, or not enough) the gain needs to be set properly so that you do not send a distorted signal to the subs, it the MAIN cause of sub damage

Answer 4

You're ok. It won't hurt anything. The speakers RMS rating is just what they're capable of handling on a consistent basis. However, If you want to get a bigger amp, do it soon, otherwise switching to a larger amount of power than what they've become used to could cause them to not function properly.
