Help with RMS x Wattage?

[DbGottEm]

So I have 2 15" subs with Peak Power @ 1200 watts and a RMS rating of 600 watts.

They are Dual 4 ohm Voice Coils. What Wattage of amp am I looking for? Im Guessing about a 1200 to 1500 watt?

Forget bout the peak power, all you need to know is the rms. So what you need is an amp that runs at 1200w at 1 ohm. When you wire them in parallel/parallel they will be down to 1 ohm. The power of the amp will be split between the two subs.

Could I also run a 1500, ive been told you can run as high as 150% more power than the rms. True or False?

It really depends on the subs if they can handle more then rated but I doubt an extra 150w to each sub will do any harm and I doubt you notice a difference.

Running 25-50% more power than rated is almost always safe but like said above, it depends on the speaker. Some subs are happy at double their rated power and some subs will run hot at rated. It all really depends on build quality and how the manufacturer derives their power ratings.

Also, if you will share the brand and model of the subs and what kind of box you plan on using them in, you will get a much more accurate and beneficial response to your questions. In short, the more info we have, the more accurate our advice can be. ;-)

If you have $1200+ to spend on a good amp and batteries to support it get as much power as you want. Power doesn't blow woofers, distortion does. The more overhead you have the better. Thermal power ratings are almost useless IMO

I hate when people run non enclosed sub boxes
