Re: bridging amplifiers for dual 18 passive subs
Let's look at this.
When you run the amps the way you want to you blow drivers. But when you have less power-you don't blow drivers.
Seems pretty simple to me------------------------------
Yes most of the time when you parallel 2 8 ohm drivers you get a 4 ohm load. Typos happen in spec sheets.
The P3000 is 3600 watts into a 4 ohm load bridged.
In most "normal" cases with a pair of 1000 watt 8 ohm drivers that should be fine.
What exactly does the "1000 watts" mean? Is it continuous (or RMS as some incorrectly state), program or peak? That can make a HUGE difference in what the "real" wattage is.
HOWEVER it HIGHLY depends on how hard it is being pushed-what the program material is, how far into limiting you are and so forth.
With some music styles it is advisable to run the speakers at HALF (or less) of the continuous rating, due to the high heating and low dynamic range of the music.
