| In light of the new CP series of RF amps coming out soon, is the current T500-1BD, T1000-1BD & T1500-1BD being phased out for the new constant power series? Prices seem to be coming down for the current BD series of amps. |

Prices on the site were changed about 2 months ago - the new prices reflect "Manufacturer's Price" The authorized dealer sets their own price.
As far as the CP amps - yes they replace the T500-1, T1000-1BD, T1500-1BD and T2500-1BD. |

| The BD amps output changes depending on the load that the amp recieves, the CP series will put out the max rating no matter what ohm load that you put on the amp. |

| well, the CP will put out the same power at 2 ohms and 1 ohm. 4 will be lower, but who runs a 1-channel amp at 4 ohms now adays anyway. |

| Good to know, I thought the amps had the same output at any load. |

| so the new style is going to do the same as the JL audio amps have done for a couple years? And this is only going into the mono amps? Any chance it will find its way into the mulichannel amps? |

Hey Guys,
Just a quick clarification on our new Constant Power circuit.
Even though a speaker may be rated at an impedance like 4 ohms, the actual impedance varies with frequency. So as music plays through a speaker, the impedance of that speaker dynamically changes with the changing frequency of the music. With a conventional amplifier, as the speaker impedance changes, so does the output power of the amp. When the impedance rises, the power goes down, when the impedance goes back down, power comes back up.
The new Constant Power circuit closely monitors that dynamic relationship between the speaker impedance and the frequency of the music in real time. It then instantaneously delivers its maximum output power without regard to the varying load. This is especially important at the resonant frequency of the speaker where the impedance can sometimes more than double, which cuts a conventional amplfiers power in half.
The other amps that claim consistant (notice it doesn't say constant) power only look at the load impedance at power up, they then latch the power supply to make rated power at that impedance only. It stays latched there until the amp powers down. So at those impedance spikes I talked about above, the amps acts like any other conventional amplifier and loses power.
We optimized the circuit in the BD amps for 1 and 2 Ohm, 'cause that's where everybody runs them.
Later this year we will introduce a 4 channel full range amplfier with constant power. 250 x 4 @ 4/2/1 Ohm.
So in short, Rockford Constant Power is truly constant power, all the time no matter what the speaker does. This is a completely new way of doing things guys, the result is more SPL, and a much more dynamic experiance in your vehicle.

| Very cool explanation, thanks. I do have a question about them now after reading this (hope I'm not thread jackin') will the power output change with the voltage? In other words will these amps put out more power at 14 volts than 12 volts? |

thats what i thought jason... regulation on the output instead of the power supply
makes me wanna junk this T4kw for a T2500 CP and recone the woofers to 2 ohm |

thanks for the excellent engineering perspective and technical explaination of these new amps.
also, i like the first statement in my quote from you.
and in the second part of the quote, i cant wait and i hope to have enough money to buy one someday, it sounds like its gonna be awesome. |

The power supply is still unregulated, so yes, the more input voltage (up to 16 VDC), the more output. |
