Hifonics XX Olympus: 125x4 at 4 Ohm RMS powering a set of Directed Viper 650 Components (Rear and Channels 3 and 4) and a set of Elemental Design 6500 Components (Front and Channels 1 and 2) hooked up to a DVD HU (attempting surround sound, but will mostly utilize for music).

http://users.marshall.edu/~adams111/Olympus.jpg

Channels 1 and 2:
Channel 1: 0 Degrees to 180 Degrees
Phase Shift: Off or Stereo or Mono
Channel 2: 0 Degrees to 180 Degrees
Impedance: 47k—0.6k
Freq: 40 Hz-400 Hz (or 400-4000Hz w/ Multiplier)
Multiplier: 1x or 10x
Crossover: HPF, LP, or Slave from ¾
Crossover: Full or Crossover

Input Mode: Channel 2 or Channel 4

Channels 3 and 4:
Phase Shift: 0 Degrees to 180 Degrees
Impedance: 47k—0.6k
Level: 9V—0.2V
Subsonic: 10 Hz—150 Hz
Freq: 40 Hz-400 Hz (or 400-4000Hz w/ Multiplier)
Multiplier: 1x or 10x
Crossover: HPF, LP, or Slave from ¾
Crossover: Full or Crossover

Overall for this Amp:

Bass Boost: 0 dB—18 dB
Bass Eq: 30 Hz—60 Hz
Q Control: Wide—Narrow

I know this doesnt really answer your question, but I dont think you can make dvc 2 ohm speakers into 1 ohm. You either keep them 2 ohm or you drop them to 1/2 ohm. You need dvc 4 ohm speakers to get to 1 ohm. I'm pushing 2 12" Orion hcca dvc 2 ohm with a Hifonics Brutus 1606 mono amp at 1/2 ohm. So if you only want to go to 1 ohm you need to get the dvc 4 ohm speakers.

Here's for dvc 2 ohm; http://www.crutchfieldadvisor.com/le...pedance=DVC2x2

Here's for dvc 4 ohm;http://www.crutchfieldadvisor.com/le...pedance=DVC4x2

They are 4 Ohm speakers, sorry for the misinformation.

Alright, your good then.

Its hard for someone to tell how to set up your amp. At best they could get you close, then you can fine tune it. Keep phase shift a 0*. I usually set the hz at 50hz and go down from there with 12's and 15's. I start around 80hz and go down for 10's. I have my bass boost down at 0, because with my setup I just dont need it, niether should you. I use the base **** to adj the gain where I want it when I'm driving around.

On my deck, I have the subout set to 50hz and keep the boost db down at -6. Which is as low as it goes. A lot of times I turn the sub off on my deck because its so loud.

The enclsure changes the tuning as well. The 12" Orion hcca's I'm using are in like a 2.5 cu.ft. (each) ported box. I'm using 1 - 4" x 12" port for each woofer. I can change the port to change the sound. A 10" port is for competition only (super loud), the 12" port is for really loud but the music sounds cleaner, and 14" port is for loud but the cleanest sound. I got that info for my speakers on Orion's website when I built the box. So my only other advise would be to do what the makers recommends for the enclosure. A .5 difference just in cu.ft. can make a big difference. Preference makes a difference as well. I just have the speaker in the recommended box. Whether sealed or ported.

Thanks!

How about:

Impedance: 47k—0.6k
Level: 9V—0.2V

Levels are the "gains," right? How aobut impedance?

Leave the impedance at 47K. Higher is better. Ideal is infinite. Ideal output impedance of the HU is a short (no impedance at all).

Level is the input sensitivity. There is no gain control on this amp (in fact, very few amps have a gain control. Most people don't know any better and call the sensitivity adjustment a gain because it makes the volume louder). If your HU has 4V outputs then set the input on the amp to 1.333V. At your max volume setting, you don't want the amp to distort.

EDIT: I haven't seen too many amps with a variable phase shift. Usually just a 0deg and 180deg switch. Wonder how they implemented this.

Here is my HU:

http://mobile.jvc.com/product.jsp?mo...hId=129&page=3

Looks like the the output is 2V--so what setting should I use? I have no ideal about the phase shift--seems like it is for balanced inputs, which I don't have though.
