Hertz system help!
 

Ok so I'll let you guys know what I have for hardware.

Amplifier: Hertz HDP4 http://www.hertzaudiovideo.com/car-a...plifiers-hdp4/

Components: Hertz HSK 165 http://www.hertzaudiovideo.com/car-audio-speakers-system-hienergy-hsk165/
Coaxial 2-way: Hertz HCX 165 http://www.hertzaudiovideo.com/car-audio-coaxial-hienergy-hcx165/
Coaxial 3-way: Hertz HCX 690 http://www.hertzaudiovideo.com/car-audio-coaxial-hienergy-hcx690/

So my question is. I want to run all this equipment off that amplifier. I'm not sure if this is possible but, I was thinking I can maybe parallel the HCX 165 and the HSK 165 to get 2 ohm on the front channel and then run the HCX 690's alone on the rear channel at 4 ohm.

Someone let me know if i'm delusional :P

I could run the coaxial pair together aswell at 2 ohm. Incase 2 ohm would hurt the crossovers or something.

Ok, so you have 6.5 components for the front and 6.5 co-axials as well for the front? If you want to be able to fade, then run the fronts parallel (2 ohm load @ 250 watts /channel). This will give each speaker 125 watts, and the rears at 4 ohm @ 150 watts/channel giving them 150 watts each. There is no problem with 2 ohm and your crossovers etc.. as the amp is seeing the load, your crossovers and speakers are just getting power. The only potential issue is the slightly higher level of distortion and noise the amp will produce at the lower impedance, but from my experience it's inaudible..at least in a typical auto install.

Thank you for the reply. I'm doing 6.5" components in front and in rear doors 6.5" coax and 6x9's behind rear seats. So I've decided what i'm going to do now is put the 6x9's on the rear left channel and the 6.5" coax on the rear left channel. Since I want to make sure the dynamic impedance is at least equal. I think it should work plus your reply makes it more concrete so thank you :)

Ok, in that case put the components on front left and right to get max clean power to them as they are your main speakers for clarity, stage etc... Then, put rear doors and rear 6x9s on rear left and right amp channels in parallel. This allows fading and distributes the amps power in the best way to maximize sound quality.
