I'm going to be running a PPI 2300.2 amp which is rated at 150watts/2channels at 2ohms to my Infiniti Kappa 6.1 components, which is rated at 250 watts rms at 4 ohms. Should I run the speakers at 4 ohms, and if so, how do I go about wiring them to do this? The instructions say the amp will power the speakers at 75 watts at 4 ohms, but there's no information on how to wire them to do this. Do I just wire them in parallel?
Run the wire from the amp to the crossover input, than you'll see W+ and W- and T+ and T-. Just run speaker wire from W+ to the Woofers positive and W- to the woofers negative. The tweeter shoild have black and red cables run theblack/red cable to the neg and the all red cable to the pos. You don't need to wire the speakers in parallel or series. Just straight up wire them.
You'll have to get a volt meter and touch it to the wire. If the amp says they'll only be getting 75 at 4 ohms then thats what they'll be getting. I have mine running at 100 watts, and they're doing fine.
