OKI have a Rockford Fosgate 451s and a pair of Infinity Kappa 692.5 6x9's. They have crossovers that come with the speakers how do i set the crossover on the amp. Also the amp come with the Remote punch base how do i set that and can someone explain what that really does?

The output from the amplifier connects to the input on the crossover. The woofer and tweeter in the coax set connect to their specific outputs on the crossover. The "Punch" circuit is a bass boost. ------------- Support the12volt.com

On those speakers you can just keep the amp on either full pass, or turn it on high pass but set the crossover low, around 50 hz if you have no sub and if you do have a sub than set it around the same point as the subs crossed over, I hope you understand that, I cant think of a better way to word that but it sounded kinda confusing. And if you are just using the amp for speakers than dont even bother with the punch bass, just set the amp properly and leave it be. I dont even know if that control works unless the amp is set up to run a sub on low pass, I never tried it.

Well I guess I didn't read it carefully. I'd set the amp to full pass without subs. If the speakers break up with loud bass passages, then activate the high-pass filter. ------------- Support the12volt.com
