Amp Crossover Help

[poorblackman]

I will be getting some 4 inch Polk dxi400 speakers put in soon along with the Alpine MRP F300. I was curious to know what should I set the High Pass Filter to? I was told that it wouldn't be a good idea to try and get any bass out of the speakers and that I should set the HPF to about 400hz. Is this correct, or are there any other suggestions out there? Thanks!

Depends. What speakers are in your car altogether.

At high volume levels I wouldn't run them under 400. 300 probably the lowest depending on Howe your going to dive them.

I am putting the Polk dxi400 speakers in all 4 of my doors on my 1996 Toyota Avalon. I am also getting a mono amp and a 10 inch sub put in, so I'm really just trying to get some ideas on a crossover set up for my system.

80 hz lpf for subs

80 hz hpf for front doors

80-500 hz bpf for rear doors. If you can't bpf rear doors just use the same add front doors but turn them down some.
