Mattk11 Your front four speakers will use a high pass and the sub will use the low pass filter. Both should be set at the same frequency or overlapping a little but never with a gap between them.

Depending in the size and capability of the sub you can try these:
8" sub - try 100-120hz for both LP and HP
10" sub - 80-100hz
12" sub - 80hz

louczar There is a removable cover plate on the opposite side from your speaker connections on the amp. Under the cover, you will find controls for Ch 1/2, Ch 3/4 and the sub. Ch 1/2 & 3/4 should have the "filter"switch set for off depending on the type of speakers you have connected.

The LP filter (low pass) is straight forward for the frequency cut off of what will be for the speaker. The setting you want will depend on your taste and what your speaker will do. Look up what sub you have and see what its freq range is. Set the LP filter for that value aor lower depending on what you like. If the speakers in the front and sound bar are full range, then don't change anything else.

lowreyfarris Normally I keep my sub around 80-120. If you have the stock 5.25 and 4x6 in the dash and roll bar you probably want to keep the crossover off on those channels off.

I do run my sub crossover (a single 10") a little higher in the jeep than in other cars, because their is quite a void between it and the other speakers when I run it less than 100. I have replaced the factory speakers with Kickers, but the location and size are really limiting.

I listen mostly to rock if that helps.

help with amp cross over settings

I am not very knowledgeable on stereo systems. I have an alpine head unit and a PDX alpine amp. The amp I believe is a 5 channel amp. sub and two channels for front speakers and two channels for the sound bar.

My question is how do I set the cross overs on the amp. I have had the system for a couple years and tried different settings but I really would like to have some that knows, tell me how these are supposed to be set.

Thank you - John
