    run 6x9s and sub on ppi900.4?

    The lower the ohm load the warmer the amp gets. Some thoughts.. a Coax speaker may not be a 4ohm speaker. Should check it with a multimeter. If it is like 8 or 6.. You could run them series you could get like a 4 or 3 omh load. You should try to avoid using an amp channel to support both full...

    Precision Power PPI 2300M vx 2150M

    Why was the 2300M so expensive, or even made? The amp is basically two 2075M's put into one case. It can not be bridged further, it is only rated at 300W x2 @4Ohm. There is no rating for 2 ohm.. A 2150M was rated 150W x2 @4ohm an 300W x2 @2Ohm, could be bridged and get 600W x1 @ 4ohm. So what...

    Muffled and Distorted Bass on Certain Tracks

    Again. Said it twice. Verify the size of the box. Verify what the woofers need. The companies publish their stats on the speakers. Just make the box fit ideal conditions for best results..

    Muffled and Distorted Bass on Certain Tracks

    I have seen video's of that and it works in improving SPL. Have you calculated the stats of your speaker to see what type of air space they need. Or you just got a box and put the speakers in it? The sealed chamber is to support the speaker to help the speaker respond. If the space is too...

    Bandpass, ported, or sealed?

    Too many variables to give a black and white answer. 1) what is desired outcome.. Accurate bass, Low bass, SPL? 2) how much space do you have to deal with? 3) certain speakers tend to perform better with one type of enclosure than other types.. Just got to see what the company recommends and...

    Just acquired a bunch of old PPI amps and need info

    As I said I am going to run the subs in separated chambers. So they will not be canceling or competing with air. As long as you separate the woofers so they are in their own environment they will perform the same as if I only had 1..
