I've heard of people checking speaker polarity this way, but I've never done it myself...so it's at your own risk. This is taken from Carstereo.com, and I ran a search because I couldn't remember if this test was supposed to be done with a 1.5 volt battery or something higher.

"Check speaker polarity
To make sure all your speakers are in phase, unhook the speaker you want to test at the amp (both wires preferably). Using a 1.5 volt battery (any size), touch the positive terminal of the battery to the positive wire going to the speaker, then do the same for the negative wire. Have a friend look at the speaker. If the speaker pops out, the polarity is correct. If the speaker pops in, the speaker is hooked up backwards (out of phase). To fix this, simply reverse the wires when hooking the speaker back to the amplifier. A word of caution here: DO NOT hold the battery power to the speaker for more than 1 second, all you want to do is to see if it pops in or out. You will damage the speaker if you hold constant power to it. Do not use a higher voltage. Also, do not try this test on tweeters, you could fry the voice coils. If there are crossovers with capacitors along the line, this test will not work (capacitors block DC voltage). Bypass the caps momentarily."

 

What is this high pass and low pass that you are talking about and how do I adjust that? Is it on the amp or headunit? I don't see anything on my amps that says high pass or low pass.

I see something that says off/hp/lp on my smaller amp for components.

 

He is referring to the HPF and LPF within the headunit. I did not know that the pioneer had this option, so I did not metion it. Most people tune at the amp unless they have a bad-a$$ head unit that has an active crossover built in (which according to him it does). I am not really familiar with Pioneer products, I use mainly Alpine. I had all my active cross over settings saved in my old Alpine 7995 that was tuned with a laptop (not sure of the software..... "pink noise" or something like that maybe?) at a local shop.

These are just what I have found to be the best with my current setup (Alpine iDA-X001 does not offer any real tuning capabilities) in terms of reducing low-end high-volume distortion on my speakers.

You can test polarity by just hooking the wires up, and seeing if the sub "pushes" or "pulls" during a bass hit. If it pushes, its reversed. Chances are the colored wire will be positive, if it was "normally" wired...

If you PM Albert, chances are he will still get an email that he has a PM, and will probably still check it.
