What you're looking for is called a "crossover". A crossover is an electronic filter for an audio or speaker circuit. In an audio circuit, a crossover is used to prevent or pass certain frequencies or a range of frequencies from passing through it. Since your sub will reproduce the bass or low frequencies, you don't want other speakers to reproduce them. A band pass filter on your door speakers will do this for you. A band pass filter passes only a range or "band" of frequencies and blocks those that are above and below the range or band of frequencies selected. Installing a band pass filter will prevent the very high & very low frequencies from getting to the door /dash speakers. Likewise, you should consider connecting a low pass filter to your subs, too. The low pass filters work a little differently from of the way band pass filters work - they only allow low frequencies to get to the sub - blocking all the other higher frequencies (your other speakers are better suited to reproduce those). Lastly, you would install a high pass filters on tweeters. Tweeters are designed to reproduce only the high frequencies - sending mid and low frequencies to them is wasting power and can cause damage to them.
You purchase the filters for specific crossover points (the block / unblocked point) as determined by the individual speakers. If a sub has a frequency response of 20Hz - 100Hz, a low pass filter of 100Hz would be ideal. Remaining filters would need to begin at 100Hz - assuming the mid-range speakers have a frequency response beginning at 100Hz. A band pass filter of 100Hz - 3KHz would fit the bill nicely if the mid-range speakers go up to 3Khz Match the high end of the band pass to the high end of the frequency response of the mid-range speakers. Next, a high pass filter at 3KHz would allow only the high frequencies to your tweeters. Basically, you want to have the entire audible range 20Hz - 20KHz covered by the speakers and have the crossover points that match the frequency response ranges of the speakers.
Walmart sells a 760 watt 2 ch amp.....It works well with these type of subs. Or any amp rated @ 150 watts per channel RMS. Start with the low pass filter on and with it hooked up and playing raise amp level until distortion can be heard through subs...then back off a bit...Your level is now set.
try this site very hepfull if you can find all the speakers spec's.http://www.ajdesigner.com/speaker/ajvented.php . if you have the latest pioneer speakers they were designed for small enclosures if you imput speaker code in to google search you should find all the details you need .
try to use the preset equalizer settings after which you can come back to the parametric equalizer and adjust to your own taste. no problem if you don't connect the subwoofer just make sure you set the hi-pass filter to off so that you will hear the full range to your speakers. but, I advice you to put a subwoofer. There is more dynamics to the lower freqs too. don't adjust the source level if there is no problem. take note the EQ of your head unit is a parametric equalizer. hope this helps while you read about parametric EQs.
I would try walling it up unless you are going to buy 2 brand new subs. the problem is the older power subs had such small magnets so they needed alot less air space inside the box. Unless you can find the EXACT subs this box was made for I would recommend chopping it and doing a single sub. if you try a replacement sub go with the 12" P1 series they are a close match for the power 12's of the past.
Their is a chrysler amplifier some where in your pacifica.In order for your signal to reach the speakers you need to buy a box (from bestbuy install ,or any car stereo install place)that allows the signal to "pass thru"to the speakers.
If you know how to use a multimeter, you can test the amp this way:
-unhook the subs -hook up a cheapie speaker you know for sure works to one of the channels -unhook the audio inputs -turn the amp on -set your meter to VDC -put the positive probe on the inside of the input connector, being sure you make contact with th inner contact -take the negative probe and tap it on the outside of the connector
you are doing is sending a low voltage (replicating an audio signal)
into the amp audio circuit and allowing the amp to amplify it. If the
amp makes the speaker pop each time you strike the probe, the amp is
There is an inherent problem with band passes. The naturally filter out high frequencies like a crossover, including distortion, so it makes it hard to hear when the subs begin to protest.
Recommended volume for these speakers is 1-2 cu ft each speaker. Best materials are marine grade plywood and epoxy resin/matting. decide what space you think you can spare and see if you can make a box that will be about the right size in the space. always try and leave as much space behind the speaker as the speaker takes up from the front. look at the link below for some ideas of the ready made boxes you can buy.
the speakers you have will need at least 2 one inch ports each in the back of the box, or equivalent. completely sealed can have bad effects on these speakers at high volume. I personally recommend keeping both subs in a seperate box completely, but a good solid box with a divider will probably work - make sure that no holes of any size exist between the two as this will cause distortion with certain channel set ups and is best avoided although some good results have been achieved with back flow between sub sets - it is a bit too hit and miss to be worth trying.
