Dodge Stratus Wiring

  I have a 2000 Dodge Stratus ES with the Infinity premium sound system that I want to add subs to.  I'm not having any luck finding a wiring diagram for this system.  The problem is...there are about 6 outputs from the head unit....and 12 inputs to the amp under front passenger seat.    What's in between?  also each of the rear 6X9's has 4 inputs, are they dual drivers?.  I also needed the impedence of the speakers so that I could build crossovers if necessary.  Any help would be greatly appreciated.

Thanks

Hi Jim, use a voltage/ohm meter to measure the nominal impedance of your speakers. Set the meter to measure resistance (X1) and place one probe on each terminal of the speaker. The reading will be the speaker's nominal impedance.

BTW, are you sure the amplifier is under the passenger's seat and not located under the rear deck in that vehicle? I seem to remember them being under the rear deck or elsewhere in the trunk.

Thank you the12volt....hmmm, I thought the impeadence of a speaker was a reactance...not a dc resistance. I will measure it with a multimeter then. And yes....the amp's under the front seat. I took it out to be sure, and it'a an audio amp.  It  has all the correct color wires that come from my factory head and I traced the outputs to my speakers..

Thanks again the12volt

"but I still need passive x-overs for my rear 6X9's (so I don't waste valuable amp power on unnecessary frequencies)"

Unfortunately, if it's a passive filter, it's not going to keep you from producing those frequencies. The amp's goign to put the ferquenciues out, the crossover just filters then out, so only part of the siganl gets to the speaker. The amp still pushes full range and uses the power. I assume you meant a passive after the amp and not in the amp's signal, as you were asking about impedances.

My suggestion would be a set of Harrison Lab's F-mods beofre the amp. You could wire them into any line-level signal. before the amp. They'll do exactly what you want to do. And save your amp's power. Get them Here: http://www.hlabs.com/products/crossover/

Good luck!

Wow, Thanks NyxBass, I would try those, but...my main problem is that 100hz and below is still going to my 6X9's and causing clipping at those frequencies before my sub volume gets to potential. And since I'm tapping the signal for my sub off the 6X9 speakers , those type of filters will affect the 6X9's and my sub. I was hoping to tap before an inline pasive filter....allowing those freq's to my sub only.

If I were designing a whole new system, I would try those....but since I'm keeping my factory radio....I'm looking for other alternatives. Maybe I'll tap before the factory amp....and use those filters between the tap and the factory amp..hmmmm.  Man...budjets suck.

Thanks again for the advise NyxBass!

Ack....My factory speakers read 400 ohms?!  I know the meter is good...My subs read 3.5 ohms...Is this some factory thing so I would have to replace the whole system? I'm new to this audio thing....and I'm getting more confused every day

thx

Hi Jim, disconnect the speaker leads going to the speaker before measuring. If you did this when you measured and still came up with a 400 ohm reading, then it sounds like you're not measuring the speaker and are most likely measuring the input of the amplifier. Let us know what you find.

Without using an active crossover on your amplifier, the amplifier will continue to produce frequencies above the desired cutoff frequency for your sub. You can still use F-Mods as NyxBass suggested or any other active crossover without effecting your rear speakers. To solve your problem with your rear speakers you can cap them off to only allow frequencies above 100Hz to pass. The value of the capacitors will depend on the nominal impedance of your rear speakers.
