Contour Enthusiasts Group Archives Forums Modifications Audio how to do this???

I have an aiwa 45x4 cd deck and 4 Infinty 5752cf's Installed... in my 99lx... I also have a 120 watt 2way amp. Is it possible to make this amp power all 4 of my speakers for some added punch?????

I am assuming this 2-channel amp is 2-ohm stable. If it is, you can run all 4 speakers, but you may be over powering them, since when you go from 4 to 2 ohms your power usually jumps up quite a bit.
However, to do this, run channel 1 down the driver's side. + from amp to + on speaker 1. + on speaker 1 to + on speaker 2.
Same on negative.

Use channel 2 for the other side. That will give you a 2 ohm load.

I am not responsible if you blow your speakers.

Sure, you can run all four speakers off of that amp. However, there are some advantages and disadvantages to doing so....
1)Amp will over heat easier(minor problem)
2)Amp must be 2 ohm stable
3)Power of the amplifier will double because there is less impedence(good when considering power)
4) SOund quality may decrease due to running the speakers at 2 ohms(minor problem in most cases)
5) YOu will loose the ability to fade between the rear and front speakers...and will loose all front/back sound dimension coming from surround sound(minor problem).
How to:
1)run the front left and rear left speaker wires in to the left channel. There will be 2 neg wires running into the screw terminal. There will be 2 pos wires running into the pos screw terminal.
2)repeat with right side
-pretty simple

Some people might just recomend powering the fronts off your 2 channel amp and running the rear speakers off your deck. That is what I did, and it worked the best for me. Its up to you though

i thought this was a pretty helpful thread.
just curious though, any of you guys have any suggestions for how to estimate power per speaker at 2 ohms from a 2 channel setup?

it depends on what it puts out at 4 ohms :p

coo tthnx for the reply im gonna hold off on this and prob just hook up my 8" kenwwod sub i didnt know all the problems that could cause and its a real pos amp also

You don't have to run in parallel, you can run in series.
This will make your load 8 ohms instead of 4.
Your amp can run this just fine with no side effects.
Run the + of the amp to the + of the front speaker,
then the - of the front speaker to the + of the rear speaker,
then the - of the rear speaker to the - of the amp.
Downsides to this are;
1) Only half the power getting to each speaker,
2) no fade control,
3) SQ isn't that great (Still better than stock sound though).
