I want to put a jl audio 6 channel amp in my dodge magnum on all speakers. I have six speakers in the car. The speakers are rated at four ohms and the amp quotes that the max stereo watts is in two ohms. The only way to get to ohms is to buy some two ohm speakers, put two four ohm speakers in parallel. My question is, has any one ever put a resistor in a audio system. I was thing about putting a four ohm resistor in parrallel with each speaker to get stereo max watts. Do you think this will work.

DO NOT use resistors in your speaker wiring. This does absolutely nothing as the extra wattage you are going to get will be sucked up by the resistor anyways and not go to the speakers.(Just learned this myself when talking to a fellow enthusiast as I have actually done this 2x 4ohm subs and 1x 2ohm resistor to run the amp at 1ohm) You will need to provide a lot more info about what you are doing before anyone can help. Here are the questions that need to be answered.
1) Factory head unit? If not, brand and model #
2) Factory speakers? If not, brand and model #, installed in factory locations?
3) Model # of amp
4) Do you already own this amp?
5) Do you ever plan to add subs?
6) Will you ever expand system to add more amps, speakers, EQ, etc?
Once you provide these answers it will be a piece of cake to help you out. If it is the G6600 model JL amp you will NEVER hear the difference between 4 and 2ohms as it is only 20watts less at 4ohms than at 2. Will be waiting to hear the answers.

I did not look up the specs for your amplifier, but say for instance it is rated at 50 per into 4 and as stated above 70 per into 2. If the 4 ohm speaker was 4 ohms at all frequencies, it would share the power with the resistor. 70/2=35. 15 watts below what you would have had without the resistor. Since the speaker is well above 4 ohms at a lot of frequencies, say the speaker is 8 ohms at a certain frequency, the speaker will see 33% of the power at that frequency. 70X.33= 23 watts. The resistor will always be wasting power that the speakers could be using.
This is my plans. I am planning on putting a pioneer avh-p5000dvd head unit, two jl audio amps.(a6450) and a (250/1v2). I am going to put the six channel amp on 6*9 in back, 6 1/2 components in doors, and i think 3 1/2 in the dash all jl audio. Then put the other amp on two jl sub, probaly some w3's. i know how to wire the subs but i was trying to get max watt out of the other speakers. if the other couple of watts wouldn't matter i probaly will wire them just straight stereo. I haven't ever used resistors in a system, but i was asking to see if somebody else has and what was the results. if anybody can give me some tips please let me know.

Just wire them, as you say, straight stereo to the amp. One speaker to one channel. That's the best tip you can get.
