i dont know to much about audio, but im deciding to install my setup myself. i bought a set of memphis msync6 compnents and i want to power them and my jl 10w3v3 with my jl 300/4 amp. i pulled a diagram off of the jl website, but where im confused is that the factory wiring doesnt get used. if it doesnt get used then what do i do with the wires?

 

You could not use them and keep them where they are in case you plan to get rid of the car its easily put back to stock, or... pull em out

 

that JL 300/4 will only power your components, not the subwoofer added.

 

You need to figure out where your amps are going, then run new wires to the speaker locations from the amp. Just leave the factory wiring disconnected and tied up out of the way.

 

well he should be able to run the speakers and the sub with the 4 channel if he is only putting the amp on the front speakers...i know most 4 channel amps have the ablity to run subs on the rear channels

 

not this amp. I have the same amp. He already said he has a w3. He would need 300 rms watts for it to sound pretty good. would be even worse if the ohms don't match up as well.

 

i think it would sound alright with 150 watts on it....i would not perform to its potential but i dont think it would be bad...but that is my .02..i have never used any jl equipment....and yeah if his ohm load isnt right it wouldnt be that great

 

i should be alright if i am only powering the components and just one jl w3? jl calls for optimum performance at 150 watts and that is all i really want to push out of the sub. ive lost most of my hearing as it is anyways, im not worried about full potential. and i will be pushing at 4 ohms.
