I have just installed a pair of MB Quart components for the front door of my coupe. I have done mounting the speakers and wiring the speakers seems to play fine. but i have one doubt that since im still using stock bose amp, do i connect the cross over to the green and red wire that was connected to the stock bose lower speaker on the door. And the main question is that i have connect the green wire as Positive and red wire as negative? thats what i did and it seems to work but i just want to make sure that i did not mix up the wires.

 

Yes, I think you've got it right. I just did it in a similar way - but I used the tweeter connection and not the woofer (they are one in the same). I left the lower plug disconnected.

Nice of them to use green and red, eh? If you look at the stock tweeter plug (which I reused, it is black and white - with black being ground and connecting to the red on the door wiring). When I was doing it, I checked in the service manual and its ok (and sounds good).

 

get another amp

 

so u connected to the tweeter connection and not the woofer? is there a difference? i connected to the woofer connection....but i am experiencing some noise like hiss sound when the stereo is off...

another question is that where did u mount the cross over? i have glued to the plastic door panel right under the arm rest.

 

There should be no new hiss sound - this problem has only been reported with aftermarket amp connections.

It doesn't matter whether you use the tweeter or woofer connection.

The crossover can go anywhere it'll fit... I attached it to the metal part towards the front in between the tweeter and woofer location (upper front aspect) - plenty of room there.

 

is it a bad sign with the new hiss sound?? should i look into it or it doesnt hurt?
and there is another person said that there is a stock cross over that we should tap the wires before that...i dun think is true correct me if im wrong...

There is no crossover, other than the small capacitor attached to the tweeter which filters out low frequencies (well below like 8 kHz). The woofer receives the full spectrum. No worries... If the hiss doesn't bother you, then I wouldn't worry about it. I don't understand why you've got it though.
