How do you bypass the factory Bose sub-woofer and amp to ad an after market amp and sub in a 2000 Nissan Maxima SE?

Answer 1

I have a 2001 Nissan Maxima that has a Bose system. I found a way to bypass the need for a new amp and sub. Bose systems have little amps attached to each speaker including the sub on the parcel shelf. The cover of the sub comes off to expose screws hold the sub in place. In the trunk you can see three screws holding the black amp to rest of the speaker housing. What i did is disconnect that small black amp box( red and green wire if my memory serves) and let it dangle. Then I removed the rest of the speaker from the inside of the car. the amp believe it or not pumps ot approximately 100 watts. The Bose system in my 2001 Maxima was rated at approx. 1 Ohm. This rating is what the amp needs to read in order for any speaker to sound decent. This is why you can't just buy any 8" sub to replace in that spot. I needed to find a 1 Ohm 8" driver. Not easily done, however, i did find a dual voice coil 2 ohm speaker. Wired in parallel the speaker will read 1 ohm and will be safe to connect to the little black amp box dangling in the trunk. I did this approximately five years ago and have a sub on the back deck that is ten times what the Bose one was.The bass response is better the power handling is better and with some sound damping material there is no rattling anymore. The speaker I found at car domain. If you think you can do this I can give you a step by step to accomplish this in an afternoon!
