'04 Nissan Sentra S factory installed subwoofer wiring diagram
I have what lools like an amplified sub woofer. This is factory installed. I can not find any wiring diagram for this subwoofer. I reciently had an Alpine receiver installed because the factory radio went belly up. The Dealer rather than fix or get a new factory radio gave me the Alpine from a trade in. (Much better radio anyway.) The factory installed subwoofer was never connected so I would like to connect it. Any thoughts? Geoffrey:
Re: '04 Nissan Sentra S factory installed subwoofer...
A FACTORY INSTALLED AMP/SUB WILL BE WIRED INTO THE VEHICLES FACTORY WIRING JUST AS ANY OTHER COMPONENT. YOU WOULD THINK THAT YOU WOULD FIND THICK POWER AND GROUND CABLES ALONG WITH RCA CONNECTIONS AS YOU FIND WITH MOST INSTALLS.NOT THE CASE HERE.YOU MUST FIND THE HARNESS THAT HAS THE POWER AND GROUND CONNECTIONS ALONG WITH THE INPUT WIRES FOR SOUND. YOU MUST OBTAIN A VEHICLE SPECIFIC WIRING DIAGRAM THAT HAS THE WIRING FOR THE SOUND SYSTEM PACKAGE THAT CAME WITH YOUR VEHICLE. YOU MUST THEN WIRE IN THE BLUE REMOTE TURN ON LEAD FROM YOUR UNIT TO TURN THE AMP AND SUB ON WITH YOUR RADIO AND NOT YOUR CAR BATTERY. YOU WILL ALSO NEED TO FEED SOUND TO THE AMP USING ONE OF THE REAR OUTPUTS FROM YOUR RADIO.

for me i advice to you, but sonny explode,den they have a fit speaker to all panel, and for the sub u want, their is a cheap speaker name TARGA, and amplifiers cheap also, V12 is the model.. if you are near in manila, i can help u to setup your sound, bec, im a sound technician.. just txt me if u wannt 09397527921.. im mark..
You can connect the two 6x9 speakers to the two individual left and right outputs of the car stereo.
Connect each of the left and right channel with the correct polarity . Now the Sub-woofer requires an amplifier to be connected separately and so you need to use the car stereo to be linked to a sub woofer amp which powers the sub woofer.
Check to determine if your sub woofers are DVC 4OHM or DVC 2OHM
If your sub woofers are DVC 4OHM then, from the positive (+) of the amplifier run your cable to the positive terminal of voice coil 1 on sub woofer 1 then continue to connect all the positive voice coils together on both sub woofers.
Do the same for the negative from amplifier to all the negative voice coils of both the sub woofers.
RECAP: all positives together on the positives and all the negatives together on the negatives.
This will give you a 1 OHM load to the amplifier making it deliver all its power but will also run hot. So if you are living in a hot climate take care.
Connect the negative on voice coil 1 to the positive of voice coil 2 on sub woofer 1
Do the same for subwoofer 2
now you should have a free negative and a free positive on each of the sub woofers. connect the free positives together and follow through to the positive on the amplifier. do the same for the free negatives sending them to the amplifiers negative.
This will give you a 4 OHM load to the amplifier. Not full power in this mode but the most stable working condition for your amplifier.
If your sub woofers are DVC 2 OHM then you only have one reasonable wiring solution.
Connect like solution 2.
This time because of the DVC 2 OHM sub woofers you would have a 2 OHM load to the amplifier. This is also a stable load for the amplifier and does not generate to much heat and still deliver over 50% to 70% of the amplifiers power.
good luck and drop me a line if you still have doubts.
if ur amplifier have a pre out, then u can connect that to ur L/R input of ur sub woofer.
if not the only way is, connect ur amplifiers speaker output to sub woofers speaker input and then connect ur speaker to sub woofer speaker output terminal. remember don't inter change positive and negative wires.
if ur amplifier have speaker A,B connection then it is very easy. connect the speaker A to ur left and right speaker. then connect speaker B to ur sub woofer's left and right speaker input. be sure to make that speaker A and B switch is in on position. the power on both and check it. ( use good quality speaker cable to connect the sub woofer)
your sub woofer is designed to work , both at low level and high level input.
Your PSW815 has 2 ohm dual voice coils allowing you to better match the impedance to your amp. Each voice coil is 2 ohms. If you wire them in parallel (both +'s together and both -'s together and then to the amp terminals), the sub presents a 1 ohm load which is too low for most amps. Wiring the voice coils in series (one + to the other - and the remaining + and - to the amp terminals) results in a 4 ohm load.
This link shows the wiring diagram for both options. If you know for sure that your amp is 1 ohm stable, use Wiring Option #1. If the amp is not 1 ohm stable, use Wiring Option #2.
Get a hold of the woofer connector (I believe its brown) right by the whoofer and move it around/press it/disconnect and reconnect and check if the woofer comes on. There is a bad connection in the connector for the woofer itself. I have a 2001 GLE my self and that's what I found to be the problem with mine.
