I had to unplug the noise canceling mics. One is located in the dome light fixture in the ceiling up front. You have to take the fixture down and you will see a little black box. The second is located on the back dash. You have to let the back seat down and pop the dash cover and the little box is setting right in the middle of the dash between the rear speakers. Pretty easy to get to both of them...and the feedback noise is gone.

INSTALL A HIGH QUALITY CONVERTER IF U ARE USING THE FACTORY RADIO. CHECK YOUR GROUND CONNECTION, INSTALL A BETTER SET OF RCA JACKS. THE NOISE IS BEING PICKED UP THROUGH THE RCA CABLES, RUN THEM ON THE OPPOSITE SIDE OF THE CAR. U CAN ALSO PICK THE NOISE UP FROM THE FUEL PUMP, BUT BETTER RCA WILL FIX MOST PROBLEMS

What kind of wire do I need to install Infinity reference series 605cs with a JL Audio 10" sub and a Alpine Flex 2 amp? Can I use my factory head unit?


You can use the factory speaker wiring for the Infinity speakers you should purchase a amp kit which will give you everything to install the amp. See site below

Well that all depends on the current audio system you have now is it just a basic or a premium factory system with a factory amp. Honestly you would get a better and cleaner sound if you change the factory head unit to a after market one which has preamp feeds and the higher the preout volt the better. Just make sure it is compatible with the amp volts input (Example 4v to 250mv) If you use the factory headunit you would have to by a high to preout adapter it connects to the exsiting radios speaker leads, but like I said before change the head unit you won't be sorry. Do not forget if you change the radio you need a radio install kit and the wiring harrness which converts the two radio plugs so you don't cut them so down the road you can remove the after market radio and just replug the factory right back in.

Try to install 3 12w3d6 subwoofers connecting 3 sub together to put them in box


You need to wire them according to the limitations of your amp you can pull a 1 ohm overall load just by connecting all of your coils in parallel- or you can get an overall load of 4 ohms by wiring each sub individually in a series configuration which will yield a 12 ohm load per sub -and then wire the 3 sets in parallel which will bring your ohms back down to 4. You can do a lot with that many coils it depends on your amp really-ideally a 1 ohm stable class d mono amp that is 1000-1500 watts rms would knock the **** outta those things JL is the good stuff.

I want a great sound system in my van. what do you advice and how much will it cost?


go pioneer, best bang for your buck. you'll prolly wanna buy a headunit, 4 componant speakers, one 10in sub, one 4 channel 500watt amp, sub box, and wiring. pricing depends on how high end you go i recommend:

Headunit: Pioneer, price depends on model, a nice one=120-150, you'll prolly need a dash kit so it'll fit your van, wal-mart like 15$, and also a wiring harness to plug into your factory wires, again wal-mart like 7$

Speakers: depends on the van, buy speakers that are the same size as your factory so changing them'll be easy. Buy pioneer, that'll handle about 60-70 watts RMS. you'll prolly pay about 120 for a pair.

Sub:Pioneer ts-w257d4 60$

Amp: Alpine mrp-f550 210$

Sub Box: Scosche, available at wal-mart, 30$

Wiring Kit: Schosche, Also at wal-mart, 30-35$

Pricing on sub, amp, headunit, and speakers comes from sonicelectronix.com, another good website is onlinecarstereo.com So a grand total for materials is gonna be 775-850 after shipping on online bought stuff.(onlinecarstereo.com has free shipping on orders over 100$)
If you pay for installation then you're prolly lookin another 150-250 bucks. it ain't cheap but your system will sound KICK ***!!!

Can i connect the amplifier and subwoofer to the built ford fiesta radio


If your amp has rca jack inputs only you will need in-line filters to reduce the stock stereo speaker outputs down to less than 3 watts. If your amp has high power inputs you can use those. If your amp does not have a built-in crossover then you will need to install a low-pass crossover or filter before the amp so the only the bass comes thru or the sub woofer will have major distortion. Another problem is the amplifier needs a turn-on signal for the blue wire and most factory radios do not have one. That means you will have to tie that wire into the switched 12v wire from the vehicle so the amp comes on when the key is switched on. It can be done be done but I don't think you will be very impressed with the sub due to most factory stereos have a limited bass range. Most aftermarket head units have built-in crossovers and sub outputs. They also produce much better sound than the factory unit. So in other words yes you can.

'04 Nissan Sentra S factory installed subwoofer wiring diagram


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.

You can use the factory wiring but, it would sound better with an after market stereo and RCA plugs. You should look into some amp wiring kits for your vehicle. More than likely you will nee an amp to push a set of subs.
