Chris O's 2009 Nissan Maxima

I've been with Crutchfield since 1999, where I began as one our advisors, helping our customers choose new gear. After a couple of years, I moved to the writing team where I spent a decade researching new products and getting hands on with car stereos, amplifiers, speakers, and subs. Yeah, I've been doing this for a while.

For the past few years, I've been the managing editor of Crutchfield's Car A/V web article content. I couldn't ask for a better job — we get to play with car audio gear every day! I'm a Virginia native from the heart of the Blue Ridge Mountains. Outside of work, I love listening to music, playing board games, and installing new audio systems for my friends.

Installation Description

My goal was to have the best sounding system while retaining the factory interior look, and keeping the factory head unit because it contains a six-disc changer and is attached to a large display screen.

I chose to have all the equipment professionally installed, which turned out to be a wise decision because of the complexity of the installation. After removing the door panels it was discovered that the factory system had a very complicated configuration, and all the factory speaker wiring was the same color. After sorting the wiring, the installer connected the sound processor to the head unit, which then connected to the external components.

The factory setup included front and rear door speakers, as well as two rear deck woofers. I replaced the door speakers, and also put full range speakers in place of the woofers in the deck. The subs and amps were installed in the trunk. Four channels of the six channel amp were bridged to power the front door speakers, the remaining two channels power the rear deck speakers, and the head unit powers the rear door speakers.

The two amps were drilled into custom wooden risers, and the sub box was screwed into the trunk carpet. The hybrid capacitor was hidden under the trunk carpet in a compartment near the bumper. By keeping the factory head unit, I have full steering wheel controls and an OEM look with much improved sound.

Q&A Section

Why did you decide to upgrade your A/V system?

I wanted to be able to listen to my music as loud as my ears can stand it without distortion.

What's the first thing you show people about your installation?

The subs and amps in the trunk.

Why did you choose these products?

I chose the JL Audio hardware because of the reliability and quality, the AudioControl sound processor for the functionality, and the subs were from a previous installation.

What was the most difficult part of the installation?

The most difficut part of the installation by far was identifying the factory speaker wire. The head unit powered the front and rear door factory speakers, a separate amp powered the factory woofers, and all the speaker wire was the same color.

What plans, if any, do you have for future upgrades?

I'm very happy with the sound and don't plan on making any more upgrades in that department, but I would like to add HID headlights in the future.

    dose my 2000 Nissan maxima with bose system have 2 rear deck speakers or a subwoofer am confused or woofer and 2 speakers ?????

    Anthony, your 2000 Maxima with the Bose system has two front door speakers, two rear door speakers, and a powered subwoofer in the rear deck. If you'd like to find replacements, enter your vehicle information in our vehicle selector to confirm which speakers will fit. You'll find that there will be a range of sizes that fit. Some of those sizes will require modification to the factory locations to fit, but we have a wide selection that won't.

    Question. I have a 2014 Maxima (no nav, no bose) and would like to swap speakers. It seems that none of the JL Audio speakers here fit the vehicle. I swapped "my car" to a 2009 Maxima and still none of these fit. Any comment?

    J, the space in the Maxima's doors is very tight, and very few speakers will be an easy drop-in replacement. Chris had his speakers installed by a professional, someone who wasn't afraid to alter the door's metal framework and fabricated spacers in order to make room for those speakers. In fact, the space is so tight, that your best bet is to consider 5-1/4" speakers. But even then, your choices are limited.

    I have a 2010 maxima what is the size of the center speaker in the dash

  • Alexander Hrabe from Crutchfield

    Reginald, your Maxima's center speaker is a non-standard size, about 3" in diameter, with a mounting depth of 1.461". If you replace it, you'll need to fabricate a bracket for it to fit and there is no wiring harness available.

    I have a 2010 maxima with Bose, no navigation. My speaker selections when I do (what fits my car) shows 5.25, 6x9's, and 6.5 speakers selections for the doors and rear dash. Is their a subwoofer in the rear dash and would everything still need altering with the speaker sizes shown?

  • Alexander Hrabe from Crutchfield

    Posted on 4/11/2016

    Edward, the 6"x9" speakers shown will fit in your front door openings as well as the rear deck without the need for speaker brackets. The rear deck speakers receive bass frequencies only from the factory amp, so those are your subs. The front doors, the rear doors, and the rear deck will accept the 6-1/2" and 5-1/4" speakers shown by using speaker brackets. Bose systems also feature a roughly 3" speaker in the center dash, and there are locations in the dash corners for tweeters if you opt for a component set. If you have any other questions, just give us a call and an advisor will help you find the right speakers for your vehicle.

    How did you get your power wire through the firewall?

    I have a 2013 maxima without the tech package and I need to know what double din kit and radio would be the best fit for my car. To use navigation and Bluetooth audio from my phone. And the dash kit to keep it looking clean and neat. And can I also still use the screen that's in the car for my backup camera.

    Robert, an advisor will contact you soon to help you find the right package for your Maxima. In the meantime, you can use our vehicle selector to confirm which stereos fit your car and get some info on what else is needed for the installation.
