g37 stereo upgrade help
 

2009 G37 coupe (base)

i have minimal knowledge on car stereo systems so please go easy on me

base system is garbage and i'm looking for something a little nicer whilst on a low budget. With my scarce knowledge i've picked out these things:

Amazon.com: Pyramid TW44 1-Inch Tweeter: Car Electronics

Are these okay choices? What am i missing? Do I need a subwoofer in the trunk to get descent bass?

I would like a system that could play something like led zeppelin clearly, as well as be able to put out some bass during rap songs

THANK YOU ALL IN ADVANCE I REALLY APPRECIATE THE HELP

Please don't replace your stock system with those garbage speakers. They will most likely sound worse and will most likely blow within a few weeks. Then you'll be out like a hundred bucks.

Save your money and get decent speakers down the road if you still want better sound.

Well I can probably spend up to $500/$600 for now and i'm wondering what is the best setup for the money that a beginner could learn to install. Any ideas?

Take it to a stereo shop and let the experts handle it. An Infiniti isn't a car a beginner should be "learning" on.

will $600 even get me anything at a stereo shop?

hell if i know. you need to do the research. call around. tallk to people in the shops.

most people on here don't replace their stereo systems. if anything, they just add some extra bass.

you seriously need to check with some of the shops in your area, because you won't know until you do.

the G is a very difficult and expensive car to do sound system modifications in. Your best bet will definitely be a shop, it will be tough to do much on that price range though. What exactly is bothering you about the stock system? Your best off fixing the most offending thing for now IMO.

A good amp and sub would be the minimum mod I would go with. The stock speakers actually sound decent with a good amp driving them. I can't see doing even that for under $1k though. I'd save and wait. You would be wasting your money and be disappointed with the sound you get from going cheap.

Door speaker replacement isn't to bad.
Get a decent set that is within your budget.
Infinity reference or Polk components are the best bet for budget installs.

Head unit replacement is almost impossible in this car.
If you can't get your set up to sound the way you want it to then you would need to add a a sound processor and/or an amp.
Adding a processor is more on the mid to upper end of install skills.

Thanks for all the input you guys, I tried calling around and $600 in car audio shop wont be able to get me really anything.

I'm looking for some better bass as well as less distortion.

With this, I was looking into replacing door speakers (6.5) with speakers and the rear deck speakers (6x9?)


-Would this setup produce descent bass? (I do not want a trunk sub)
-Would this be a good setup for the $?
-Would I need a new amp to go with these?

I have friends who have replaced/installed speakers so i'm confident that with help and a day in the garage I can get it finished

PLEASE DO NOT SUGGEST A STORE AS I'M GOING TO DO IT MYSELF

Thank you all for your patience and assistance

No. You'd probably get decent mid range though. For decent bass, you're probably going to need some sort of trunk sub and amp combination.

No. Save your money.

Most likely. The stock amp is set at a certain impedance as well as the speakers (8 or 16 ohms)...they're "matched". You start throwing 4 ohm speakers in the mix, and the stock amp won't last long. Especially since I'm getting the feeling you probably blast the volume.


If you're going to go against the suggestions in this thread and "learn" on your Infiniti, at least get a wiring diagram for the stereo. That may help, but it sounds like you've already made up your mind.

Good luck

If you have the non Bose radio, the amp is actually incorporated into the headunit. Because of that, there's not much you can do to really improve the quality, cause you can't get to the sound before the EQ'ing. Not sure offhand of the stock speaker size for base cars, but no matter what I'll bet money just doing speakers will help so little you probably will barely notice it. The best thing I could think of for that price range is get a line output converter behind the headunit, run RCA's to the trunk, and get a good amp to push the stock speakers. Set it up so that the headunit volume is never over half, because it does some funny things to the sound as you go louder that you can never get away from unless you get a processor. Also, is scrap the rear speakers. Spend your money on the front, thats what you hear most.

And no matter what you do, you cannot get much bass out of the door speakers. Nor do you want to, it will make everything sound muddy. If you want bass, you need some sort of subwoofer. Door speakers just aren't good for it

im in the same boat... 2008 non bose g37 coupe.... can anyone suggest good replacement speakers that would work with the factory radio?

Any speaker will work. If you want it to sound better though, speakers aren't the way to do it. I can almost guarantee it will sound worse if you just do speakers

I'm not sure about the non-Bose but the Bose speakers are 1 Ohm. As others have said in this thread, if you want SQ you're better off waiting and saving until you have enough to pay for it.

I guess Ive been extremely luck so far. It only took about four hours to run the 0/Ga wire to the trunk for the power feed. That alone took me over a day and a half in my Mustang. So far Ive found the G to be very logical and easy to work with. Having the complete shop manual with schematics and logic flow was a bonus as well. Id offer the opinion that if your halfway good with your hands; have some tools to work with and space to leave things torn apart; and some patience; the G isn't all that bad to work on.

Expensive? Definately if you break something. The interior parts for the older cars are a bit hard to find round here and the pristine ones are definately not cheap

Running the wire wasn't too bad, the molex at the doors requires lots of care though. But fabricating each speaker mount in the doors and tweeters in the sill takes some expirience too. There's just not an easy or cheap sloution, diy saves you money to spend on parts until you get in over your head and damage something. For good SQ I can't see adding a bass amp and sub, that will only make more thump. Components in the doors and a multi channel amp will head you in the right direction to start, remember the doors can hold 10 inch drivers. Sounds like for those without the Bose will need a processor to sum up the signal as well.

A sub can add plenty of SQ.
You dont need a huge sub and amp to fill in the low end. For most 500 watts rms is good for a daily driver.

The doors will hold 10" drivers but the depth of the door is the issue.

My 6.75" speakers barley fit in the doors even with 1" spacers.
The total depth of the door with a 1" spacer is around 3.75"-4"
Measure first to ensure fitment

Do you have an update on this?

How did it go?

I just read it now - but I find that I get the best sound when I use the inputs from my Android phone and drive it through my phone equalizer.

I know. It is cheezy, but the sound is a hundred times better.

Somewhat off topic
I would pay alot of money if someone would give me a touchscreen headend unit that will show and control my phone!
