Am I Downgrading My Sound>?

[crystos]

So i'm thinking if swapping out the already good speakers for hopefully something better. I have no idea what the wattage of the factory speakers are. From this site I have learnt the size of the front and rear. Anyway take a look below at what I am thinking of using.

or

and MAYBE

I'm sorry if this is a stupid thread. But i would like a lil help. If anyone cares to share their audio set up. And if you also know the wattage of the factory speakers.

you should try read more on G35driver.com in Audio section.

There are alot of people happy with just changing out the stock speakers to infinity one with 4 ohm. As our stock speakers is taking in 4 ohm instead 2 ohm on most aftermarket speakers.

your Polk Audio DB651 seems ok for the front, but please read more on the site i gave you to confirm. Btw is yours a Bose or not?

just curious, what's the reason most aftermarket chooses 2ohm ? are less resistance result to more powerful sound ?

what would happen if putting 2ohm speaker system on a factory's amp that feeds to oem 4ohm speakers? will it overload or underload?

well my car was bought used and it didn have the factory system in it. It has like an after market cd player... it has the tv screen tho. Should I take a picture? Thanx anyway I'll check the g35 site

All i know is that the lower the Ohm (2ohm or 1 Ohm) will create a more powerful sound, but less clarity hence the subwoofer. Therefore the Higher the Ohm are (4ohm or 8 ohm) will have much more clarity. Usually the 6.5" drive is to create a good mid bass therefore the 2 ohm is usefull for it, as the treble is created from the component tweeter.

I'm not 100% an audiophile, but i think that's what it is from what i learned. Please correct me if i'm wrong.

Home audio is 8Ohm, Generally car audio speakers are 4Ohm, I don't know where you guys got the idea it's 2Ohm.

Some subs, in particular dual voice coils, are 2ohm so can be wired in series to make 4 Ohm or wired parallel to make 1Ohm.

There are benefits and drawbacks for each, lower Ohmage draws more power output from the amplifier if the amp is capable of running lower ohmage. The downside is sound quality is reduced. Some would say that is not so crucial at lower frequencies BUT I certainly wouldn't be going less than 4ohm on your component ( front) speakers.

P.S. The speakers you've linked to are coax. In laymans terms the tweeter is mounted WITH the midbass driver. You want a component set where the midbass and tweeter are separate items. If the 250GT is the same as the 350GT then the factory locations are Midbass in the door and tweeter in the sail panel (behind the door mirror).

P.P.S. and for gods sake stay away from anything labelled BOSS !!!!!!!!!

thanx mosoto. Now I just have to work up the nerve to dismantle half the dash to get install my aftermarket stereo.

if its bose audio they will be 2ohm or less. bose did this to get more power (figuratively) from their amplifiers. some of them are 1 ohm.

[mosoto]

LOL even more reason to upgrade I don't have factory speakers so can't pass judgement on them but at 1ohm the sound quality would have to suffer immensely.

I'd normally assume the midbass & tweeters have HP/LP caps and are wired in series to present a 4ohm load to the amp, If not then the factory amp is an impressive little kit to be able to load down to 1ohm

for what it is the average punter is happy. for the SQ nuts it sux. the doors are paralled with a cap on the tweeter. I have a spare amp here and have yet to take the top off it. its an all alloy item though the size of a VERY thick book.

there is a removal guide for the radio posted in the audio section of this forum.
