Hi all.
Thinking of upgrading my stereo in our new (2nd hand) car - only has AM radio with a 1" speaker part of the radio unit!

Anyway, i was worndering how hard it is to install a stereo unit and speakers.
I have a good 'basic' knowledge of electronics etc but should i go to a Pro? and if so - anyone no how much they cost (for a 4 speaker installation and a stereo unit)

I always install my own,And everytime i'm halfway through im kicking myself for not get it done properly, and when i'm finished i kick myself twice.

Although having said that,The one time i did pay to get it done i was mucked around for days,finaly marched down to the "fitters" to see what the hell was goin on.....and they had sent the wagon elsewhere because they couldn't do it.

When i did find where it was sent they guys there informed me it had been dumped on them with the entire dash removed and all the cableing in a huge mess.......They were fair spewin, I was spewin,And the original shop tried to bill me $250 more then what the guys who fitted it charged them.

No wonder i have a temper.

If you haven't already bought the new unit, get prices from different shops then bargain for free installation.

A specialist car stereo shop should install it for nothing if you buy from them. You need to know your prices though or you could find that the price is inflated to allow for installation.

I found this site excellent for installation information.

ok,
thanks for that guys.
I was thinking of buying from Repco - but i just found this on TM:
http://www.trademe.co.nz/structure/0001-1245-0111-/auction-19633079.htm

It fits what i want (Mp3 player) plus at a good price - but i wouldn't have the faintest idea whats good and not!

no one no's of a good site where u can compare and read reviews on head units do they? All the sites i've found are commercial ones.

And a few Q's.
I see some that state they play MP3, then some others say MP3/WMA.
So will that mean that the ones that just say MP3 won't play WMA??

Do you need the Line out, or RCA out etc?

Whats Mosfet? (i see Mosfet 4x 50w)

Would yu recomend a cheaper unit and an Amp, or a more expensive unit w/o an amp?

And how are the sizes measured?
I just measured the grills in the car (for the speakers) and they were:
Front:
16x14cm - 6.5"x 5.5"
Rear:
21x14cm
8"x5.5"

Does this mean 16cm speakers are for teh front, andd 6x9" for the back?

cheers

Traditionally cars were designed for small speakers in the front and large for the back. But when you think about it, if you went to a concert, do you turn around with your back to the stage so that the sound comes from the back?

The logistics is to get the large speakers in the front but space is the problem, also speakers are normally positioned low (dash & door) so high frequency sounds are directly at your feet.

If at all possible get components for the front so that you have tweeters positioned high directed at your ears, the bass sound can direct anywhere.

I wouldnt go overboard for the back (you dont sit there and why spend heaps of money so that backseat passengers benefit more than the driver) just a decent brand 3 way would be enough.

Get a pro to instal, saves time and money if you screw it up.

odds are you will not have any factory speaker holes in the rear parcel shelf. DO NOT install speakers in the rear parcell shelf as you may fail a WOF !!. check with garage (and pro radio installers) first.

Well spoken tweak'e!

I know of someone who cut holes in the back parcel shelf (metal structure) and it effectively wrote the car off.

Cost of restoring the integral body structure for a WOF and having it certified was greater than the car value.

Makes for an expensive radio installation.

What are component speakers?
Are they a pack of normal and tweeters?
Can you just buy normal ones, and add on tweeters?

As for the rear panel shelf - may i ask what that is!!
There are covers/grills for speakers at the back - is this what you are talking about?
I'll go have alot whats under it

Possibly, but unfortunately we cannot dictate or guess what sellers call their products. But "component" would suggest that they are bare "speakers", and not "speakers in cabinets" which are also called "speakers" in the shop.

> Can you just buy normal ones, and add on tweeters?

Money will by (almost) anything.

> As for the rear panel shelf - may i ask what that is!!

Does your car have a back seat? Does it have a rear window? The rear shelf is the bit beween the back seat and the back window.

> There are covers/grills for speakers at the back - is this what you are talking about?

If they are on the back shelf, yes.

> I'll go have alot whats under it

Whatever you do, don't "enlarge" the holes or make new "holes" to accommodate the speakers (screw holes would be OK, not speaker holes) in the back metal shelf panel. That can damage the basic structure of the car, some rely on that panel for strength.

If you look at a normal speaker you will see that there is a centre speaker (sometimes 2) on top of the bass speaker. These speakers transmit both high and low sounds.

This (http://ecarhifi.firsteprocure.com/prod_images/avakit65_b.gif) is a pic of components (just a random pic I found via google).
The square box things are splitters. As the sound enters these (from the stereo or via the amp) then the splitter directs high sounds to tweeters and low sounds to the bass.

If money permits then I would definitely recommend these but you also have to consider installation of the tweeters as they can be tricky depending on the car.

just checked the back of the car - theres space for speakers at the rear - at the mo they have plastic coverings in the metal body - so thts all good.

As for the components speakers, if money allows - i'll get them (all starting to add up!)

I just have to pick the unit now, and its out of:

Sony CDXR3300 $280
The One off Trademe (link above) $230
Panasonic CQ-C1300W $250
Pioneer DEH-P4650MP $300
JVC KD-G455 $240

jeeze, now the fun begins!!

o, sorry, sony one is $320.

ok, i decided, is either the panasonic or the one from TM.
I got down to these 2 as the TM one is a good deal, and the PS one plays WMA also.
But i'm leaning to the TM, now just gotta decide if i need the Sub out version ($30 more)

as for speakers - sorry for all this, i'm just using it for reference for me!
Either:
1) Sony Component 200w XSG5160 $130 FROMT
Panasonic A6900N 3 way 180w $80 Rear

or
2) Sony XSGT6047 250watt 4 way (do u need 4 way for front speakers?) $100 FRONT
Sony XSGT6937X 3way 350watt $100

thoughts?

Might want to check these guys out... all the units you've mentioned available there, some up to $50 cheaper.

They also do good speaker prices. A mate just bought a Pioneer Head Unit and Speakers through them.

Hehe... well worth the look.

Self install shouldn't be tooo hard. I've done a few of them myself and had no significant problems.

Well, this is all different ain't it!!
How long has it been back up and running? Here i have been checking my Pressf1 link in my favourites (the addy with no www) everyday waiting to see when its back up and running, and thought i'd better check the direct link today - and whaddaya no!!

Anyway, i thought i'd let you guys all no what happened with the speakers/unit and installation since you all gave me alot of advice.

I went with Sony's Component Speakers for the front, and Sony 350watt 3ways for the rear.
And i went with the Sony CDX-F5500 Mp3 headunit.

I installed the speakers with relative ease - only trouble was (as i didn't have a manual for teh car - and after hrs of searching on the net) i didn't no which cable was positive and which negative!

When i put in the Stereo, i just took out the glove box, and i could reach up to the old one from there, and pushed it out.
I had to go to repco to get a wiring harness adapter, and i plugged it all in, turned the key - but nothing!
Spent about 3hrs checking the wiring and eveyrthing else, when i relised i had blown a fuse - a replacement now had teh sounds flowing!!

I noticed one speaker sounded really distorted, so i changed the + - wires around, and it sounds alot better, but i'm still not entirely sure if tehy're right.

So thanks a heap you guys
And merry Xmas, or Happy Festive season if thts more appropriate.
Cheers

The most important thing is what make and model of car do you have?
If its an old ****ter you might as well do it yourself the installation might cost more than the car.
