Default Suggestions For Sound System in STi

My knowledge of soundsystems and stereos and stuff isnt so great, but what do you guys recommend for a deck unit, speakers, and tweeters?

I checked out some speakers such as Infinity, Pioneer, Polk, and Sony? which do you guys recommend from experience? Also i like how the Pioneer Deck has a gunmetal look to it.... are they any good?

>I have about 1,000 to spend on a system, i dont want to get into amps and subs yet... just a deck, speakers and tweeters.


Thx.

Personally I went with an Alpine CDA-7897 deck, but I don't have any strong opinions on that. I see a lot of people choosing the CDA-9815 or the cheaper CDA-9813 units.

Try looking at the Focal speakers. I listened to quite a few brands and models (with no subs running) and really like the 165K's. About $700 for the pair at your local high-mark-up shop, $299 at onlinecarstereo or $272 (including shipping) at CBR Stereo. From comments heard on the net as well as my listening, the Focal PolyKevlars should be much better sounding than the brands you listed. A lot of people also like the Diamond Audio HEX series (the s600s specifically), and MB Quart has its fans. I also briefly looked at the Boston Acoustics line.

In my experience with home and theatre stereo, the speakers make a pretty audible difference, while things like amps and source units were typically subtle (for those that might argue, just pretend I said "relatively subtle" -- compared to speaker differences, CD player sound differences are basically nonexistant). Hence it is a good idea to invest a high proportion of the system cost into the speakers. In car audio, from my recent listing, the differences between speakers is far greater than I've heard from almost any home speakers -- pretty big frequency differences which are more than would be tolerated in any serious home system. Hence I'd say it is even more important to get good speakers. On the other hand, I suppose the car environment is so bad for sound that it doesn't matter as much as a home listening room.

Anyway, that is what I might look at for the fronts. I've heard a variety of opinions on the rears. I've decided to skip them for now, but some people think the extra fill really helps (others say it ruins the imaging, so take your pick of opinion). I had been contemplating the Focal 130CA 5.25" coax for the rear, but after listening to them decided that anything less than the PolyKevlar just would be taking away from the sound quality of the fronts. Maybe I'll shoehorn a set of the 136K's in later.

Don't forget about the EBay for this stuff. I got Alpine 9815, Jl-Audio XR650CSi for front and XR650CXi for rears for less that 750 shipped. Installed it all myself for less than 800.

Loudspeakers are also a matter of personal preference. Some people like a relatively bright, clear sound, others prefer speakers with more powerful bass. There are speakers that are just plain bad (like the ones you normally get standard with cars), but once you get to a certain quality level, it's worth test listening, and finding out what fits your taste.

I absolutely agree with WRX_Mundi, speakers are mostly the weakest link in stereos, and choosing the right ones will make a dramatic difference.

I haven't bought a good car stereo in a long time, so I can't give very specific recommendations. I made very good experiences with Sony headunits, but that was years ago. They actually used to make a lot of the units for other manufacturers, I'm not sure if that's still the case. Many of the well known car stereo brands were just Sonys sold for a higher price.

Thank you guys very much, seems you know what your talking about which is good... ive never heard of those FOCAL speakers before.

Ill look into the FOCAL speakers... sounds interesting... what do you guys think about this deck unit i might get from Panasonic:


http://catalog2.panasonic.com/webapp...odel=CQ-DF903U

Any experiences with Pansonic deck units?

I'm curious how many people are going for compressed audio / mp3 / wmv player systems and how many are sticking with CD Changers?

Here is my initial list of most wanted car audio components. I went through and did an all Alpine setup just because that is what I was looking at. I think the HU should look very nice with the silver trim it has.

CD/MP3 Head Unit - Alpine CDA-9807 - $279.99
6disc Changer - Alpine CHA-S634 - $299.99
5ch Amplifier - Alpine MRV-F450 - $499.99
6.5" Components - Alpine Type-R SPR-176A - $249.99
10" Subwoofer - Alpine SWR-1041D - $179.99

And one other thing to consider is the cost. I pulled the prices above from Crutchfield. However I was looking on eBay and everything is for sale 'brand new in box' for almost half as much.

on ebay, I found a Hard Drive called the Neo Car which can come with a 20, 40, 80, or 120 gig hard drive to store mp3s. Any one with any experience?

I put Boston Acoustics Pro Series in my STi, and they sound excellent. (Mind you I have a 650 watt Kenwood amp powering them). In my opinion, they compare with the Bose system in my Porsche Cayenne. I installed the Kenwood Music Keg with a 20 gig cartridge type storage media. I personally would not want a hard drive (like in your computer) in the trunk of my car, bumps and heat could kill it! I still have the stock Suby 6 disc changer, but that POS is coming out next week in place of a Kenwood self-hiding deck.

CD\MP3 players

This is just the basic industry standard ones. As for all of the hacked up PC MP3 players for your car; those are all strung out all over the web.

Phatbox. Nice thing about this one is it plugs into some Factory decks... looks like a CD changer to them. For some cars, this is the way to go if you want to keep your factory deck and steering wheel audio controls.

Neocar. Not familiar with it. Looks like it can work with some factory head units as well:
http://www.ssiamerica.com/products/neo35/

Rio Empeg. Looks like you can't get them anymore. Future uncertain. This unit ran Linux on an ARM cpu, holding up to 2 drives worth of MP3s.

I'm wondering what size speakers fit the doors best? What's the way to go if you want to get reasonable (not huge) bass without using up trunk area with a sub?

i have heard of people saying compressed format are big no no s for high end speakers/amp combos.. because you can heard all the flaws in the music

is that true?

Well it depends on the bit rate of the music. Most qaulity mp3's and wmvs are at a high enough bit rate that is superior to cd qaulity and are great for high end setups. But if you have a low bit rate song then yea you aren't going to be able to really enjoy the music because it's lack of depth.

If you're interested on hearing more info on compressed audio, read on...

A lot of people have bashed MP3 and other compressed formats without knowing much about them. They've based their low opinion on a few low-quality MP3s downloaded off the web.

This is comparable to saying all Imprezza's are low powered econo-boxes after driving a 2.5 TS and having never driven an STi.

Just to give you an idea of the range of compressed audio, at the low-end you've got low-bitrate MP3s, and at the high-end you've got DVD audio, which is considered to be better than standard CD audio.

The factors affecting the quality of MP3's specifically are the bitrate and the codec (encoding algorithm) used. Early on the codecs were very poor in dealing with high-frequency audio so they just tossed out everything above 16khz.

Now, codecs support much higher bitrates, as well as variable bitrates. Variable bitrate codecs (VBR) can use more data when they need it, and they turn down the amount of data when it's not needed (ie silence, voice or instrument solo). The latest codecs also support frequencies up to 22khz and beyond, and they reproduce sound with much lower error rates. Accuracy is measured by comparing a codec's output with the original. Many codec's have variances lower than the audio equipment most people use, and basically can't be distinguished from a CD.


If you're downloading stuff off the web, some of it may be good, some of it bad. If you're converting your own CD collection to a compressed format (mp3, wmv, ogg vorbis) you can get quality that you won't be able to distinguish from the original CDs. A car audio environment is typically noisy and has relatively poor accoustics anyways.

for Ripping my Own CDs i use Lame 320 - 192 VBR

i used to think it is at least comparable to CD quality.

but there are other format that doens't affect quality at all..

such as APE?


but i haven't heard them on any high end system.. (no $ ^_^)

just wanna know if anyone has had any experience with them?

thx

for my own setup i prolly will use Diamond Audio S6.0 Mx3 Hex 3 way.

maybe Capco amps

I use the same codec and quality for my collection as well. I had originally ripped my collection using Fraunhoffer 128k, and later realized it was crap after listening to some of the artifacts the codec had added to some songs. I think HQ VBR is much, much better.

I've started to collect some APE stuff as well. Not sure if any portable players can play it though. Problem is, instead of the 10:1 or 8:1 compression you get with various MP3 formats, you get 3:1. So you can't hold as many songs in this format, depending on your disk space. But now that 300GB drives are shipping, maybe it's not so much an issue.

I keep waiting to see what will happen with Ogg Vorbis but doesn't seem to be much happening.

I have seen though that WMA support is spreading to several of the portable MP3 and DVD players.

There are apps out there to compare a samples, and measure the error, if you want a numerical comparison.

I think the best bang for buck to get accurate sound is with headphones. Speaking for myself, I've had the best luck hearing codec artifacts by using headphones. There are certain types of sound that really stress test a codec well, particularly ones that span the entire frequency range, top to bottom, simultaneously. This is difficult for a codec, because it doesn't know on which part of the spectrum to use the limited number of bits that it has.

I've found testing with sounds like this from my CDs I was able to point out problems that some codecs had and others did not, using good quality headphones. This is just one example... there are other tests too.
