it helps for listening to your music with lower volume
better and clearer sound quality

Isit expensive?

depends

Estimate for a vios?

what you want to soundproof?
what material?
whole car?
hehe

Saw alot of people use Dynamat

Hmmm, previously i got my car side door speaker and rear speaker when it is too loud the whole dashboard vibrate can a sound proof prevent that?

yes get a dashboard treatment to prevent that might be below rm 400 or more
i just soundproof my door cause door panel vibrate when music is loud lol\
now no more

opposite rather, because speakers vibrate/reverberation, and you need sound proofing to reduce/remove it

ya true but also make car more quieter for more pleasant music listening without road noise

Dynamat is the best soundproof, made in USA. However it is very expensive, you can go for local material and brand, cheaper by half. If you keen for Dynamat, I sell Dynamat sheets, no installation provided, estimated whole car for normal sedan(Doors + Floor + Roof + Boot and Engine Bonnet) you will need around 15-20 sheets.

You'll need to have a budget in mind when come to soundproofing.

Deal with your source of noise instead of follow whatever people say.

It seems that your car doors rattle when music go loud, so you may consider door dampening.

There are different way of dealing with door soundproofing, basically all you need to do it to dampen and then do sound insulation. (Of course, depend on your budget too~)

I would suggest you to do the front door soundproof first. At least you can feel the effect immediately.

There are so many brands out there for you to choose from. Budget counts and definitely applying it the correct way counts too.

If you are hesitant on DIY, then get some skilled installer to do it.

Do take note as well that, some unheard of brand out there are basically just a waste of money. Seen it, tested it and already throw away.

Agree with you, while trying to save budget, go around ask opinions from different experts, and get a reputable brand. I was once a victim by getting cheap china made soundproof, Rm30-Rm40 per piece, unable to stick well, not long lasting, and the effect is disappointing. Have to change again in the end, waste of money.

i highly emphasize on this

ya this is so true
my car already quiet so i just dampen the doors to kill the rattles
and btw i wanna ask something,upgrading rear speakers is it really a waste?

if you're going to satisfy rear passengers, or even have external SQ etc (trip to EMMA really taught me new stuff haha) then no

if only for yourself, huge waste.

how much is a domination speaker cost?

I disagree with Quazacolt.

Having rear speakers is a personal preference. I kinda like sound surrounding me from back and front like that, nevermind the staging. So personally if you ask me it's not a waste of money.

It's a personal preference.

You got the money then go for it. If limited then optimize front speakers only. Purists will say front only, but i'm not a purist and I just like the way it sounds so it's up to you

upmixing can be a b**** to deal with though. do remember that a huge majority (what, 99% or more?) of music/songs etc are in stereo, so that means whatever surround you're going to have is upmixed. (i speak from experience having a creative G500 5.1 speaker set for my pc )

if you're keeping front/rear L/R stereo kinda "surround", then it'll be just unnecessary push on the SPL which not only affects the sound staging (assuming one doesn't mind in the first place) but also affects the tonality/imaging and even separation of your audio reproduction.

it makes much more sense to focus the money on the front where you - the driver is at

Hi ezmeer 94, sp is really nice. The sound of ur ice will be more focus. I can get u dynamat double layers 4 door at $700. For your info, i m addicted until to do the sp to roof, trunk & fender. No time to do the floor yet. Is good till the door will become solid and the sound when u closing door is good.

Yeah, for true SQ, focus on front speakers will do. Invest a really really good front vocal speakers. As for me, I still install after-market rear speakers for the comfort of rear passengers, coz i do alot of fetching. Secondly is I want the surround effect when watching DVD.

I guess for SQ with front and rear speakers, time correction can correct the effect of the problem arise of upmixing, correct me if i am wrong. (My personal opinion)
