To cut or not to cut

[Ghostrider]

If you dun cut how is the sound going to come thru the rear leh ?

The kinda installation method is call Free Air Sub. Instead of using the box as an enclousure it uses the whole boot as its enclousure.

You have to cut a small part out from your rear parcel shelf...but dun need to cut too much. Watch out as some kuku I have seen cut almost the whole piece out...this will result in your rear begin very soft. Even you start blasting...your whole rear windscreen will flex as well.

Using a 10' or 12' depend on how big is your boot and what kinda sound you want. If you want those tight bass, go for the 10'X 2 setup...make sure you have anough juice (amp power) to drive it. Else your sub will bottom out due to lack of power on higher volume.

If you want to add ambience to the music only, 12' with min power is ok.

BTW...make sure the shop fabricate a piece of wood panel to support your subs...dun let them bolt directly to the metal...your metal sheet will not support that kinda weight.

Thanks Ghost. There are some owners who didnt cut, cos heart pain.
Also seen some Merc owners who didnt wanna cut also.
The sound certainly doesnt sound as good but there was still an effect. I did wonder also about how the sound is gonna travel thru such good insulation in bmws and benz..but apparently some owners really dont want any cutting.

Will prob go with a 12", and make sure the wood panel is done as mentioned by u.

Re: To cut or not to cut

Has anyone installed a free-air subwoofer , ie the kind not in the box but hanging jus like your rear speakers. One shop reco cuttin the metal board for a 10" sub, another say don't cut but use a 12". Opinions or share your experience pls...thanks.

Dun say Euro models...my friend's new RS200 Altezza also did not want to cut...the sub sounds so funny...I went to ask my installer about it...he told me "dun cut how to have sound coming out...all you can hear is so covered up and feel the sub vibrations only !!"

Like I said...dun need to cut a hugh hole...just small portion enough for the sound to travel thru is good enough.

Tip : Stay away when they cut....usually my install ask me to go drink kopi for 10mins while he cuts...you dun see not heart pain.

THanks Ghost...now seventh month ..anyway, spoke to two of the recommended ones. One say cut, one say better not cut. SO there... i guess its now down to individual judgement, as cliche as it may sound.

 

[Ghostrider]

I would like to know who said dun cut sia...wondering if they got some special installation or tuning technique that allows the sound waves to reach the cabin.

Care to PM me who is the installer who said that ? Just curious only....

Oh ya...all my good buddies coming out soon hor...everyone drive safely !! :laughlik: :laughlik:

You can try to contact Hock Hin at Alexandra Village. The shop is just infront of OG factory. Look for Ah Long. I saw they had this BMW HU there (those integrated kind) but I dunno if its for the e46 or not.

Or you can try to call Ah Hoe from Ang Kah Hoe Auto @ 62615262. He is running a scrap yard cum workshop. He might have the stuff that you need.

yeah should be me.
and yes of cse tuning very impt, but i prefer to tune it myself...
i may not be half as gd as them... but at least i noe wat i want..
coz i tried explaning the kind of mid-bass i want to many tuners..
but nobody seems to be able to replicate the sound i like...
so i just trial n error myself lor..
more fun this way too...

Nice car...i sat in your car haha...U moded your front panels for the speakers, didnt u? I went to LMV in yishun, in case u are interested in tuning. The boss invited me to sit in this car. I dunno much about tuning, i m pretty sure its darn good cos everything seems to come from the front, and i mean as if speakers were fixed at the windscreen facing you. Even the bass. absolutely brilliant. Heard he won some competition. And very helpful guy who's willin to share knowledge. So how's your car sound ? i wanted to ask the Chuan Sing to play but guess its not too nice without owner's permission.

Oh btw... u cut your door panel which many owners are reluctant to. I m eyeing the CDT HD62, a highly highly rated speakers within my budget, but i suspect i may need to cut the door panel as well. DO u face any prob, or should there be any prob cuttin the door panel ?

where's this LMV? what's the full name?
they do specifically tuning only?

CDT HD62 is a 6.5", rite? if so, i think have to modify ur door panel too..

DO u face any prob, or should there be any prob cuttin the door panel ?

hmmm.. problems? i dun think so...
but wat problems do u exactly mean?

 

[oneHeadlight]

As for moding the door panel, i think i m less reluctant than before. Need more space for the components to move. With proper soundproofing, think wun have water leak or vibration problem right ?
