I feel that current stock unit and driver sound quality is not that bad after all. I own a J spec with a double din player (bought in promotion period last year). The mid-bass is quite alright to my opinion.
I just wonder why they installed the back driver on the door this time.?

It all depends on one's ears, some will say not worth it coz have higher expectation, but for some others good enough. I for one used to use big 12s from top US brands like JL Audio in the back either in free air or in a custom box powered by hundreds of watts of US amps, but now I just use a pair of China 10' underseat powered subs. Sure the under seats will not generate as much kick and as loud as the huge 12s but now I'm quite content already with those cheap underseats, enough to bring just a bit more live and punch to the music without breaking my bank. I guess as I get older my priorities and expectations already shifted as now I don't need to have a system that can shake my whole car! So in short just have listen yourself first if good enough or not, then only decide.

I have settled with Kenwood KSC-SW11
Yes. It doesn't give you that "boomboom" effect from a bass drum but more "thump" from a bass guitar
It does the job well in filling the low freq and I am satisfied with it as it doesn't take up my boot space

Underseat 8" subwoofer imho is not worth buying. Either you get a proper subwoofer at the back or just buy a proper midrange driver....

Recently installed MB Quart active sub, satisfied with it.

I just want a little kick on the bass, the box bass kinda too much for me.

Underseat subs... Well... I am using an underseat that is branded (I suppose) and i just installed a ported box subwoofer in myvi for half the price of the underseat sub alone (Exclude install, wiring and workmanship)... To be honest, it worked better, responded better and sounded better than the underseat and is richer in most ways... Now i finally understand why so many ICE sifus keep emphasising on using a boot sub rather than underseats... If you want very good bass in a car, go for the subs that fit in your boot... If you travel a lot and need the boot, then your only option is to fit a pair of underseats to get a solid bass thump

Which underseat sub are you using and how much did you buy it? How much also the ported sub? Have you factored in the price of the power amp to drive the ported sub? Because underseat subs usually already come with built in amps, so to compare with big sub boxes, you need to also include the necessary power amps (or compare with built-in powered sub boxes).
Of course the main limitation of underseat subs is physics, more exactly space as it only has very limited space to work with and therefore cannot move as much air to generate big bass as regular sub box.

underseat subs... I wonder which model is the best ones. Focal iBus 2.0? or the Alpine one?

I bought Infinity Basslink SM 8" from xciteaudio.com
RMS 125 watts and built in class D amp (written on the box but who am I to judge)
Has good bass in my opinion but maybe not boomy enough for me. Maybe if you frequently listen to soft music and those usual pop or jazz genres then it would work wonders since it is mainly focused on SQ.

The other sub i bought is a cap ayam brand audioquart (Huricane series if not wrong) and also normal audioquart 2 channel amp to power it. Add in installation and sub box and wiring (did not change HU and previously installed Hi/Lo converter for the underseat so no need to pay for another one), only cost me 550. Sub rms is said to be 500 at 4 ohms but i'm not so sure and the 2 channel amp i am not sure how much power, but the box did say 180W x 2 bridged at 4 ohms so that's that.

Quality wise, the Infinity takes it all since it has nice clarity and a clearer bass thump which costed 1.1k alone exclude installation. But since i just wanted boomy bass, the cap ayam fitted the bill. Just not sure how long the amp will last

Diff ppl got diff taste. Not everyone can take the bass of a sub box

Yep... Forgive me for being a basshead...

So, where's the Infinity Basslink SM 8" now?

Why? You wan ah hahaha
Still hooked inside my myvi along with the cap ayam boot sub hahaha

I am trying to strengthen the audio, since the factory speaker is shitty.
Any recommended item to get to strengthen the base?
Was thinking of underseat mbq but was reading the review its kinda waste money

Budget around rm500 with amp.

Any suggestion?
And i am new to all these stuff tho.

its birthday present for my friend

What does it mean by mid range driver?

The 6.5" speaker... have you tried demo or listening on those 8" active woofer under the seat? Maybe you OK with it but to me... totally not acceptable....

And anything slightly better than the underseat thing? I am ok with a box behind a car actually. As just want to strengthen the base more. Any suggestion? As adviceble is the sub in a box or sub mounted to the car is better?

As my friend is driving a sedan car, does the bass wi be weakened since the woofer behind the car is far away from the driver's ear?

And hopefully does not remove the factory speaker just wanted to add a woofer or sub woofer

Can settle everything in rm500? With amp.

Depends on the loudness..

Go for demo...underseat seat use small driver (6-8inch)
It need to be close to your hearing, and the air flow available not enough for high volume..

A box is the trunk is around RM100-300
Driver (subwoofer) around RM300-1200
An amp either 2-channel or 4 channel (drive front speaker also) cost a lot more...

For RM500 can only get active underseat
Or used subwoofer box, sub driver and amp..might be..

If youre satisfied with 6-8 inch driver for bass, then go for it...i think low volume is ok.

For me, even 10inch is not enough...currently using 12 inch sub

And so i google the woofer. Normally i saw its cone with 2 hole means 2 base(i not sure what is it called) does it come with only 1 bass? If rm500 exclude amp? Because i can get amp at rm50 at my friend place.

Can i just install the box without the sub woofer? Or just the sub woofer without the box.
Or its 2 same thing?

Sorry i have totally no idea in these stuff

Hello sifus here, just recently got a new Mazda 2, the sound system is ok, but i want a little bit more bass, so considering underseat woofer like Nakamichi. What i want to ask is can i just use my stock car sound system and add the woofer without adding an additional amplifier?
