Since the time I got my Brezza, I always felt ICE needed enhancement to have better experience with the music. However, I was always confused as to how to bring the experience upto the level of my expectation and attain Nirvana
Disclaimer:
There's no installation pics I captured due to the tensed situation I was in at the very moment as I was counting on my electrician to get things right. Also, this review is purely on the product rather than the usual installation process since this is no "DIY". Once done with your purchase, please do consult your trusted car electrician for a clean installation.
Then, my next question was, what do I do?
- Change the entire speaker set of Hertz to Pioneer or JBL? This was a bit expensive idea. On the other hand, I am not an audioholic to understand the basic terms of music world. To me, I wanted pure vocals and bass upgrade. So I was okay with the current setup but felt the oomph factor was missing when the music started.
OR
- Just add the Sub-Woofer alongside a decent amplifier. Okay, which one and what wattage should I go in for? Again, I didn't know or understand anything related to this question as well.
When I failed to arrive or get any answers to the above questions independently, I started googling and YouTube'd a lot to understand basics in Music. Again, somewhere it didn't convince me.
So lastly I came across these 2 terms, Active & Passive Sub-Woofers. My mind starting getting curious to see if this would be it. Never knew there were 2 categories in the woofers as I only knew there were Sub-Woofers. Okay, what are the main and basic difference in the 2?
Basically, a subwoofer is used to reproduce low frequencies. This is indeed an essential component in making your setup complete. There are components as well these days to compensate the absence of woofers. IMO, I do not have first hand experience to this and didn't want to risk the investment on something that I didn't know a thing about. So, I stood with subs.
Passive Subwoofers, are mainly powered by an external amplifier which is exactly the way any loudspeaker is powered. You can play around with Passive subwoofer setup by either getting a good amplifier with proper wattage to produce bass to disturb your neighbors or fellow travelers when you stop by a signal. It all depends on what your requirement is. But this does produce and proves to be better in terms of reliability and servicing because they are independent components in the music setup. Amps are usually kept under the seat and woofers usually in the boot. This setup will syphen more money from your pocket.
Active (or Powered) Subwoofers, are those that have an inbuilt amplifier. This type of subwoofer is a self-contained speaker/amplifier configuration in which the characteristics of the amplifier and subwoofer are optimally matched and are both encased in the same enclosure. Basically no need to buy a separate amp but you will have to look at wattage specification before buying one. You will have to be bothered about the wiring and then you are good with just one box sitting in your boot and need not have to worry about the additional amp.
With the difference understood in layman terms, I finalized on the Active sub setup influenced by the finance in hand. My search then started with various websites to find out good reviews about the active subs and I came across this affordable small wonder
Blaupunkt GTb 8200A product. I started getting inquisitive about the performance of this sub and went on observing feedback from various other users and I ended up zeroing my selection. I sourced this through
Amazon finally and I got it for reasonable price i.e. Rs. 6,000/- during online sale while it was actually retailing somewhere between 7-8k. I booked one without thinking much. Specs are as below:
- Ported subwoofer enclosure with integrated Class-D Amplifier
- 8" subwoofer with spun paper cone
- frequency response: 30-200 Hz
- amplifier delivers 75 watts RMS (200 watts max)
- line- and speaker-level inputs
- separate controls for low-pass filter, phase and gain
- dimensions: 10"W x 10-1/4"H x 10-3/4"D1 x 8"D2
- warranty: 1 year
Make no mistake, all the tech details for this sub is lifted and dropped from
here. This sub is accepted by audioholics both in domestic and as well as in abroad. It was more than enough for me to make a firm decision on the setup, and it was indeed Active Subwoofer sourced from Blaupunkt.
I placed an order in Amazon on 26 Oct and got it delivered on 29 Oct. Seller was quick in having the item delivered as the initial estimate was to deliver the product on 01 Nov but I got ahead of the date. Packaging was brilliant. So 10 stars for the e-commerce website and the seller associated with it.

As soon as the product arrived, I was really excited to have it installed on the same day. But as the saying goes "
Man proposes, God disposes", mine was something similar "
I proposed, Electrician Disposed" of not being free for installation due to other cars in the line for other works. So, the plan of installation moved to next day, i.e. 30 Oct.
I woke up and drove straight to his workshop to get this device installed and enjoy the bass. But, I had various hiccups.
1) Active Subs need different type of wiring since it demanded an AUX cable which I didn't know. Seller had sent the power and ground lines alongside a fuse box. Didn't know I had to buy RCA cable. I later bought one with 5mtrs in length which costed about Rs.450/-
2) My electrician had not installed active subs till date, since he had fair amount of experience in installing the passive ones alongside an amp. So, I had my doubts creeping in if the installation would happen the same day because he was planning on understanding the product first before getting into the job of wire splicing. By then, I was running late to office and told him I would come back again and left for the day
3) He also mentioned I would need RCA converter as well, since my HU from Maruti didn't have an RCA output. I inquired in multiple shops in EC, Bangalore - but to my dismay, I didn't find any. Plan got postponed again because this main part was required. I didn't know how that converter looked like and my electrician sent me the
link for the converter that was essential in completing the job. It was available from Amazon but it was pricey.
4) I then went ahead with the normal RCA coverter from another maker MiGagdgets which I sourced from a local store in Mysore over the weekend for Rs.750/-.
Please note this HU is available on the top end variants of Maruti's current line up i.e. Dzire, Ciaz, Ignis, Baleno, S-Cross & Brezza. My electrician later realized he could have taken the power and speaker output directly from the rear doors of the car.
Finally on 6 Nov, my electrician finalized the installation and it was all good to be switched ON for the first time and it did sound great for its size. We did meddle around the setting knobs located in the sub itself to get good output and finally arrived at a good setting. Attaching both the settings of the knobs and the subwoofer;
Reviews and Feedback were genuine in this case and it turned out to be a success. Sadly, I cannot record a video which would give you the exact experience if heard in person.
My rating for the product stands at 10 on scale of 10!
List of items required alongside the sub purchase - not mandatory though as it's totally dependant on how you power the sub, either through the rear door speakers or from the HU itself - Let your electrician take a call. But ensure he doesn't screw up with wiring as it could lead to other repercussions with the electrical systems of the car.
- RCA Cable - preferably 5mtrs in length
- RCA converter

With this tiny little enhancement, sound output and the experience of music has increased exponentially and I come out here as a satisfied customer. I highly recommend this sub to others as well who comes across short of knowledge in sound department and are inclined towards enjoying the music by upgrading or enhancing the current setup. However, I’m not sure if this sub is going to be effective for sedans because it’s pretty small and I’m not sure if that’s going to prove itself like it does with compact SUV’s, Hatchbacks and to some extent the SUV’s as well.
