yup you're right, it seems there is no common 20sq mm = 4ga power cable

After much deliberation and thinking I have dropped the idea of going heavy on my Linea's audio upgrade. As of now I just want to upgrade the stock speakers for a little bit more bass. So looking at the least expensive speaker upgrade for my Linea and that would be driven by the stock HU.

Front - I was looking at the Blaupunkt 65.2 Components (@Rs2839) or Blaupunkt VC 652 comps (@4098)

Rear - Polk db 651 coax (@2939).

I have tried finding reviews and i couldnt find any. Request the members here to shed some light on the choices I have made.

Cheers!

4ga / 4AWG is 21.15 sq.mm. The nearest Indian equivalent is 20sq.mm.

What is the rating of your amp? At a pinch, you can actually use 16sq.mm. without being anxious about voltage drop over that short length of cable. 25sq.mm. would be an overkill both in terms of stiffness and crimp lugs.

OFC is associated with speaker cables, not power cables which only carry DC.

The last I had tried, and found that it has no effect, was in 2007. I anyhow don't use equalizer or any other modifiers, neither in the iPod nor on the HU (Kenwood Excelon).

Alas, I was in Delhi for a couple of weeks in October - would have been nice to meet up. Maybe next time!

The VC series is far better in terms of midbass and highs (neutral, not bright).

Please audition it in a car. Polk DB series can be shrill / bright for many. You shouldn't be disappointed after buying.

Both Blaupunkt and Polk Audio are very bright in my opinion, having had both brands in my car over the years. I would suggest the Hertz ESK series, as I found it easier on the ear. While I understand you have budgetary constraints, I would suggest you up your budget some and look seriously at the Rainbow EL C5.2. These are superb quality and available on motorheader.com for Rs. 11,690. The experience will be vastly different from what you're used to with the usually available brands (Blaupunkt, Hertz etc). You can buy something very basic for your rear fill speakers, but I'm a firm believer in investing well on the front components, to avoid "upgraditis"

Need your help.

I have been trying to design pods for dayton audio dc28f.

The issue is, I am trying to mount the tweeters on the a-pillars utilising pvc pipes cut to shape so that the tweeters face the headrests diagonally.

However, I have no idea as of now on how to mount these pods on the a-pillars.

Pls suggest solutions.

Attaching the pics for reference.





The other option is that I attach soehow these pods on the dashboard, somewhat like this:

I think using something spherical might make more sense. a cricket ball cut in two or 2/3d?

Is it possible to separate the tweeter from that massive base-plate? If yes, I can share pictures of my custom aluminium pods, if you can PM me your number. If you can't separate them, then you need to do some fibre-glass fabrication on your A-pillar trim.

This is routinely done by both Driven and Motor Concept in Delhi, for mounting the mid-bass unit of three-way components. This doesn't appear to be much larger than those.

It should be. Parts Express sells a truncated base plate for the same tweeter

I have been looking for some small desktop/laptop speakers so that I could use their body to fit in these tweeters and mount them on the a pillars using nuts/screws.

I am not competent enough to separate the flange from the tweeter.

THanks. I am going to give it a try. But I do not know how to separate the flanges from the body.

You can get them fiber glassed by someone for a better symmetrical shape with A pillars and also aim them better. Just my 2 cents, it wont cost that much as well and should look way better.

Thank you for the reply! I have heard the polk db 651 comps+coax combo (with an alipin cda117) and it is quite bright but had nice punch as well. Thought that the brightness was due to the comps up front. My idea was to compensate for the lack of bass with these polk coaxs at the rear. Whereas the comps up front will be neutral but clear.

Thank you for your reply. I would defintely try looking at the Hertz but the rainbow is clearly over my budget. That said, another reason for me to go basic is also that the speakers would be limited by the Stock HU. Beyond a point I thinkthe speakers arent going to deliver anything significant thanks to the HU.

That's not right. I've found that speakers are what counts when it comes to sound quality, even if you don't connect an amp within the setup

My point is more around investing on the right hardware once and sticking to it after. This is a lesson I learnt after spending incrementally on upgrades (and I spent a lot more than I realized incrementally) and not getting desired results. And if you love music in your car, like I do, you'll get upgraditis, unless you get stuff that satisfies what you're looking for

What is the rating of your amp? At a pinch, you can actually use 16sq.mm. without being anxious about voltage drop over that short length of cable. 25sq.mm. would be an overkill both in terms of stiffness and crimp lugs.

OFC is associated with speaker cables, not power cables which only carry DC.

The terminals don't seem to be big enough for 4ga but I can use gauge reducers for that.

Here are the specs of the amp:-

I checked out the Polycab 25 sq.mm cable and it was very flexible but it had just one layer of pvc on top of the copper.
