yaaay..like i said to vivek the deed is done..finally..after all the pondering and stuff..

btw navin u are right..he can make his own wires,we discussed that but one problem is we didnt want to take a risk with the car electricals..one mistake somewhere,one small short circuit and boom ur entire wiring,ur ECU,ur car goes kaput..so we decided to get some company made cables and stick to the safer side rather than experimenting..at home this can be done as its safer,u burn only the wiring but in a car the scenario is different..thats the only reason viveks buying cables and not making his own..but i know ud beg to differ on this..

PS : btw the last i heard from vivek he went back home to open up his newly bought amp to see whats stuff are used inside..thats some DIY spirit for u but id call that madness

..new amp and ud want to open it..naheee..

I meant I did not want to take a risk with the DIY amp. The cables should not really be a big problem.

hhhmm..forgot to tell u guys..had been to viveks place today..saw his DIYed home theatre speakers..drool drool..im very impressed..after seeing that i too have decided to do some DIY guys..inspired by our DIYers navin and vivek..

4 SWG will do fine for 1 or 2 amps totaling about 400 W rms output. They will draw about 40A at full output so a 60A fuse is sufficient.

Get good stranded power cable. I use stuff we get Polycab with a poly sheath. I am trying to find some with teflon/poly combo sheath but so far have not been successful. remember the power cable should be felxible enough to run under carpet and around turns. At home I'd use 7x18 you can use that in a car. for RCA wire i first made my own using instrument 100/40 (sat) and 100/38 (sub) wire. instrument wire is usually OFC nad has 1 tinned so it is easy to trace.

I have some self developed odd colour code that i have followed since the 80s.

Power: Red for Power. Black for Ground. Blue for Remote.
RCA: Yellow for Sub amp. Purple for Front and Green for Rear.

Follow your own drummer Vivek, march to the beat in your head.

I have scant respect for the products of most manufacturers since they are built to a price point and target audience that I do not represent. I respect the manufacturers (not their products) as they have to turn a profit and have shareholders to answer to. As a DIY we have neither objective and we can design our systems to match our own taste. That's freedom.

Today there is a Audio show in Mumbai. I might visit after lunch.

I wonder where we get Polycab in Bangalore. I saw that Finolex makes power cables for automotive use. But I am not sure if it is available in small quantities. I need to get a fuse box also.

Autophile · 11th November 2005, 12:51

Vivek

You need fine strand cable for DC use...minimum 4 guage if you want to have two amplifiers.

Am sure u will find ur ploycab cables in SP Road( Majestic Area). The google search for polycab showed many places in Bangalore BVK Iyengar road, residency road, Malleshwaram etc..

Vivekphadnis · 12th November 2005, 00:04

The problem with most of these fellows is that they will not sell branded cable in small quantities like 5m or 10m. Do any Bangaloreans know any particular shop where this will be available?

Does the fuse have to be that box kind of thing which comes with the branded wiring kits. Will the regular electrical stuff not be sufficient?

I just bought Boss interconnects for the HU to amp connection. Rs 450 each.

I think I will buy 4 SWG just in case I decide to add a sub and amp later.

Vivekphadnis · 12th November 2005, 16:26

I bought the power wires. The conductor is about as thick as a pencil and the shopkeeper told me it could carry 71A. That should be enough I think. And the strands are thin as JB said.

navin · 14th November 2005, 09:14

Vivek it should have in excess of 100 strands.

Vivekphadnis · 14th November 2005, 15:28

That bloody wire was so difficult to manage. I just went and bought a Boss 8 guage wiring kit.

navin · 15th November 2005, 00:40

Naheee! Vivek, you bought a ki? you could not find stranded 4WG cable in Bangy? what kinda town you live in? :-)
