hmmmm did quiet a lot of research on this when buying the audio system for my swiftfew months back
..but my budget was only 25k ..cause ive always felt that no matter how much u spend u just dont get that quality sound and effect in a car..automobiles were never made to listen to music .
anyways for 40-45 k..you can get some really nice stuff from JBL,infinty,hertz and all.
dont go for Sony at any cost.
coming to the system
1)get a pair of component speakers for the front.swift holds
5.5\6 " speakers .. (i am not sure)
component speakers = mid range+tweeter+crossover. (set of 2 (left +right)
2)for the rear get a 9 X 6 " oval speakers.from JBL\Hertz
3)incase you need tight bass get a 10/12" sub fitted in an enclosure.
or if you want some boom boom kind of bass you get tube subs ..and all
i would say go with the one fitted in enclosures..
4)you will need a 4 channel amp for the front+rear.and a mono\2channel amp to drive the sub.
incase it shoots your budget just get a 2channel amp +mono amp for front and sub. and connect the rear's directly to the payer.
5)about the player ..i really dont know much about the dvd player's but ive heard that JVC makes some value for money head units ,with USB support and all. but that will be quiet expensive and wont leave much cash for the other stuff.
incase you want the normal single din mp3 players .Pioneer makes really good one's like the 7950 UB. which has USB support and all.
i am laying more stress on USB\external PMP support cause i got the 6950 IB which doesnt have direct USB and now its very boring to burn cd's just for the car..as i burn most of mu backup of music on dvd which my player doesnt play.
i hope youve got a idea of the total ICE (In car entertainment)
for the best recommendations it would be better to ask Sam/Low_bass_maker et etc.on Team-bhp . or just follow the link above.
the total split of budget should be something like this.
Head unit-10-13k (20-22 K If dvd)
front components-7-8k
rear co axial (9 x 6)- 4-5K
sub-5-7k
4ch.+ mono block-7k+ 3-4k
here's a totally JBL'ified system which u may get..but i guess for 40 k u can better stuff not sure.
Front doors: GTO 607C components
Rear: GTO 937s in a wooden tray
Sub: CS1204T
Amp: GTO 75.4 + monoblock.
HU - Pioneer 7950 UB
PS:
good wiring and installation is one of the most important part of a ICE system
.see to it that you get it installed from a professional with good quality branded wires. set aside atleast 2-3k for wiring ,installation maybe done free of cost if all the stuff is taken from the same shop.
