advice needed: car audio in hyundai accent

Autophile · 12th October 2005, 18:56

Like i have mentioned in my earlier post. When you have the subwoofer mounted in box placed in boot. You need a more power to get bass in the cabin and also the bass tend to loose its definition. And your boot suffer from rattling and vibration.

You tend to drive your subwoofer more in order to get bass in cabin because of 3-4dB of SPL drop between in cabin subwoofer (mounted on parcel shelf) and the subwoofer (mounted in sealed / ported box) in the boot. So to get bass from boot mounted boxes you need more powerful subwoofers and amplifiers.

My suggestion to you is that you go for free air install in the parcel shelf.

If you want to go for box then terminate the port openings in the parcel shelf so that you get the reflex in the cabin.

JB, I think this porting of the sub is some loose version of a band pass. where VB1 is huge and VB2 is smaller than VB1. Usually in traditional band pass subs VB1 is 1/3 or 1/2 the size of VB2. In this case VB1 would be about 10x the size of the Vb2.

I have not had time to work out the mathematics for this but i guess it will work quite well. Do you have the time to figure out this. It would help me.

An advantage of this technique is that the ports can be tuned to taste and the ports need not be of equal length.

I wanna add this sub woofer in my Swift. This would be powered by a sony 504 in the bridged mode.

Around 2k to 3k. Its in that price bracket!

SoundManiac · 13th October 2005, 17:46

Thank you aseem. And untill we have Autophile's word on it, can you give your opinion? Which sub to be powered by Sony 504, best suited for SWift.

It depends on your budget, the type of bass you like, the amount of space you are willing to sacrifice......
Good budget subs are Pioneers (starting around 2.5k onwards). If you like tight bass, than you can go for a Pioneer 306C sub in a sealed enclosure made of MDF board.
If you like low and boomy bass, than you can consider JBL CS 1200T bass tube. It will require a lot of space in the boot. But your amp being underpowered would be able to drive it to its potential, as the tube has just 150W RMS.
If you are looking for a slightly expensive setup, and want bass that travels far, than you could consider JBL 1000D or 1200D subwoofer with a ported box for 5.5k upwards (gray price)!
If you want more options, than consider Hertz, ID, subs. They start from 6k upwards for a 10" sub.
So in the end it all boils to, the type of music you like, and the money you are willing to spear.

aseem bhai

do u knw the grey market price of jbl's cs1200B

amit_baghe · 13th October 2005, 22:54

grey price of cs1200 jbl tube is Rs 6000 approx and Rs 6000 for 12" kicker

Which would give more boom boom, sub in tray or sub in ported box( in boot)?
Is it adviced to do free air installation for Kicker 12" sub, model no: 05C124

Is it true that sub installed in the tray requires less power to get bass into the cabin as compared to ported box in the boot of the car?

the sub in a tray will definitly give more boom boom but less definition than a sub in a sealed or ported box.

yes the sub mounted on a tray needs less power as compared to one in a ported box or sealed box.

for a sub in a sealed or ported box a monoblock amp is needed for the sub to perform at its optimum level where as a dececnt 2 chan amp will easily be able to drive a sub mounted on the tray.

Thanks for your input guys!

Say I have a budget for max 9000-10000 bucks.

Which sub? or which sub+amp Combo? for Swift HU Pioneer 7750.

Like the bass tight and loud.

Autophile, Gunbir, Navin, and Sam, all others not excluded. - your takes please.

Sam Kapasi · 14th October 2005, 11:49

When I get my swift, I'm putting in a boxed subwoofer....

navin · 14th October 2005, 12:27

If you want to leave the sub in the car get the box otherwise get the tube and tune to port to taste. I find the tube lighter than the box.
