Hi guruji log,

A friend of mine got impressed after i told him all about team-bhp forum, and the kind of suggestions you people give. He cant post on the forum as he does not have a PC.

He wants to know from u people about the RMS power of Sony 500W xplode amplifier. He tried to find out a lot about this amp, but none dealer is saying about the RMS power. All they say is that, it is 4ch amp with 500W peak power.

Please reply,

Why the heck sony is trying to fool people!!

Amit Sony's Indian website mentions the specs of all amps that Sony sells officially in India. I am not sure which amp your freind is trying to buy? Whats the model number? Is he buying Sony 504? As thats the only budget amplifier that Sony officialy sells. It has 60W RMS per channel.

For a ported sub box, does the size of the hole in the box make any difference to the bass effect produced? If yes, then please specify the size of the hole as i am getting a custom made ported box for 12" kicker sub, powered by pio 6100. Remember 6100 is also powering my rear speakers. Setup is 60 x 4 type.

Thanks.

I guess i am doing a lot of R&D before getting the setup done in my car!!!

Amit,

Give me the model number of your Kicker sub and i will give you the box design.

For ported box both port diameter and port length is important for tuning the box. And good quality flared ports are must for subwoofers.

Amit,

Your car is Accent...right..there are three options for you to install the Kicker Comp VR subwoofer :

1. Free Air Installation (a.k.a Infinite Baffle) : The Kicker Comp VR can work fine in free air install (mounted in the tray)

Remove the original parcel shelf. Make a custom parcel shelf from 0.5" MDF. Bolt it to the original metal shelf with foam sandwitched between MDF & metal tray. Make sure you seal all the corners and leakage with foam or silicon sealant.

This is the easiest way to get in cabin bass and you don't need much of power.

2. Ported Box : Kicker recommends two boxes for this subwoofer. The difference is that the sub will play deeper in bigger box and require less power.

So if you want thump go for bigger (SPL/Deep Bass) box if you need more definition and less thump go for smaller (Compact) box.

In Compact Box case : The 1.75 cuft is the volume of the box, 2 X 12.5" is the port mouth dimension and 16" is the port depth (hence LXWXD of port = 12.5X2X16) its not a regular cylinderical port, its a square (slot) type port and it is a part of the box itself.

Similarly are the dimensions for the SPL/Deep Bass box the only difference is increased volume and little more length of the port.

Typically i would like the port openings to terminate in the cabin through the parcel shelf but in case of slot port its a little tough job. Had it been cylinderical ports it would have been much easier.

3. Sealed : Same difference between the two box's sound. Its without the ports hence easier to build but you need more power to get the bass in the cabin. The bass will be tigher and more defined than ported in this case.


In case of option 2 & 3 the boot and the number plate will rattle a lot. so you need to damp the boot.

My suggestion to you is that you go for the option 1, make the parcel shelf with close tolerance and seal it properly.

I assure you that the bass will be deep as well as defined. And most important it will be in cabin.

Also make sure you use Subsonic filter (if any) on the amp in Option 1 & 2 at 25-30Hz. Without that the sub will handle less power and in case of ported you can get port noise (though does not matter when the sub is in the boot). But to increase power handling of the subwoofer Subsonic filter is better to use.

Also the amp is easy as the powersupplies of the amp don't run out of juice due to the increased load presented by the subwoofer in reproducing subsonic frequencies.

The only problem is that this filter is present mostly on mono's and sub channel of multichannel amplifers (e.g. Alpine MRV-F450).

Autophile, your post was perfect. That single post of yours has clarified many of my doubts.

As you said that you would prefer option 1 ie Free Air, but aseem bhai said he would prefer ported box. I need a final suggestion, because i wont be in a position to test both the setups, as i said that i am ordering a cutom made box. If the box is made, the installation person is going to charge me for the box even if dont buy it.
