Having a 2 subs will surely make difference even when listening music at low level. Am not sure what Frank is looking at if looking at even High level SQ bass, a single GTi would hit about 130-133 db spl with 1000W. That's loud enough to fill one's SQ requirement. No doubt the Xmax will be stressed at this level, but than again that's what Gti subs are meant for. The other solution could be gettng a ported enclosure in which the Gti works the best, about 2cu.ft with port tuned anywhere below 35hz which might push the SPL further more.

nahi. i really dont think I will need the services of two of them. boot space is slightly at a premium, and this sub itself is huge enough to give me headache as to where to place it.

you can kindly place it in my Skoda!

However I can assure you that this placement will not improve the quality or quantity of bass in your car.

guys. i need suggestions about the enclosure. Ajay bhai has suggested an inverted install with a sealed FG enclosure with a volume of 1.2 cu ft.

I was also thinking along the lines of an MDF enclosure with a Plexi window. This design has been suggested by Invinsible.

Here's how it looks.
Which would be better? I would prefer FG since one can make it look plush and utilize a nook/corner in the boot.

The mDF/Plexi with a few lights inside would look like 'cool maal.'

Waiting for suggestions. I know for a fact that the FG enclosure (if made thick) will sound better. The MDF/Plexi enclosure might have air leakages due to plexiglass and the plexi might flex too..
Please advise!

Dude please don't do the plexi, go for the fg with mdf for flat surfaces, lots if bracing and 2 layers of csm, you won't regrett.

That box design was suggested considering 500 rms amp that was available before. With the new amp I suggest you get the enclosure made in 1" MDF on all sides accept the front and the top baffle which would have the plexiglass. Needs to be done with 1.25" -1.5" thickness.
The plexiglass will be 18-20mm. Also make use of bracing on all the joints with layer of FG on the inside wall of the enclosure. Add 16-20ounce of poly fill on all the inside sidewalls to cut/absorb those standing waves.

Complete FG sealed enclosure in this case might take same or more amount of space since the mounting depth of the sub itself is around 10".
Also i strongly suggest the enclosure would need to be around 1.3/1.4 cu.ft net volume for a good low end ext. output.

Adding some LED would be great

Also I like to add that FG enclosure might add a bit of resonance unless it's deaden, although many would disagree here. A good FG enclosure would require minimum 4layers and good 8 layers. You could also use HDF/HDP instead of MDF. i would still go in for a good MDF enclosure.

Frank wrt light I have one rule for Audio - "If you want lights go buy a christmas tree".

Go FG. The enclusre will be a triffle smaller as the wall thicknesses will be less.

Hmm. So fibre glass vs mdf seems like the debate all over. yes, FG has to be thick.

Which one of the two has better acoustic qualities?

I second this. The sub will look good inverted and you can add some bling bling neons to the setup
