Any good installers in Hyd please

MY config:
GTO 937
Pio 5990 IB

upgrade plan:
GTO 4-12[ which is better sealed one or 1204 BR
GTO 607 [ without cutting how will 507 sound for this config]
GTO 75.4[ do i really have to go for this or would 60.4 be sufficient] ?
Scoche 2200/- for wiring

Been to MOTOAXIS ... he quoted 1900/- for the installation itself

Pls suggest a best audio system + speakers in the range of Rs 10,000-15,000.

choice 1.
HU: Blau or Pio : 8-9K
Front components: 6K
you can add an amp or sub or both later.

choice 2.
HU: 4K basic HU from Pio (2950?) or Blau (Mumbai?)
Front coax: 4K
Amp: Sony 554 for 5K + 2K for RCA wires (7K)

1. Between the 4-12 and the 1204BR, the choice would depend on your listening taste and your budget. A GT4-12 in a sealed box would run to 6.5K (5k + 1.5k). The 1204BR (basically a GT4-12 in a JBL-made ported box) is 9K.

2. If you're cutting the door-pad anyway, I'd take the 607c over the 507c siimply because it will give much better bass response.

3. If you go for the 4-12 in a sealed box, you'll need the GTO75.4 to do justice to the sub. A 1204BR will be ok with a CS60.4, but a 75.4 will do a better job

4. Wiring sounds good enough (rates, I mean). Scosche is a good brand.

5. I think 1900/- is quite decent for the work involved in your install (if he does a good job).

Thanks Hydrashock

1) I listen to lot of HOUSE music may be ( always) and DISCO .

2) in SPROCKET he was talking about some fibre glass for a 607 and said damping is not required if i order that one it costs 3400/- wht does he mean ?

Hi,
I was wondering if it would make sense to install two 6.5" woofers on the rear hatch of M800 using MDF planks? and install 6x9's on the sides? This way we can have good sound as well as boot space on M800?? Audio experts please recommend!!!

Regards
Gopz

a 6x9 has about the surface area of a 8" speaker. I assume the 6x9 you intend to install will be in boxes.

I dont think the 6" woofers will add much to the bass provided by the 6x9s maybe a single 10" woofer in teh rear hatch might help more.

I'm no expert so don't act on my advice. As I understand it, if you need boot-space, you should go for a pair of 6" x 9" ovals on an MDF tray, so that you get some bass. If you can spare some space in the boot, install a sub. It might even be possible to install a sub in the spare wheel well. It is in the Santro. If you do a search you'll find info & pics. I'm not sure about the M800. Experts?
Front stage is most important. So think of components there. I am sure the experts can advise you on how to fit them in the M800.

ketchup · 15th May 2007, 11:22

Many thanks for your inputs folks. I'll head out to Sprocket Hyd today.

But still... can anyone describe the difference between the sound of GTO and CS, I'm not sure if I'll be able to tell if the speakers are not set inside a car for auditioning.

I am really not sure how much more effective is the 75.4 over the 60.4. Under standard conditions, a difference of 15 watt RMS should not contribute much to the increase in loudness (in dB).

According to: Speaker Power Ratings and Amplifier Power Ratings

You need, twice the power to increase the loudness by 3dB for the same given set of speakers!

I'd really appreciate if someone who has tested both the amps gives a feedback.

Thanks Navin & Nura, I will check with Auto Fusion.

I agree with you 100 % but there will be a bit of headroom for the speakers to play clean....also the bridged output of the 75.4 is much better than that of 60.4...and in a setup of one pair speakers and a woofer the 75.4 is the excellent choice.....

romyeo4u · 15th May 2007, 17:06

Alrite.... thanks everyone for all the suggestions . Finalised on 75.4 and GTO 607 , 4-12 sub and my existing one is GTO 937 rear Pio 5990 ib front CS 2104 .

waiting for the order!

Ketchup: Have you been to SPROCKET , mention your price quote as well and do mention that you are from TEAM BHP and SAM [ knows you } it pays.

Here are the power ratings:

JBL CS 60.4

RMS Power at 4 Ohms 60 W x 4
RMS Power at 2 Ohms 80 W x 4

JBL GTO 75.4

RMS Power at 4 Ohms 104 W x 4
RMS Power at 2 Ohms 142 W x 4

So my assumption that 75.4 is only 15 W RMS more powerful than 60.4 is wrong.

. But I must say that the naming convention is not consistent. Why did they name it 75.4

I think the 75.4 was rated (75 x 4) at 12V and the 60.4 (60. x 4) at 14.4V. Sam would be the person to ask.
