While it would sound pretty good, it would be nicer to have a little more power.

Your question was answered by Sam bhai before. By 120W, you mean a 60.2 or 60.4, right?

Here, Sam bhai again:

I do not think it will be enough to drive a subwoofer in a sealed box (which definitely needs more power). More is better. However it may be interesting to drive a tube with this amplifier, especially for those on a tight budget.

The F250 is a bridgeable amplifier. AFAIK, if you can dedicate all 4 channels of the amplifier, you'd get 100X2 - which is a much better bet.

ill get the gt5 a604 (60.4). then i guess ill use the mrpf250 to drive the sub and the gt5 amp to drive the 6x9s and the alpine ao-axials.

thanks alot guys.

The F250 is rated 40Wrms x 4 @4ohms, 50Wrms x 4 @2ohms. Optimally, if the GT5 is dual VC, you may be able to pump in (2channels bridged x 2) 160Wrms if the coils are 4ohms each, 200Wrms if 2ohms each. If the GT5 is single VC, you can pump in only half that with 2 channels of the F250 bridged.

Don't worry about the 100W amp v/s 250W capability of GT5 - even 100W might be loud enough, though not loud enough to churn your insides. For that, you should get a mono (10K additional minimum) to drive the GT5 - but that is not your objective.

thanks deralte. it is a single coil 4ohms sub if that helps?

Since it is a single coil, the only solution with 80W is to use a Bass Reflex (ported) box as Sam had suggested. This would make the 80W sound substantially louder than with a sealed box.

The data sheet / manual that came with the sub would have the volume indicated for a ported box, as well as the TS parameters. PM Navin / LBM to double-check the box volume and port dimensions for the GT5 sub with the GT5 TS parameters.

Akshay1234 · 5th December 2007, 14:47

will do that. thanks alot deralte.

Sam can we have some details about GT5 series Mono Amps?
This weekend i have to buy one mono amp and subwoofer kindly suggest in GT5 or GTO series(earlier my choice was GTO301.1 with GTO1204BR or BP now it looks like became old so wants to know the latest compared to them).
Sorry if its offtopic.

Sam Kapasi · 8th December 2007, 08:20

Your question is not off topic. The GT5 monoblock will be released in January/February 2008. Not before.
The 301.1 is still available before it is replaced by the new GTO monoblock (refer to new ICE products 2008 thread).

Sam Kapasi · 14th December 2007, 21:47

I am happy to inform you that (finally, whew) the GT5 amplifiers have arrived.

There is a new 2 channel model called GT5-402 - priced well at Rs. 4,990/-. It has everything you need in a 2 channel amplifier including LPF and HPF with variable frequency cut off.

The 4 channel model that replaces the CS60.4 is the GT5-604 that now costs 7,990/- The new designs are breathtaking.

They will hit shelves in 4 days, across India. Be careful of what you pay, specially in North India. Overcharging is the custom there.

Sam,
What is the difference between GT5 3001 and GT5 604?

Sam Kapasi · 14th December 2007, 22:17

The GT5-3001 is a monoblock. The GT5-604 is a 4 channel amplifer.
The GT5 monoblock has not been released as yet. It will come in 2008.

Good pricing. with the dealer discounts, if any, it should cherry on top.

One kewstion pleeze, are they better in terms of overall performance then the CS 60.4 and also is the GT 5 equlilant better then 300.1, just curious as I own these baby's.

Sam Kapasi · 15th December 2007, 08:45

All GT5 products are freshly built and not derived from any existing platforms. So I guess my answer is yes.

Another thing that is IMMEDIATELY noticeable. The GT5 speakers are far less bright than the CS series speakers.

JPL · 15th December 2007, 09:42

Apologies for making you repeat yourself, I read the entire thread in its entirety and I get the picture now !!

I wish JBL starts upgrade scheme lol, these amps are gorgeous and the 2ch will be hit i guess
