Advice on DVC subs

dinu2506 · 25th February 2008, 20:59

Dear Gurus, I have recently upgraded the audio on my Honda Civic with a 4 channel amp for the 4 speakers and a monoblock amp for the sub.

I have a JBL GT5 12" sub that has a 4 ohm impedence. My monoblock is a JBL GTO3501 with 225W RMS at 4 ohm and 360W RMS at 2 ohm. Since my sub is a 4ohm impedence, the mono pushes only 225W RMS. What are my options for presenting a 2 ohm load to the amp so that it can push its full 360W. I do not want to add one for sub in parallel.

If I put a 4 ohm dual voice coil sub and wire it in parallel, I should be able to get a 2 ohm load. Will this be a good option to fully exploit the mono amp? If so, can you suggest some brand of subwoofer that has a 4 ohm Dual voice coil that can be wired in parallel. I searched the site but JBL only has 2 ohm dual voice coil sub, which if wired in parallel will present a 1 ohm load which my amp cannot run.

Seeking your advice on this and let me know the approx price. I can use the existing enclosure, so looking for a 12" sub.

JBL has a GTO 1204D sub which is a 4 ohm DVC.
There is this Ground Zero 400W, 4 ohm DVC which is highly recommended and costs around 5.5k.

You will be happy with 225 watts of power. Try to listen to it first before going further. Or you can go to a shop compare the sound of a 4 ohms DVC sub if you find it better go for it. Like nitrous has mentions two subs.

Which Ground Zero sub is this?

low_bass_makker · 26th February 2008, 01:51

I think nitrous has mentioned the Titanium series sub but they are 4 ohms SVC.

Thanks Nitrous. I checked the JBL site and this model is not shown. Only GTO 1202D which is a 2 ohm DVC. Has it been discontinued and if not, what is the price?

Thanks for the advice LBM. I will try and audition before going for anything.

Also reminds me, Gurus, are there any 2 Ohm SVC's available in 12" and would be great to know the price as well.

If you are looking for VFM then you can go for Pioneer TS-W307 D4. It's available for around 3-3.5K in delhi.

That's not VFM .... that's a freebie .

Guys, JBL subs cost as much as Pioneer subs in the market.

Guys, can you tell me the price of JBl GTO 1204? I cannot see this in the JBL site. Is it still available?

dinu2506 · 28th February 2008, 08:10

No response from anyone? Any feedback from users of JBL GTO 1204 DVC?

dinu, PM Sam. he's the JBL-guy.

I am planning to go in for a JBL GTO1264 sub. This is a 4 ohm dual voice coil sub. It will be wired in parallel to present a 2 ohm load to the amplifier. My query is as follows

The power handling of the sub is 300W RMS. The amp I have (JBL GTO 3501 monoblock) pushes out 360W RMS to a 2 ohm load. Can gurus advice whether this will damage the sub. I don't go to high volumes normally. Is it always required that the sub should be rated higher than the amp.

nitrous · 29th February 2008, 23:41

No, dinu. U won't damage your sub and infact,it is always recommended to have a power of around 10% more than the sub's spec for better quality.

Also, the 360W from the JBL 3501 mono is rated at 14.4V current(as per CEA2006A compliance).Real world conditions(stock alternator in an average car) isn't always 14.4V .ie. less than 360W .
This applies to all amplifiers.
