Default Re: JBL branded HU? EDIT: GT-X555 & 333 Confirmed!

I am planning on a GT-X333. Can this HU drive speakers by itself or Will I need an amp?
Does it come with an antenna for the radio or do I need to buy it separately?

Thanks

You Don't need an amp. You need to buy the antenna seperately.
mine costed 150/- for fiat punto.

Before installation of GTX333 on my car, I listened to music on 3390 in the shop as 3390 was my first priority before i went to the shop. 2 minutes of listening to music on GTX333 changed all that. Go for JBL, you will not regret it.

Thanks for the input certainly helps the cause as most of the dealers confused me between the two.

I have used a 32GB and it worked fine. I think there is no limit on the SD card and USB pendrive, so long as the current draw is the same.

You will not need an amplifier to drive speakers. You can choose to install one, but you are not obliged to.

You will need to fit an antenna or plug in the one that comes with your car.

I'm guessing the HU would easily be able to run GTO608c components without any amp however the website doesn't mention about its driving capacity anywhere. If you could share it please?

Is there a limit on the number of songs on the drive - like maybe 999?

The unit will run a set of GTO608C with ease -- however I would always recommend you run components off an amplifier, as the amplifier inside ALL head units has limited capabilities.

I think it is 999 per folder. I'm really not 100% sure, I'll check.

Does it do sub folders like a Artist\Album\Song folder tree. I suspect it will max out at 999 songs regardless of the folder tree.

So you cant do 999 albums for each artist or 999 songs for each album.

Default My I10 -- JBL 333 out and Alpine CDE-100EUB in!

Readers on this thread may be aware that I was an early customer of the newly launched JBL GT333 head unit here in Goa, when I had it installed on my I10. While the HU was great for its price, I felt let down as it could not play random songs within the folder of the USB pen drive or SD card. It would only play random songs across all folders.

It so happened that I needed to install a head unit on my Alto LXI and I decided to buy a new Head unit for the I10 and place the JBL 333 on the Alto. I checked up with my accessories dealer at Porvorim and he advised my to put the Alpine CDE-100EUB (Rs 7200) for the I10.

The installation of the CDE-100EUB was a breeze since I only had to remove the JBL 333 and replace it with the CDE-100EUB. I noticed one major plus: The trim plate of the CDE-100EUB fitted perfectly within the slot provided for the head unit. The JBL 333 trim plate did not fit in the slot and I had to use the HU without the trim plate. This had given the JBL 333 a rather crude look. So Sam, it appears that the JBL 333 does have some fitment issues with the I10.

As soon as I inserted a pen drive on the CDE-100EUB, I was really pleased that the CDE-100EUB could play random songs from within a specific folder of the pen drive and not across all folders, like the JBL 333.

The controls of the CDE-100EUB are quite simple and effective. The CDE-100EUB does not have a 3-band EQ (it only has a 2-band EQ) like the JBL 333, but more importantly, the CDE-100EUB serves my purpose extremely well. The JBL 333 is now doing its duty on my Alto LXI.

The 100EUB is designed for those who have no intention to add amplifers and subwoofers to their car stereo. The 333 sacrifices the CD function but includes 3 pre outs. That said I do believe the 333 USB search facility can do with an update.

Random songs shiould be within folders just like an ipod does (only Apple calls them play lists).

Kenwood x994 / 8016 does random, but with a peculiarity. It works with iPod/iPhone, but not with "USB" - pendrives and HDD (at least I haven't found the setting to do that)!!! With iPad/iPhone, one can set the amount of randomness as a %age.

Thanks Guys.

I am planning to install a pair of Rockford Fosgate R1652S components in my Gypsy. @40W RMS continuous, I suppose the HU rated @50W RMS should mange decently (provided the specs are not bloated).

Does this look like a good pairing? Remember that the soft top will not provide an enclosure for the speakers like a metal bodied car, so will they sound bass anemic? The speakers will be mounted in a space cutout provided above the footwell and below the dash.

Or should I go for a bass heavy system to compensate for lack of sealed enclosure so it sounds more normal in a soft top environment?

One way to work around the random sorting problem is to keep some 32MB or 2 GB SD cards, one for each genre, locked in your dashboard closet. You can recycle your old Camera SD cards if you are planning to get new high-speed ones with larger capacity.

Is it possible to upgrade the firmware on HU 's? Do HU vendors provide firmware updates? Is it possible that the sorting problem will be fixed in a firmware update?

Thanks again!

Ok what I am about to post might have all the professionals in the industry wanting to put a supari on me.

I have tested (I mean bench tested) atleast 20 HUs (between 1984 and 1995) and this were the years when they made HUs out of steel not plastic (oldies know what I mean).

NOT ONE HU was able to deliver more than 20W rms x 4 channels 4 ohms(I used 4 x 4ohm/1mh resistive-inductors to simulate an reactive load) 20-20kHz with less than 0.1% THD. We tested Alpine, Pioneer, Kenwood, all major brands. And this was with a bench supply of 14.4V (the bench supply could deliver up to 30A before being stressed). With a more typical 13.5-13.8V you will find in a running car I don't expect any HU to delvier 50W rms x 4 channnels @ 4 ohms/channel (reactive) 20-20kHz, THD < 0.1%.

That said the difference between 10W and 40W is only 6db.

Now for the open air question. Yes a rag top will leak bass. However I do not recommend trying to compensate using big subwoofers. Use a subwoofer by all means but the bass leaked by a rag top is more than what a subwoofer can even partially compensate for. The subwoofer (depending on your expectations) might just make the music more listenable. I would suggest making one with a hump in the mid bass (60-90Hz) and forgetting about the sub 40Hz information.

HUs these days are all rated @ 50*4.
DOESNT mean they give out 50*4 w of RMS power. They are rated @ PMPO or Max/Dynamic power output, so their figures don't sound puny. 50*4 is marketing pitch. Power rating itself is more marketing pitch than a gauge of an amplifier's performance. That's my belief, though. Not influencing anyone on that.
It's more like 8-12 w RMS, and that too, when powering 4 channels, even 12*4 is out of question!
