If I connect the Sub in Amp Bridge mode, should I need to give stereo input or Mono input will be enough to bridge 2 channels?

Which Amp do you recommend for this sub? I have two - JBL 1004 and JBL 75.4?
In bridged mode, mono input is sufficient, but it is better to give an input to both channel, but using a y connector etc.

Tricky question - I am guessing both will sound pretty good in bridged mode with a sealed sub. The 75.4 simply was my favourite amp.
But the 1004 has more power, which is better for the sub.

Cut off at about 100HZ, bass boost off and bridge it to the 1004 and adjust gain to taste.

But sam, i am just deriving the .1 from my rear channels. Means I am routing rear+bass to 1004 now. Then I use HPF for Rear. Then I just pass the Aux out of 1004 Amp to 75.4, there I am LPF for the sub Bass.

So currently 2 RCA inputs for the sub. But I have a switch in 75.4 which is in "MONO" mode, Can i change it to "STEREO" Mode?

So Can I use the 75.4 to power the 4 component speakers and 1004 for Sub. (Now its routed completely opposite). Do I find any big difference or let it be like now.

But sam, How do I exactly know 100hz in the amp? Its marked only for 32HZ to 320Hz. Any guidance?

This would be better. The smoother 75.4 for the components. And the 320 RMS for the sub.

The 1004 and 75.4 are both 4 channel amps. If you are using either of them bridged to drive a sub you will get 2 bridged channels each of which is not recomended to drive an impedance below 4 ohms. So your sub should be either a 4 ohm DVC sub (2 4 ohm coils) or 2 SVC subs of 4 ohms.

I have not compared the 1004 and 75.4 against each other but I do know that the 2 bridged channels of the 75.4 can drive a 12" JBL 4ohm tube to very high sound levels (the tube is an efficient but boomy woofer system). Given the nominal difference in the power rating (in db) between the 1004 and 75.4 I would advise you to use the 75.4 for the sub(s) and the more modern 1004 for the front and rear.

Which sub(s) do you have now?

Investing in a sub also means that you have to invest in the space (sub's box) for installing the sub.

Exactly. So I should better buy a 4 ohm DVC sub (2 4 ohm coils). Which sub do you recommend for this? Is it possible to get one under 10k?

Yes it is possible to get a super sub under 10k. Recently id had come up with their entry level sub CTX series and i was in love with the sub when i first saw the pic.

Pics can be deceptive.. one needs to audition it to understand how it performs!

I am sure this sub can leave behind many good subs under 15k price tag and for the looks had never seen such a good sub (built quality) at the price it comes at.

Under 10K you might be limited to Pioneer.

IBM_J wants DVC not SVC. If you are keen on GZ the one I'd recommend is the Uranium 12X. It is DVC 4 ohms each but I guess it is more than 15K retail so does the JBL Gti MKII.

Sir, Sorry to correct you here but now there are many good options available in the market under the 10k mark.

Sir, my humble point is.. you're making all the tall claims only by looking at the pic?
