Can i bridge my JBL GT5 A3001

[Lauran]

Hi guys,

I've just bought a JBL GT5 A3001 amp together with a Ground Zero GZIW 300X subwoofer.

According to JBL the amp is mono. This makes senses since these are the watt ratings of the amp.

175W RMS x 1 channels @ 4 ohms

225W RMS x 1 channels @ 2 ohms

300W RMS x 1 channel @ 1 ohm

The subwoofer is 4 ohms so my amp would deliver 175 watts according to JBL.

But what I don't understand is that the amp has to times a plus and minus speaker output.

But the ratings say x 1 channels @ 4 ohms.

Does this mean that the amp will deliver 175 watts when the sub is bridged?

Or will it then be 225 watts since the resistance divides itself by two when bridged.

Or can't I bridge the sub and do I have 2 channels with eacht 175 watts.

I hope my question is asked a bit understandable.

I'm not very experienced with this so therefore this question.

Thanks!

It has 2 sets of hookups to make it easier to run more than 1 sub. If it sub is 4 ohms that is what the amp will see

A lot of monoblock amps now have two sets of terminals. As was said above, that's just for convenience. The amp cannot be bridged and the sub is a single voice coil 4Ω sub so you can only ever present a 4Ω load to the amp with that sub.

So if i bridge the 4 ohm sub it will see an 2 ohms sub and i will have more power?

I understand it now.

Thanks for the quick response! //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Let me verify because I'm not terribly familiar with that sub... is it a single or dual voice coil sub?
