amp for 2 x JBL GT5-15's

[juzzyx]

Hi,

I want to buy 2 x JBL GT5-15 subs. Each sub can handle 300rms and 1200watt peak.

My amp puts out 600rms and 1200watt peak (Pioneer GMD8500M). Will it be enough to power these subs?

Thank you.

Now I have an absolute noob question. If a monoblock amp that is rated at 300wrms @4ohm is hooked up to two subs rated at 300wrms @4ohm.
Will each sub get 150wrms? I am so sorry for this question btw hahaha

Kieran, you can only connect a second sub to your amp if it is stable at lower than 4 ohms. One sub on it's own will produce a 4ohm load to your amp,(unless your allready taking into account the voice coil configuration that gave you 4ohm)

A second sub will bring the load down to 2 ohm. Most mono block amps though should at least be stable at 2 ohm, what amp do you have?

Otherwise so long as the amp is presented a suitable load, the power will be divided equally between the subs.

Thanks guys.

So, don't go for the peak rating. At my car audio shop they only talk peak wattage, thought i would ask people who aren't after my money.

My understanding of peak value is that it is estimated by the manufacturer.

So you just need to cover the rms rating of the sub.

Ryda are selling these subs at the moment for $148 each

Power isn't always relevant as music is dynamic, the subs will run with 5 watts, they will also run with 5000 watts, it's entirely up to you and the application.

Thanks HCVP. It was more of a, "for later on down the road" type question.

Thanks HCVP. It was more of a, "for later on down the road" type question.

Well it would still help to know the model number of the amplifier, because like i said most, if not all, mono block amps will run at 2 ohm. There's not many applications where they are set up to run at 4ohm.

It's an MB quart Onyx 1000D mono, rated at 475wrms @4ohm, 750wrms @2ohm and 1000wrms @1ohm.
It will be amping 2 JBL GTO1214 single voice coil subs, they're 350wrms @4ohm.
So this means the subs would be getting 375wrms @2ohm each?

[MAG00]

That's correct.

Hooray, thanks guys, kinda hijacked the thread a bit hahahaha
