I bought a dual 12in sub box for 2002 F150 Supercrew. This box has a volume of 1.2 and is sealed is 3/4 mdf and has a sub depth of 8in. I have a Boston Acoustics passive radiator in one of the openings because of the entire internal cavity is open and I didnt want to put two high powered woofers partially because of cost. The other is un wanted distortion. I wanted to find a good woofer that would work well with the passive radiator. The G5 has been discontinued and is getting hard to find. I have found it but would like to use a different woofer. I have a Sony Mobile ES 1000w class D mono amp that is stable to 1ohm. I believe it is a Xm-6001gxd that is with out going out and looking at it. I know the radiator is made for the G5 but I would like use a dual 2ohm woofer making a 1omh load on my amp. I believe the amp puts out 1000watts rms at 1omh and a max of 2400watts. I was wondering if any one had tested the radiator with any other speakers with similar wattages or higher wattages. I know the G5 has a total movement of 3inches and most others dont even put out half of that. Is it Safe to say that most higher wattage speakers will probably work fine because the amout of air it actually moves is less? Wondering if the radiator has been tested to its limits by anyone? What dual 2 ohm sub would work best with this radiator that will fit my box and maximize my amps power outage? Thanks for any info it greatly appreciated
Looks like the correct amp, and it does seem to be 1000W RMS at 1-ohm.
You have to be careful between 1-ohm rated and 1-ohm stable, b/c they don't always mean the same thing, but it looks like you are good here.
Not sure which subs to recommend and I'm not very familiar at all with passive radiators, so I'll let someone else speak to those questions.
Anyone else have suggestions?

Is it 2400watts max? I have lost the manual long ago.
I had a bad link above fixed now - the manual is here, looks like 1200W max at 2-ohms, but max wattage is meaningless anyway.
Thanks for the link so it safe to say it would put out 2400w max a 1ohm, why is max what age meaningless. I thought as far as bass is you could hit max wattage a few times in just one track and max wattage for that surge was important.
Passive radiators are pretty sweet. They serve the same function as a port, but you don't have to increase the box size to above what is recommended for a sealed enclosure. The tuning frequency is selected by adding or removing weight to the radiator's cone. Normally the passive radiator is larger than the actual driver, so i was a little confused why Boston made them the same size. I'm sure they did the math and made it work, since they make several premium products.
You can use pretty much any sub that is designed to work in the same space as your old G5. Pity that it won't match, but it will function the same way as it did before. You're good to go!
2400w max sounds reasonable given the other specs, but it is meaningless.
Look at the RMS spec:
1000W (20 Hz - 300 Hz, 1.2% THD, @1-ohm)
Continuous is implied - also 14.4V is specified above that.
What is the Frequency response and THD for the 2400W number - for how long can the amp maintain that - a few seconds, a few milliseconds, what is the impedance for that?
Spruce (another mod) used to call it the ISL specification (if struck by lightning) - basically it is a spec that amp manufacturers like to quote to make their products sound more impressive than they actually are.
(Same logic goes for subwoofer max wattage - btw).
Hope This Helps!!!
They dont nessaryly have to match because you cant see them any way the box is down firing. Thanks for info.
Okay I understand thanks!
I would also agree with you that they are pretty sweet. Almost twice the bass out put out of one woofer, and tunable like a port. Way better than a port I believe because it really does increase the bass. I wonder way you dont see more of these systems out there.
