Which Amp for GZ RW 12 XD-AL Sub

[abhinav.gupta88]

Hey people

I have decided for the following sub

GROUND ZERO

GZRW 12 XD-AL
30 cm 500 watts, cast basket, 2 inch 2 x 4ohm, Alucone, woven in leads, Xmax 18mm, SPL 91,4dB

What i wanted to know is that

Is the following amplifier ok to be fitted with this sub without any problems ( low bass or distortions or disturbed bass)

JBL 301.1

• 204 watts RMS x 1 channel at 4 ohms and ≤ 1% THD + N (BR>
• 294 watts RMS x 1 channel at 2 ohms & 14.4V supply and ≤ 1% THD + N
• Signal-to-Noise Ratio: 77 dBA (reference 1 watt into 4 ohms)
• Dynamic Power: 320 watts at 2 ohms
• Effective Damping Factor: 6.39 at 4 ohms
• Frequency Response (–3dB): 10Hz - 302Hz
• Maximum Input Signal: 4.7V
• Maximum Sensitivity: 220mV
• Output Regulation: .098 dB at 4 ohms
• Dimensions (W x H X D): 11-5/8" x 12-5/16" x 2-3/8"

Because My ICe with the 601.1 is going a bit out of budget so have to decide for it.


Please Gurus , Help Me out

if the sub is doing 91db/1w/1m it is pretty efficient. at 100W it will be 114db. I am sure this will be more than adequate.

Bass & Trouble represents GZ so it would make sense to PM him.

Navinji, how is this calculation done ?

for power it is 20 log P2/P1

[adityamunshi]

Still not getting it, what do we substitute for p1 and p2 ?

[navin]

depends; in this case it is 20 log 100(W)/1(w)

[low_bass_makker]

There are lots of amp in the market today what is your budget ?

I am using the same GZ 12XD-AL Sub x 2nos. powering up with a 2ohms stable Assembled amp Bridge mode on DVC mode,man its kicka$$ and very loud,i know if i plan to install a 2 x monoblock it can power up more.

As LBM described whats your budget as there are many amps available in the market to power up the subwoofer

[abhinav.gupta88]

See The amps Sub will be around 12000
the JBL 75.4, around 8k
illusion components 6490
so my budget now lies around 13500

the 601.1 is a bit higher priced than this.

[abhinav.gupta88]

the 75.4 will run the components etc while the 301.1/601.1 will power the sub

[low_bass_makker]

If you are planning to add only fronts then you can run the sub with a 75.4 only. No need to get another amp.

[abhinav.gupta88]

Well actually i was thinking to keep the front ones stock and replace the rear with components and run those along with the front and mids with the 75.4

So want to keep a seperate amp for the Sub

[low_bass_makker]

If you want to keep the front stock then run them through the HU. And wire the rears and the sub through the 75.4

Navin Ji he is powering 4 inch full range drivers from 75.4. Which will be over kill for a 4 inch driver thats why I recommended to run it thorough the HU
