Hi everybody

I would need your help because i'm kind of confuse

I already have one pioneer Ts-308D4 DVC 4ohm 400W rms
And I would like to buy another so I could play both together

Now I wonder what the power of the amp should be so I could get all the amp power ?
I'm willing to buy hifonics which I find really cool
those are some hifonics: Hifonics HFi1500D Hifonics Brutus BRZ1200.1D Hifonics Brutus BRZ1700.1D

Thank you in advance :)

If getting a second woofer, your wiring options will be 1-ohm, 4-ohms, or 16-ohms.

You will beed an amplifier rated for around 800 watts into any of those loads. A little more is better than a little less.

You're gonna want an amp that will do anywhere from 800-1000rms @ 1 ohm. One that will do that amount of power @ 4 ohms is gonna cost you a pretty penny, but will allow you to have more power on tap should you ever decide to get better subs that can take whatever the power that amp can do at 1 ohm.
