I have 2 but they cut off once bass hits hard. What could be the issue. I have a 2 channel 1k watt amplifier hooked up bridge.

Are you running them at 1 ohm or 4 ohm? If at 1 ohm is your amp 1 ohm stable when bridged. If not then you need to run them at 4 ohm bridged. That may be the problem. You can look up wiring 2 subs online. Rockford Fosgate wiring wizard is great. Hope that helps!

If I bought 2 to put I’m my car what amp would you recommend? Putting out 2400w.

Bro, lawsuit or not, Rockville RXM-T2 or RXD-T2. They are the exact same specs, only the RXM is silver/blue & RXD is black/red. For $139.99 2200 max 2 x 400 RMS @ 4ohm 2 x 800 RMS @ 2 ohm 1 x 1200 @ 4 ohms bridged. (Not bridgeable @ 2 ohms, tested by Derek Williston aka D-Wiz) Wound up blowing a set of Pyramid 12s (only 350RMS) & got the 1200W, DVC, 2 ohm Skar 12's installed yesterday. Bridged them to 4 ohms in series, & literally cannot believe the power. I had to get a capacitor, went with Audiopipe Stiffening, 3.0 Farad. The amp is #1 on Williston Audio's "Amps that don't break the bank", not to mention the specs are about right for this little set up.

How big is the magnet? And what amp would go good with a pair of these? ..

I'm not sure about the magnet, but I have 2 of these running on a 1200.1 rockford fosgate amp. It puts out a little over 1200watts rms which matches 2 of the subs

I have a pioneer GM-A6704 amp would this be enough juice? 1000w max, but can only be bridged to 2 channels (i think) about 200 watt rms

Honestly, no. Keep that amp for your mids if you like it, but get yourself a descent monoblock for the subs. The Pioneer is severely underpowered and it's a class A/B.
