Finally upgraded to a SRX718S Sub!

I have 2 amps on hand for this sub.

Crown XTi2000 or Mackie FR2500

When i hook up either amp bridged and crank it up the cone sounds like it distorting right before the amp clips. Seems as if this is too much power for the sub which it cant be. This sub is rated at 3200 watts peak. My JBL MRX528S never did this on either one of these amps. I could clip all day and push those things hard and never would never distort or sounds weird.

Crown XTi2000 bridged at 8ohms is 1600 watts which is 100% of RMS

Mackie FR2500 bridged at 8ohms is 1500 watts which is 95% of RMS

The MRX528S was at 100% RMS at 4ohms 2000 watts on my bridged XTi2000 and sounded fine.

These subs need a break in period or maybe it's defective from JBL, i have no clue. Either way i brought it brand new from a JBL retailer.

It sounds like a question for a JBL forum!

I am driving my two VRX918S (same as SRX718S) with Crown itech8000 in bridged mode without any problem. return your subs for checkout.

The XTi2000 is a good amp for this sub.  I would contact JBL Pro since you're pretty sure the amp is working ok.
