Hi Lecram, At this point, I have put $4,000.00 recently into the inside of my 700cx, very well worth every penny too, and I am going to ride off into the sunset with this amp, it's all new, with modded capacitors and tweaked power supply, I might put the SR reds fuses inside, another $400.00, I am conterplating If there is a need?, also if you put a single pole 30 amp breker on this amp, play for 17 to 20 hrs for burn-in, you will be amused at how much better a 700cx sounds and runs extremly cooler doing this, when you do this 30 amp breaker, have a furutech GTX-D Rhodium outlet on it, these wpo's take 500 to 700 hrs to break-in, however, after 165 hrs, you will enjoy the sound, the wpo opens up a bit to enjoy, and the the furutech GTX-D R does not warm up or get hot with this much current like most wpo's do,best $5.00 that the breaker cost that I ever spent in audio, I would have paid $300.00 for what $5.00 did, it's a win!
