    • One powerful cap.
I have two sundown SAZ 1500D amps linked together pushing a pair of U series 12s and a rockford fosgate punch P600x4 on mids and highs and it dosnt even phase this thing. The volts never go's below 13, good guality cap.

    • Great product
The capacitor is awesome! Works great. However, The RXD-M5 amp that this was ordered for, is not. And I've not gotten anything from trying to email audio source about it. I've been in constant contact over it since I first installed it because it never was right from the start. So, not really caring for the tech support end of it all, period! ... show more

    • Works good
I like that its not that big and it's not round. I tried others that didn't last. I'm hopeful on this one so far. It's tak3n care of the dimming lights and computer faults.

    • No more dimming lights
Very good product. Running about 1000 RMS and lights were starting to dim. Make sure you put the cap as close to your amp as you can. Would recommend to a friend

    • It does nothing, except flash annoying lights!
It says 40 Farads, which is an insane amount of capacitance, but with 2000 watts of amplifier power, my lights (dash and headlights) dim when the heavy bass hits. Also, when I run it with the floor cover removed from my amp stash, the flashing blue LEDS light up my car at night, which I do not appreciate at all. So all it does is annoy me, and probably drain more energy through the flashing blue cop LEDs. What a wasted of time, money, and precious audio equipment space! ... show more

    • Powerful
I had this hooked up to two competition 12s putting out well over 1000 watts rms. This thing didn't let the voltage drop below 12v at all until it was max volume but it was still going above 11.5 volts easy. Best capacitor I've had in a long time. Hooked up two amps to it just to push the extremes on it. It never went below 11 volts at max volume. Money well spent. ... show more
