Defying Limitation

Extremely high output is not something to be toyed with. The call for extremely high power has been answered by the Hifonics-XX Goliath. A whopping 5000W RMS is output by this amplifier, making it one of the most high output amplifiers available on the market. Only the most capable subwoofers on the market are ready for the power this amplifier can output.

Think your subwoofer is able to handle the Hifonics XX-Goliath’s capabilities? The options don’t stop there. Select Generation XX amplifiers can link together so the audio channels can be controlled from crossovers. This allows you to bridge two amplifiers, towards one subwoofer – resulting in doubled power!

These amps provide what I would call, "LEGIT wattage." No fake sony watts, no miss calculated numbers. This amp will really put out 5,000 watts. Just make sure you have 4 red tops, 3 200 amp alts, new electrical system. ETC. I sure hope you have sum good to put too it ;-) NOT FOR BEGINNERS!

I have been a Hifonics fan and consumer for many years before they bacame a big name. Always top quality and always big power. If you are a beginner - do not think you you are going to just drop an amp like this into a stock charging system - you will have nothing but problems. You must be sure to have enough power within your car to push the amp or you will end up with bad results and a car that oesnt start. I have 2 of these pushing 4 Hifonics Olympus olm-2412's and i actually ended up breaking my rear window before i had to turn it down. It will push whatever you want - and will handle alot of abuse. This is not a little Fosgate or Xplode - this is a big boy toy so take the right steps in installation or have it professionally installed and you will be extremely happy and never get rid of it.
