After what seemed like months of searching for the perfect Class D amplifier, I got frustrated, so many too choose from, I knew exactly what my subs needed so I contacted Sonic. Rob R. was a great deal of help with making my final decision and ultimately purchase. This amp is very user friendly, even if you don't know what you're doing, the detailed instructions that come with it should help the newest of noobs. Love the clean clear rumbling bass I get out of the ZRX1000.1D. Before my purchase I knew nothing of Hifonics, now I'm in love. Sonic Electronix is tha shiznit, will be purchasing all my car audio needs (wants) from this site, from now on. If you're in need of 1000w RMS DO NOT HESITATE...... order this amp. You will NOT be disappointed!!!

I have had this amp for a couple of months and I was running it at 4 ohm on a Kicker 12 single voice coil sub and it sounded great. Then I bought a Sundown Audio E 12D2 and now it is running at 1 ohm and boy did it come to life. I am very satisfied and I will buy Hifonics amps in the future.

I got this to replace a crunch I had powering two kenwood 12s in a ported box and even though its rated at 750 rms at 2 ohms my two kenwood have more than enough power going thru them rated a 400 rms each can't wait to put two more to run it at 1ohm smaller kenwoods though to match the 1000 rms perfect!! King kong in the trunk!!! Love hifonics and I apreciate sonicelectronix very much!!!! The durability is still a question it's only been a few weeks but it's been AWESOME!!!!!

Very well built, beautiful amp. I would highly recommend this to anyone. Pushes an 8" L7 too well.

This is a great amp would buy again great price!!!
