Subs are getting here today and I just ordered a hifonics brutus mono amp the specs are
400watts at 4ohm
900watts at 2ohm
1200watts at 1ohm and all of those are rms wattages this is one kickass amp.

Im running hifonics Thor I bought in 1988! I have dual voice coil 4ohm Polk with the voice coils parallel putting it at 2 ohm, with the 2 channel amp bridged. It absolutely cranks. I love hifonics

Pyramid,,, are you kidding.... What happened to Rockford or JBL or JL.... Just realize a pyramid amp is not going to run 1000 watts ever at 12 volts.... If you dont believe me look at the fuses in it probably 2 10 amp fuses... Amps x volts = watts 1000 watts requires it to draw 83.33 amps... so to answer your question no you have nothing to fear, I am sorry if I seem somewhat put off by the amp but I used to own a stereo shop and did $5,000.00 installs daily... If you want a good sound and quality music you have to pay more than 99.00 for a 1000 watt amp....RMS Power vs. Peak Power
The amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds. When choosing an amplifier, the RMS rating is the power rating you should pay most attention to.
Also, keep in mind that some manufacturers calculate the RMS power ratings of their amplifiers at different input voltages. For example, an amplifier rated at 100 watts RMS at 12 volts can produce considerably more power than an amp rated at 100 watts RMS at the more typical 14.4 volts.
Stereo manufacturers often display peak power ratings on the face of their products. The peak power rating tells you the maximum wattage an amplifier can deliver as a brief burst during a musical peak, like a dramatic drum accent. The RMS figure is more significant.
RMS Power at 2 ohms
This spec tells you how much more power your amp delivers when presented with a 2-ohm stereo load. You can achieve a 2-ohm load by using parallel wiring or by using 2-ohm speakers.
Theoretically, amp output should exactly double as the impedance drops from the usual 4 ohms to 2 ohms. However, amp makers use different degrees of regulation on power supplies, which can restrict the actual increase in output.
Less regulated power supplies come closer to doubling their output into 2-ohm loads. An amp with little regulation can achieve higher wattage into lower impedances. An amp with stiffer regulation maintains rated output from your amp as other electrical accessories demand voltage from the battery. In the final analysis realize cheaper has to be cheaper for a reason and although there is a point diminishing returns that spending does not gain enough to make it worth it... (doubling the price only gains 20% better sound)... Just my opinion sorry.....

I know all about peak vs rms. different power at different oh, loads, that's why I bought a brand new hifonics Brutus mono amp
I'll be running my subs at 2ohms and the amp pushes 900watts rms at 2ohms, both the subs together are 800watts rms so I'll be in the ideal range. The amp has 2 70amp fuses so it can handle way more power.

Like I said im a fan of hifonics, I've been out of the game awhile but back when I was doing audio completions it was crazy the difference In real power output between different brands. Pyramid, Craig, Jensen and other would but crazy big numbers on the box like 1500 watts but only have a 20A fuse while competition brands would do the exact opposite so people could stay in there power class while getting more " it's only 250 watts" but it has a 60A fuse cause the 250 is like 0 thd at 8 ohms or something silly. Whole thing used to make me laugh, bottom line always look at the fuse to figure out what the amp will really do.

Well the new amp got here a few days ago, again its a hifonics brutus mono sub amp.
450rms @ 4ohms
900rms @ 2ohms
1200rms @ 1ohm
The amp is a single channel but it has 2 mounting point for wires so you dont have to jam speaker wires together. Im running my pioneer 12inch TS-W309d2 subs independently at 4ohms 450rms 1400 peak in separate 12inch ported boxes. Will post pics today. The subs hit and i mean hit like someones punching you in the back, and all the girls wanna sit in the back if ya know what i mean.
This is the only pic of the amp i have on my phone at the moment ill go take more of the rest of the system installed today.
