[QUOTE="n2audio, post: 8657834, member: 540940"] max power ratings on amps are largely meaningless. Their main purpose is to grab the attention of consumers that don't realize just how little "max" and "peak" mean. There are plenty of amp dyno's on youtube and if you look at the dynamic output vs certified you typically see a 10 or 20% gain, which, in turn, is no where near "peak" power claims by the amp mfgs. Many high quality manufacturers make very little mention of peak/max because they know most buyers in that price range know it's a meaningless number. So -- about your options... RF punch - solid amps, would work great. Actually, the 300x2 is a better fit. EQ - For $140, that amp OUGHT to be accurately rated, but it doesn't look that way to me. A 20A fuse indicates that amp is simply not capable of what it claims. A legitimate 100x2 amp generally has 2x as much fuse protection. Fuse size is not an ACCURATE way to determine power output, but it's a good way to weed out the ones that aren't even close to what they claim. It is relatively safe to assume an amp won't produce more than 10x its fuse protection. So for that amp it would be 200w, and that's at minimum impedance -- 100x2 at 2 ohms. Maybe 75x2 at 4 ohms, I'd bet it's lower than that. Pioneer -- nothing fancy, but plenty of power and would work well. Pio always meets its specs, and 60A of fuse protection is a good indicator of that. Soundstream -- Appears to be over-rated, but powerful enough to do what you need. Physically, it is a TINY amp so if small size is important it is a good option. PPI - They've been putting out pretty good budget amps for a while now. It might not be 130, but it's plenty of power for your speakers. According to fuse rating it'll do what it says, but I believe some tests have shown them to be a little over-rated. Hifonics - Their low lines have been over-rated for a long time now, and the 30A fuse confirms that. It's probably 75 or 80 x 2. Planet Audio - One of the leading junk brands out there. 20A fuse. it's probably 50-60 x 2. [/QUOTE]
