I was just looking on Ebay for amps and saw an Earthquake amp about 5 feet long advertised at 6000 watts RMS for $600. Now whats going there? Also, what does RMS stand for? And how does Sony make a 1200 watt amp and sell it for like 400 retail and 180 on Ebay? Are these amps just way over rated or do they actually make that wattage and then lack in another part of the amp? Too many questions. Is there an exact match for amp wattage and speaker wattage? EX: do I put a kx1200.1 (1200 watts max) on a sub that handles around 1200 watts max? Sorry for all the questions on one thing, any input is appreciated ------------- Thanks

A case of do you believe everything you read. RMS = root mean square. Friends don't let friends buy Sony. The best way to match equipment together is to learn about it so you can make an educated and informed decision. Ask questions, no matter how stupid they may sound, we've heard pretty much all of them before and usually the answers are all the same.

What does Root Mean Square mean? Are these algebra terms, I suck at algebra.

RMS power can be thought of as the average continuous output an amp can generate without exceeding its heat ratings. Most amps list "peak" ratings. Peak is the theoretical maximum excusrion the amp can hit for a very short time within the listed noise ratings. Peak ratings are mostly meaningless for choosing equipment. RMS is what you will use in everyday listening, and in general an amp with higher RMS ratings than another will also have higher peak excursion capabilities. Earthquake amps are pretty good quality and their PHD4 is a mono sub amp that is indeed rated at 6000 watts PEAK into 2 ohms. If you can get this amp for $600 buy it now, as it retails at around $2799. I agree with forbidden, do not waste your money on Sony equipment, unless you are buying a TV for your house.

Another thing to keep in mind is that your amplifier can only produce as much output as your charging system can supply. For example, if this amp is rated at 6000W peak, theoretically it will produce 3000W RMS. If this amp does indeed give you 3000W continous power, it will take a MINIMUM of 300 amps to produce 3000W of continous power, and this is only if the amp is efficient (The majority of high-end amps on the market draw 10 amps of current @ 12.5V for each 100W or continous power, lower-end can draw even more). So, if your looking to get all that power from your amp, your will need a bigger alternator (Most stock alternators produce 70-120A) and an array of optima yellow tops if you plan on parking it... So before you make an investment like that consider the amount of money your going to have to spend on an alternator, 1/0 power wire, batteries, distribution blocks, etc, etc... It can add up fast (Especially if your not installing it yourself).

Sometimes what happens is a distributor may offer a retailer a price break if the retailer buys so many units. If the retailer doesn't think he can sell that many in his store, he may buy them all anyway to get the price break, and throw the ones he doesn't think he'll be able to sell on eBay for a reduced price, sometimes as low as what they cost him. This "selling out the back door" was very popular in the early days on the personal computer. You saw a lot of IBM PC XTs sold this way. Some manufacturers frown on this, and almost consider goods sold this way to be "grey market"
