We should be very thankful that we are born in this modern generation because of the existence of the Internet. With the Internet, every information (whether about Pre Amplifier) or any other Pre Amplifier can be found with ease on the Internet, with great articles like this.
Is it safe to buy something off ebay like a violin bridge ?
I want to buy this off ebay http://cgi.ebay.com/4-4-Electric-Violin-Bridge-Pickup-Amplifier-Pre-amp-/110557750328?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item19bdc16438But Pre Amplifier i never got anything off of there before so i don't no if it is safe or not.What do you think ?

Best bet is justr to try both. THeory is no sustitute for practice.
preamps are for sound. they jack up the wattage to your reciever. Carver is actually nice piece of muscle.. you like to crank up the tunes that one will rock your sox off
A Kicker amp with the same RMS wattage as the two subs should be a good choice. Some people say run a stronger amp.. just don’t blow the subs! Others say use a less strong amp.. so your subs should never blow. Try to find what sounds and works best for you.. and you will be satisfied. Does this help any?
A surround decoder accepts signals from an analog or digital source and decodes the signals into individual channel information. The channels can then get routed through a pre-amplifier for conversion to analog from digital (if not analog already), for volume control and other functions such as bass, treble, etc…, and then go to the amplifier to be amplified for speakers.A pre-amplifier can have a surround decoder built-in and the newer ones typically do. FYI: An A/V receiver usually does all three jobs: surround decoding, pre-amplification, and finally amplification.
The way you are phrasing this question is kind of confusing, BUT, if I’m reading this correctly, you have a Yamaha HT Sub, which you would like to swap with a JL W7 10″, the obviously issues you will face are going to be the Volume of the enclosure, the power limitations of the Amp, and the drastic sensitivity variance.I would recommend building a new box right off the bat. You can try to mount them in the yamaha enclosure, but you might actually damage the sub, since the small enclosure is going to force the natural resonant frequency of the box to much higher than it would normally be, meaning that the sub’s peak might lay somewhere close to 80hz, which means the impedance around 80Hz will be much higher than it should be, which can cause the amp to push a clipped signal through the sub, which can damage the sub pretty quickly.As far as the impedance is concerned, you’ll have to wire the Subs dual voice coils in series, raising the resistance to 8ohms, which should be right on par with the amps rating.The amp is only rated for 100w (assuming rms), and because the sensitivity of car audio equipment is significantly lower than with home audio equipment (car audio speakers are heavier, and have thicker surrounds and spider structures), so you will not be getting the same volume out of the W7 as you would have with the standard yamaha sub.So you really have to decide whether its worth it. If the yamaha sub isn’t blown, I’d say leave it alone, and use the JL for something else. if it is blown, you can certainly switch it out, but for the time you are going to spend making it work, you might just want to invest in a new home audio sub.**I think you were also saying you want to try to run it off a second amp. DON’T!!! You never want to run a speaker of two different amps, this causes all kinds of problems, the least of which is alot of smoke and sparks :-/
What someone says you need something so you immediately go looking?You don’t need a preamp. Every guitar amp has its own preamp already built in. If it didn’t, it would just be a power amp. Like this: http://www.hartnollguitars.co.uk/products.asp?id=3086 . For that you would need a preamp.That said, if you want a preamp, you can add one. Whether Marshall, Boss, or whoever.
nitric oxide in simplest terms is a gas that is produced by certain enzymes in your body. One of the greatest areas where nitrous oxide is created and given off is the endothelial cells lining the inside of your blood vessels. This may give you a ‘relaxed’ feeling as it may possibly lower blood pressure. It is a relatively new topic of study and may affect heart-rate in different ways and varying doses. Of course this is not limited to anywhere in your body, nitric oxide can affect all areas, mental, muscular, heart, etc etc. For better or worse.The worse part …is that nitric oxide given off by these endothelial cells primarily relaxes smooth muscle surrounding the blood vessels and works in tandem with prostacyclin, inhibiting the binding of platelets in what is called the intrinsic coagulation pathway (response to internal bleeding). Basically, nitric oxide, along with prostacyclin, is given off in the blood vessels to stop platelets from binding. If any internal bleeding occurs, this process is halted in the localized area.Be aware that high levels of nitric oxide circulating in the blood (up until a few hours …mabye 6-8… after taking these drink supplements) will stay high, leaving you susceptible to internal bleeding if something drastic should ever occur. The vascular spasms which are needed to initiate or progress coagulation from internal bleeding, would be highly inhibited with the unnatural levels of nitric oxide signal circulating in the blood causing vasodilation where vasoconstriction is needed.Serotonin begins the process by which endothelial cells create nitric oxide. Serotonin is also taken up by platelets at the site of a vascular injury. This is an important hormone which controls levels of vasodilation and constriction at certain times as well as an important signaling molecule (you may have heard of it used as an anti-depressant etc). When serotonin is taken up by platelets, and high levels of nitric oxide are still creating enlargement of the blood vessels, you have a serious problem.Nitric oxide shouldn’t be used for those with abnormal heart-rates or blood pressures. If you have any anemic or blood conditions I would not recommend this. Most athletic types who use it will likely never experience any problems. In my opinion, I doubt any serious long-term effects will arise with the use of nitric oxide (of course anything in excess can hurt). I would not be surprised to see if there are serious side effects from abuse as research and studies become more accessible and available. Short term effects with large doses however are somewhat frightening
