The results can be all over the place. For speakers which can accept 2 amps (4 speaker posts) what is the generally accepted fact as to the set-up which yields the best sound. Dropping all that energy out of the main amps and main speakers is a real boon. It is basically considered, that if you have the extra amp sitting around gathering dust, why not biamp, it will only cost you the added expense of speaker cables. So I finally purchased the Classe CP 800 preamp/DAC and Classe CAM 600 monoblock amps to pair with my new B&W 800 D3. Review By Rufus Smith I was reintroduced to Audio Research around two years ago when I had the opportunity to review the outstanding LS28 / VT80 combination for Enjoy the Music.com.In the past, I have found Audio Research's amplifiers to be very analytical but somewhat sterile sounding. If your head unit has an RCA out you can run the sub amp off that and connect the speaker cables to the 4 channel amp and set it to high level to run the speakers. Most of this amplifier is specially built into the receivers that have so many channels such as stereo amplifier, which works both the right and left channel signal, while some of them are single channel only. For speakers which can accept 2 amps (4 speaker posts) what is the generally accepted fact as to the set-up which yields the best sound. or just my stand cable 2. A differential monoblock uses the black connector on the amp’s speaker terminals to actively pull the inverse or differential of the positive (red) terminal’s output. Usually, this form of mono amplifier can be used to produce the power to a single signal speaker, the subwoofer can typical generate low frequency sound, which could be felt as much as heard. Call your amp manufacturer and ask them if you have questions about what you own. The amps will come with the gain set, it is not adjustable by the user. The little Channel Islands recently reviewed might make an interesting choice with their very good sound and small foot print. That is, two speakers is double the load of one speaker. Thank you everyone for the responses. An old guy with hearing loss, like me, may want to run the tweeters a little hotter to make up for all my time on rifle ranges while in the military. Thank you. If you want to use the amp with the higher gain for 4 ohm speakers you can, but you have to ensure no voltage above 3.75Vrms (~170W) on the input. You can wire two amplifiers, or even multiple amps, in one car audio system, but it takes some extra planning. This is a valid question, but not easy to answer as a rule. Actually, the couples of subwoofers can be wired together in order to form a single mono amp for obtaining the most effective performance.

However, most of these amps work on couples of various channels with two various input signals. Estimating amp power at the odd impedance values: 8 ohms — figure on the amp putting out half the power it would at 4 ohms Kenwood KAC-9106D 2000 Watts Peak/1000 Watts RMS Mono Block Class D Car Amplifier with Speaker Level Inputs 145. price CDN$ 132. I would not believe that the overall sound would be much different if both amps were solid state, pretty much Kal's point. Is it using 2 monoblock amps to power each speaker or is it using 2 amps which are 2 channel each and having each amp power the "lower" set of speaker posts in both speakers and doing the same with the other 2 channel amp for the "upper" set of speaker posts. One of the greatest benefits of monoblock amplifiers is providing the top most quality sound. Is it using 2 monoblock amps to power each speaker or is it using 2 amps which are 2 channel each and having each amp power the "lower" set of speaker posts in both speakers and doing the same with the other 2 channel amp for the "upper" set of speaker posts. Parasound and others make some very interesting choices as well. On the other hand, if money were no object and I found an amp that I really liked, I wouldn't hesitate to buy two and go the monoblock route, but I would have to like the amp in the first place. vs Monoblocks-Need Help Please.

You can wire as many speakers are you want by combining series and parallel connections to maintain a safe impedance but you can run out of power since … Usually, this form of mono amplifier can be used to produce the power to a single signal speaker, the subwoofer can typical generate low frequency sound, which could be felt as much as heard. "Active" biamping (which is considered true biamping) is a completly different approach, however your speakers need to be properly wired for this approach, and an external crossover needs to be employed between the pre and power amps. Then again there are those who swear by the improvements and only you can be the judge of what you hear. Digital crossovers can be under $500 but some people may be scared of digitizing everything. Newbieeeee ?? Let me then ask the question this way. Levels are set with the gain no matter what you have connected to the amplifier. The monoblock amp can generate a single power signal and it is ideally matched to the low frequency design of a subwoofer. Do you know how do vinyl records are made. If the impedance is too low the amplifier has to provide more current. To turn the amplifier on: connect your speakers, con… But the added expense of purchasing an additional amp and cables for the purpose of "passive" biamplification generally does not render the sonic rewards for the cost of the investment.
