How do I hook up my Boston Acoustics to my Mac Mini

Depends on what wattage is of the BAs. You will have to preamp the mini and then run to an amp and then to the speaker.

Boston Acoustics CS26 Speakers sound cuts out for over a second at higher volumes tested using two different amplifiers same problem. Does not seem to be related to amp distortion:clipping protectio

It sounds like the speaker cones(if that is what they have) get hung up against the back of the case. No vibration=no sound. Check to see that there is no hum adding to the pressure on the speakers. Check to see that the speakers are hooked to the correct impedence output of the amplifier. Also, wire length affects impedence and shortening the wires might help.

I tried hooking up my boston acoustic soundbar to the tv's audio inputs, but i get nothing. if i hook it up to my dish receiver i get sound, but i cant use my bluray, cause its hooked in the receiver. why...

because your tv output is not of suffieient power to drive the soundbar. The soundbar needs to be hooked up to an amplifier that is being fed by your tv line out (or earphone output)

Just got two AR 312 HO speakers from my brother. I have a Yamaha HTR 6250. The speakers have (2) sets of cable hook up. One I assume is for built in sub woofers? Do I hook one normal and one to the sub...

do not use those speakers with that amp, those are 4 ohm speakers, which could damage your 8 ohm yamaha amp. you will have to get a 4 ohm capable amp to run the highs, and another 4 ohm amp to run the subs.

car amplifiers are currently 4 ohm, or even 2/1 ohm stable, but few, if any modern receivers can run at anything lower than 8 ohms without a danger of overheating. you may have to get a vintage amp(s), like a 1970's marantz receiver, or a 1980's to early 1990's kenwood power amp, because 4 ohm home amps are pretty scarce nowadays.

whatever amp(s)( you get, verify that they are DEFINITELY 4 ohm stable.

I have an old integrated amplifier and an old BSR EQ-3000 stereo frequency equalizer. i just bought a used bose 901 speaker set. how do i hook-up the bose 901 equalizer in this system?

Hook the signal source to the equalizer input and the equalizer output signal to one of the signal inputs on your amp. This is one way, but this way only one signal source will go through the equalizer (unless it has several signal inputs and a source selector switch).

The other way (inserting the equalizer between the preamp and the main amp) is:

If your amp has RCA connectors on the back named "preamp out" (or similar) and "power amp in" (or similar) that have slugs connecting them, remove the slugs, hook the "preamp out" signals from the amplifier unit to the signal inputs on the equalizer and outputs from the equalizer to the "power amp in" inputs on the amplifier.

Basically, what you do is that you insert the equalizer between the preamplifier section and the power amp section of the integrated amplifier so that you can still select the signal source without having to switch any signal cables (however, i can't say if your amp has got this type of "slug" connection feature between the preamp and the power amp on the rear panel, so i'm not sure which way you'll have to hook it up).

Hope you can make it work the way you want.

No base

Problems like this are usually the result of one of two conditions, the lack of a properly grounded phono cable connection at either the amplifier or the sub. To help isolate this problem, try plugging the end that goes to the amp into a jack such as the Tape Out. If the hum goes away then there is a problem with the sub out. If the humming doesn't change then it is either the cable or the Sub itself.
The other condition is what is known as a difference in ground potential between the amp and the sub. If both components have grounded (3-pin) plugs you may have to isolate the ground of the sub by using a 2 to 3 prong adapter and ground the sub to your receiver.

Cerwin vega ht-10d subwoofer won't work in yamaha reciever

Well, as I know, your Cerwin Vega subwoofer is designed for use with stereo systems. Therefore, it has only 2 channels for input, and 2 channels for output as well. However, you can try this out; the first thing I suggest is that you hook up your main front channels through the subwoofer. All you have to do is to connect the subwoofer input to the front channel output on the amp, then hook up your front speakers to the satellite output on the subwoofer. As long as you make sure that system is working on 8 ohms, I believe this can activate the subwoofer.

Amp wont turn on

Sounds like a fuse issue in the power from the amp - the remote circuit could be and probably is completely independent. haven't been able to find confirmation on this, but if you are confident to take the cover off then check (probably)around the area where the power terminals are there may be some fuses. Hope this helps, ask again if not :)
