Hi there.
I'm a complete noob, so please do bear with me, I really do need help and am willing to listen.
I purchased 2 Visaton 4W 4 ohm speakers a little while ago for a project I'm working on (need small size and full range) and needed an amp. Not knowing much about speakers, I bought a nice little amp from Sure Electronics. It's an 8W amp which is fine, but it's 4ohms. As you know, that means at 50% volume I'm over the rating of my speakers, and they begin to distort past that point, you know the drill.
Basically, I need a fairly simple solution which will give me the right impedance for my speakers and it needs to be in a very compact package. This is the board, I just ripped off those horrible wire clampy things (man I'm tired, can't even remember the name) and soldered the speakers directly to the board.
If there isn't an existing board that's simple like that, what would be the easiest way to build a little amp? It needs to be no bigger than that.
I'd need
- A list of components
- Circuit diagram
Simple really is better here.
Thanks,
Ross

There is some confusion in your satatement... It's an 8W amp which is fine, but it's 4ohms.
If the amp is meant for 8 ohms, connect 4 ohms, 5Watt resistor in series with the speaker
Or all you need is a resistor at the input to reduce the input signal level or control on your hands to not turn the volume beyond an imaginary set point.

This is what I'd planned to do but saw that people said this wasn't a good idea or wouldn't work.
Do you have any suggestions where to get these resistors? When I looked they were very expensive for what they were and it seemed more cost effective to find a suitable amp.

LISTEN to the music/audio coming out of the speakers.
It's YOU the operator that controls the VOLUME/DISTORTION that YOU hear.
There is nothing wrong with using a genuine 8W into 4ohm amplifier feeding a 4W 4 ohms speaker.
It's OPERATORs that blow up speakers.

You can use those speakers fine with the Sure amp. Those amp's power ratings are usually not listed truthfully anyway. What is the amps model number and supply voltage your using?
I have a couple Sure Electronics amps and other Sure products and find them to be of dubious quality.

Ignoring the other ignorant response, yes, the speakers work fine, but the amp pushes too much power to the speakers if I turn up the volume.
The amp is great, but it's just not designed for my speakers. I want to be able to turn the volume up to full in software and not have to worry about distorted audio or blowing up the speakers.
Turning up the digital attenuators to zero gain is quite normal, especially for best performance/quality.
Use an attenuator between your Source/s and the Power Amplifier.
