Do you have an old amplifier or receiver that is lying in your basement unused? Did you know you can actually put it to great use and enjoy a high sounding audio quality? You will find that out and several others.Before we dive headlong into how to connect a subwoofer to an old amplifier, let us first look at the major difference(s) between an old amplifier and a new one.
Difference Between Old And New Amps
Older amplifiers and receivers were not made to be able to feature a subwoofer output and as such you might need to connect to the subwoofer using other methods.Recent subwoofers (home theater receivers especially), however, usually come with one or more subwoofer output jacks.
How To Connect A Subwoofer To An Old Amplifier The Ultimate Solutions
You don’t have to worry if your amp is old, it is still very possible to use your subwoofer with it. You have to first check the back of your old amp and look out for a preamp output.
If it has a preamp output you should try to run a pair of interconnects to your subwoofer from the amp.
If, however, your amp or receiver has no preamp output you should be able to use the subwoofer like it’s just another speaker by using speaker wire to join it to the amp’s speaker terminals.
When that is done you would need to run a connection from the speakers to the subwoofers’ speaker level terminals. You don’t have to worry about whether it’s going to sound just like the other speakers.
Normally, all subs provide balance to the entire sound. The low notes are fully represented and if your subwoofer is good, you should be able to get all the special sound effects that come from your movies and games too. The response can go as low as 30 Hertz or even lower.
