I have a new laptop and I am trying to attach a pair of 125 watt speakers into the audio jack. I got 16 gauge wire, a super high-quality audio connector, which I soldered to the speaker wire. The whole thing is set up now and sounds great, but the 125 watt speakers can’t even go as loud as the internal notebook speakers. I have the system volume turned up to the maximum and there is not a volume control on the speaker units. Any ideas?
Sounds like the speakers aren’t preamped. The signal coming off your computer isn’t enough watts to push the speakers to high volume.
Computer headphone jacks usually push about 10-15 watts: WAAAY less than 125! You are going to need a preamp or a receiver. I’ve got my computer hooked up to my Pioneer receiver (via the headphone jack and a Monster cable that’s headphones on one side and RCA on the other – hooked up to the aux input on the receiver). The receiver is amping the sound so my 250-watt home theater speakers sound amazing!
Any audio amp/receiver with an aux in will work fine,and you can pick them up pretty cheap now.
Good luck!

Most likely your laptop’s audio output can’t drive the power amp enough voltage that is why the audio output is low. Maybe inserting a pre-amp or pre-driver before the power amp would solve your problems.
