I am having trouble connecting a powered subwoofer to a Luxman LV-103 amplifier.

So I just acquired this Luxman LV-103 amplifier and I have a subwoofer otherwise not used.
I connected 2 speakers, which worked fine, but the bass in them were lacking.
I wanted to connect a Sony subwoofer to it but it didn't have either a sub out or a speaker out.
Any ideas how I could connect the subwoofer to the amp?
Thanks in advance!

    Welcome to Club Polk!

    Does the Sony have High level line IN and OUT speaker connections on its backside?

    If so, connect your AMP to the Line LEVEL IN, Right and Left channels. Then connect wires from the Line level OUT speaker connections on the sub to the speakers, LEFT and RIGHT. The Luxman will handle the volume of your speakers and the Sony's volume and Crossover selector will handle those functions for the Sub setup. Balance the sub volume to the speaker volume and your good.

    It only has 1 input, aptly named "input".
    Is there anything I could do?

    Look at the picture above, in my previous post. Is the input like the RCA IN above the speaker connectors? If so it's going to be very difficult to wire a sub like that to anything but a dedicated SUB OUT jack.

    You can buy a new Sony with the connectors I list or a Polk PSW 10 for around $100 or less and that would add a touch of bass to your system by wiring it as suggested above. If you're running vintage amps you really need speaker INS and OUTS.

    So I just acquired this Luxman LV-103 [integrated] amplifier

    Power output: 50 watts per channel.

    What speakers are you driving with the integrated?
