Hello, I'd like to include my system specifications below for reference.

1) Philips HTS5543 5.1 System Subwoofer 6.5"
2) PS-WF450 Samsung Sound Bar HW-F450 6.5"
3) Wired in Series.
4) Amp capable for handling 2ohm,4ohm and 8ohm.

...So are there any risk free methods to increase the bass output on these two subwoofers? I'm also wondering if changing the wiring from series (8ohm) to parallel (4ohm) will have an advantage to higher volumes at the same level.

Below is a list of things I can think of to make better bass output ,however need advise from AVS forumers.

1) I'm thinking that instead of wiring the amp to the subwoofers one time ,I'm thinking of adding a second wire to fool the amp that there is another subwoofer connected.

First off, subs don't measure output in watts, it's measured in decibels, and there's no direct correlation between the two. The power rating of a sub only says how much power it is supposed to be able to handle before the voice coil burns out.

Output is a mainly a matter of frequency response, sensitivity and driver displacement. Power is part of the equation, but a small one.
Definitive answers would require knowing exactly what your gear consists of.

No it’s not a stupid question, how else are you going to learn? Yes you can read and hang out on forums, but we all have our questions that come up.. they just differ is all. Part of our learning process is experience that comes with asking. Just think of the time you saved by asking, seems fairly smart to me. wink.gif

SUBWOOFERS -> Two Subwoofers
Both subwoofers impedance -> 4ohms
Both subwoofers output -> 240W at 4ohms

WIRING -> Series

Is there anyway that I can increase bass output from my subwoofer? Below is a list of things that I would like to try.

1) Instead of wiring the subwoofer one time (one wire for the positive end and another wire for the negative end) ,could I add another wire so that the amplifier think that there are four subwoofers connected?

2) My setup is currently wired in series. It is possible that if I wire it in parallel ,there will be more power output ,and will have a positive effect on the bass output?


If you have any other suggestions that I could try ,be willing to try it out. If you guys need more specifications ,please input below.

I think you are discussing car audio here. If so, this is the wrong forum. If not then I'm being stupid.

Do you guys think that it is advisable to try the first option on my first post? Seems kind of dangerous. Any opinions? Have anyone tried this kind of setup before? Thanks.

These are active subs (i.e. each with their own amp)? Or one is active and you're using that to power a passive (i.e. using a separate amp) sub? Or both passive subs, and if so, what amp are you using? What brand is the PS-WF450? Exactly how are they connected?

The Philips HTS5543 Subwoofer is Passive ,without an amp built in.
The Samsung PS-WF450 is a Wireless Active Subwoofer ,with an amp built in.
"NOTE" My first post has been updated with more details and specifications.

How are they connected? Firstly, the amp inside the PS-WF450 is connected to the PS-WF450 subwoofer. Secondary, the positive on the Philips go to the positive on the PS-WF450. The negative on the Philips goes to the negative on the PS-WF450. (Changed the wiring from Series to Parallel). Here's a link for the wiring diagrams http://www.the12volt.com/caraudio/woofer_configurationsm.asp.

For the above website, you'd need the following information. Two Subwoofers Single Voice Coil 4Ohms.

I'm not using the RCA cables where you'd just plug in and enjoy. Just to add on, the speaker wires should be 20+ gauge. They are very thin infact.

Hope this information is enough, I'm free to give you more information though.
