Hello, I am somewhat new to the sim racing scene even though I have played F1 games on the PS4 since F1 CE. In the future I plan on having a pc built and get into it a little deeper. I have a problem that I can't figure out and am asking for any help with the matter. Please forgive me because I am not the best with this stuff. I used a single buttkicker gamer 2 on my 1st sim rig and that worked great, but I am wanting some more immersion when racing. My plan is to have 4 aura pro bass shakers hooked up to my 2nd sim rig (currently being built) along with my 5.1 surround sound (Logitech Z506). I would like to have 2 under my seat and 2 by my pedal area and have them hooked up for left and right bias. I am running into an issue with hooking this all up properly. I believe the issue is that I don't have a sub out connection from the subwoofer, it only has inputs. Do I need to invest in a better or different surround sound system or am I able to buy a few extra pieces to get this to work properly? This is the equipment I am using and how I have everything hooked up at the moment . -PS4 -AGPtek audio extractor converter -Logitech Z 506 surround sound -Sure Electronics AA-AB33182 4x100W at 4 Ohm Class D Digital Audio Amplifier Board STA508 (TK2050) -Mean Well MW NES-350-24 24 VDC 14.6A 350W Regulated Switching Power Supply -AuraSound AST-2B-4 Pro Bass Shaker x4 -RCA Y Cable (1 female to 2 male) x4- -HDMI cable from PS4 to audio converter input -HDMI from audio converter output to TV -RCA cables from audio converter output hooked up to two Y splitters (1 for red and 1 for white) -1st Y splitter wire plugged into input on subwoofer, 2nd wire plugged into another Y splitter -2nd set of Y splitters plugged into each channel on amp board (all 4 channels being used) -Each base shaker hooked up to individual channel on amp board I tried this out yesterday and everything worked, but I was getting some sound coming from the bass shakers. What can I do to remedy this? Do I need a different amplifier? If their is any confusion, I can draw the wiring out and post a pic. Any help is greatly appreciated. Thank you.
