    I ordered a 12" Monprice sub for one of my games a while ago, hooked it up and there was barely any bass output even if with the controls on the sub at max. I thought the amp was defective in it so I contacted Monoprice, they had me send them the old one and they sent me a new one. I hooked it up and same thing. I cranked the volume up on the game and I was able to finally get some decent bass out of it but the backbox speakers were way too loud at this point.

    So, it seems to me that whatever is in the amp that picks up the bass signal isn't sensitive enough. Is there anything that I can add to increase the sensitivity output to the sub so I can get better output from the sub?

    What game, is there a crossover, how did you wire it, what impedance is the speaker ... is there bass In the music ?

    Looking at the specs on that thing, I would send it back in general. 50-150hz for the frequency range is garbage for a 12 inch ported sub. Much better options out there for the same or less money.

    This should give you an idea of how to fix it. I would not recommend this sub.

    I tried it on Rob Zombie- which I hooked up with wires alligator clipped to the cabinet speaker then bought an adapter that goes from a mini headphone jack to RCAs and got the same result, little to no bass. I also tried it on Dialed In and Iron Maiden, all having the same result.

    Yeah this thing really sucks! Vid posted it up a while ago in the link Monk posted and it sounded great so I bought one but this sub is junk and hugely disappointing. I hooked up one of my Polk PSW 10" subs right after and it rocked the house, like they are known to do!

    Thanks for the link, Monk. I read through the thread and it looks like you went through quite a bit to get it figured out. So is this ultimately what you did to get it to work: https://pinside.com/pinball/forum/topic/12-150w-monoprice-sub-79-free-shipping/page/2#post-4767871

    Yes that’s what I did. Strip one RCA connector. You will find an outer copper wire and another shielded copper wire. The outer copper wire connects to one of the speaker wires and the inner shielded wire connects to the other speaker wire. I won’t be able to take a picture of mine until next week. Let me know if a picture will help and I’ll get it to you middle of next week.

    I purchased that Subwoofer about 3 or 4 years ago and it was terrible. I didn't ever try to fix it. Out of the box experience was substantially inferior to the $80 ones occasionally on sale (Polk).

    Eventually just gave it away.

    I think I should be good without a picture but if I end up needing one I will let you know. I'll let you know how it turns out.

    There must be variation in quality and components of these things. The high-level inputs on mine work just fine, and it gives a nice clean loud tone even at half amplification.

    I finally got around to hooking up the sub as the link in post # 4 that Monk provided. Finally, I have good bass out of this sub!!! To anyone doing this I would recommend soldering the stripped wires to your speaker lugs because it is so small that alligator clips aren't going to do a good job holding the wire to the speaker lugs.

    I was intending to use the sub only on my Dialed In only but Fish Tales was sitting right next to DI so I hooked it up also and it works. It's kind of funny to hear bass with Fish Tales
