Has anybody had any problems with their Sound Ordnance B-8PT? Reviews are all good but mine does not seem to work right. I have it securely mounted under my seat, facing up with the speaker about 4 inches from cushion. The car vibrates but I do not get much bass sound. I have tried all possible settings. I did get a little more sound when I switched the RCA input wires.
I bought this speaker over a year ago for a show car I am building and am just getting to the stereo now so I do not know if it is still under warranty.
i haven't heard of any specific issues with this sub, other than the occasional claim that it kinda sucks.
do you have enough room to use some spacers and make it down-firing? sometimes that makes a world of difference.
Thanks J Ro. Reversing the sub would be a nightmare, because then all of the controls would be upside down and facing the wrong way. I just finished cutting a piece of 3/4 pine and slid it between the seat tracks about 3 or 4 inches above the speaker. I angled it so it is aiming the sound waves towards the front of the car, and it sounds great. The rattling I was getting was apparently the result of the speaker aimed at the plastic bottom of the seat (it is a lightweight racing seat not good for reflecting sound waves).
Thanks again. Now I want to try one of my old amps I have in the garage and use it instead of the head unit for the other 4 speakers. I they are all Polk, but the front are just a 4 x 6 plate that I hope can handle the power (60 watts).
I know that I have to take it out and test it, but I did a really good job installing it so removing it will be a pain. I have built sub enclosures before so am familiar with good and bad sound. From the reviews I read, most people like it, though it is not a disco boom box. But I think something may be wrong with mine.
I don't think the problem is the direction it is facing, because there is plenty of room above it. But I can try what you said. Thanks for the suggestion.

but it may just be you don't like the sub cuz it's not that great a sub.
I am not looking for killer sound-just something decent. My daily driver (HHR) has a good system. But this is my race/show car, and most people don't even have radios in theirs. I originally wanted just something simple, but it morphed into satellite radio (share receiver with other car) and a sub.
You make a great point about sound reflection. I can try by putting a piece of wood under the seat to see if it helps, then doing it right and pulling the sub and reversing it.

Funny you say that. I did try reversing the rca inputs and it helped a lot. I have tried reversing the phase and it didnt make much of a difference. But the system sounded better next to the seat than sitting on it, so I think you diagnosed it correctly. I should have known better. When I was younger, I played the drums. And to muffle the sound, we put pillows inside the bass drum. But I wan't thinking when I did the install. Crutchfield actually says that you can slide the sub under your seat. In retrospect, not the best place.
Can't wait to drive my son to school so I can play with my system!
If your head has highpass settings or the amp does, those Polk 4x6 plates can do pretty good with rated power.

if you're happy, great! but i don't understand why reversing the RCA's would make any difference whatsoever. switching the left and right RCA's does not reverse the phase. the difference should have been invisible, unless that's not what you meant.
I dont understand either, but it seemed to help a little. I also removed the right angle plugs which could have been causing resistance.
Because my name is on the business, I work hard to make sure you get the best possible shopping experience. I look forward to hearing your comments .
