This is my first post on here, so I hope I'm obeying all the group rules, but I did want to share a fix for a problem I've encountered with my subwoofers.
If you have an infinity ps8, ps38, ps10, ps212, ps410 etc, you may get an issue with your amp overheating, (blowing capacitors, e.g.) which i have read a lot about on here. Options to cool it regarding drilling holes in the plastic amp enclosure, yanking the amp board etc, seemed to be what I've seen as alternative fixes. Another was to pull the amp and build a new enclosure for it. Well, I'd like to throw an idea in the ring that worked for both of my PS-10's.
I was reticent to start drilling vents into the amp enclusure, so I thought, why not offest the mount? Heres what I did. I strted by going to a local hardware store. the original 10 main screws are a #6 x 3/4" full thread cabinet screw, and the two smaller ones are a #4 x 1/2". I replaced them with a screw half an inch longer, as shown below.(actually, I cant upload any photos until my third post, sorry) they were silver instead of black, but I'm ok with that. I also bought matching spacers - 1/2" long, by 3/8" wide, with a hole whose ID matched the #6 screw OD.
I then added the spacers between the amp face and the enclosure, as seen in the following pictures. It gives a 1/8" air gap around most of the board, and at the bottom, you can see more air spacing around the power cord. I don't know what the exact torque used on the screw was, but hand tight worked for me. No sound degradation whatsoever, and it hasn't rattled apart with me thumping them out when I'm in the mood for more bass. I hope this helps some people out there. The total cost of the fix was $4.31 with tax.
Oh, and if anyone has a PS-10 they'd like to sell&ship for under $150.... I'd like two more.....
