[QUOTE="ThxOne, post: 8678048, member: 675210"] Yes, remove the paint to bare metal, clean off the bare metal with 91% rubbing alcohol or suitable cleaner then bolt that baby down tight with self tapping screws. Just make sure it's a flat surface so that it makes the most contact. That listing, I did the same one a long time ago. Make sure they send you two blocks because that sounds like the same eBay listing I got mine from. They sent one then argued with me about it then eventually sent me the second. If it is the same listing and they didn't fix it, make sure you get both because they are usually 1 for that price. I say "bigger" amp so that you have more headroom... more available power on tap. Once you have this, you can push the same power you are pushing now but with far less distortion going to the speakers which means, typically, less chance of blowing them. Keep in mind that if you are using a 1000 watt amp on two subs that handle 400w rms such as those P2 12's do, does not mean you are giving them 1000w or 500 to each sub.
