I was looking at getting a Yellow top at some point, but based on their cost and mine still being relatively new, I hadn't bothered with it yet. I've never seen my voltmeter drop below 14v unless it's a very heavy bass song. I have a 1200 watt amp and a 1.2 farad cap, however I'll be swapping the amp to a newer model and removing the cap from the system as soon as I get new cable to rewire the subs. Should make the system even cleaner.
But as for TPMS, I was looking on eBay and found a set of 4 Z TPMS for $217. Anyone seen a better price so far? I'm getting new wheels put on soon and want 4 OEM sensors so they'll be covered under warranty if for some reason it still won't work so they can't say it's from me using aftermarket sensors.
