Getting Full Power?

[adio25 10+ year member]

Since I have one of the screwed up Pioneer decks (deh-p4000UB) where I have to ground the RCAs to the deck ground, I'm not sure I'm getting full power. At first when I installed the deck I didn't need to ground the RCA's but I needed to reseat the deck but when I turned it on it sounded like my sub was getting very little power and unplugging one of the RCA's and grounding it would make it play loud. So I'm wondering if my amp is seeing the full signal from my RCA's because I remember it playing louder before I had to ground but not really sure. My AC voltage on my amp reads 32v on a test tone right around where it should be to stay out of clipping. So is there any definent way I can know I'm getting full power cause my buddies 300w mtx sealed sounds louder than my 500w ported type-r 12" so idk halpp //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
