I must be going partially deaf because I can't say the amplifier was worth $500. The amp is extremely power hungry; luckily I have a 250 amp Alternator and two backup batteries so I can supply the demand. Don't ever think about buying this product without a Big Boys electrical system because I can see it shutting down after hitting one note. The amplifier states that output is wired internally so I have 2 subs wired to the same terminals at .5 ohm and I don't know if it's legitimate but it never shuts down or overheats and I pound them all day long. If your system is prepared to accommodate this amplifier then get it, because it is uncontested in every aspect. I have the T1000-1bdcp running to my third center sub and it seems to perform a bit better with more excursion but that's because it must be easier to push one cone instead of two and the amplifier puts out 1521 watts rms when my sub is only rated for 1000 rms.
