Re: sorry guys but i can't search for this
unlike ham radios, car audio amps by respected mftrs are UNDER rated, so if you get something like a JBL 1200w amp, it actually produces 1300w RMS and over.

long story short
i've looked at several amps that all advertise 400Wx2 RMS but i just don't trust those values when the amp is only 300-350 bux. am i being paranoid or is amp advertising like every other product. (ex ham radios) when i buy a new ham radio they advertise 200 watts but it really only means 200w peak which is like 130w RMS. i fully understand the RMS/peak theory and am wanting an amp to most efectively push what i've got.
thanks and sorry for the book.
You're looking for a 800w@2ohm mono amp. If it were me, I'd look for maybe a 2 channel 200w amp that can drop to 2ohm mono stable. It'll probably give out at least 600w RMS or maybe slightly more. A monoblock D class amp will draw less current, and at 800 watts, I think I'd take class D. So ask for "a monoblock 800w RMS amp, with a max budget of $$$$."
You can also have a bit more than the power rating of the subs. Rockfords are known to take a bit more than advertised.
I'd like to help you more, but I don't know the prices of stuff in the US. Oh, excpet JBL's cause I was about to order them.
The subs might be alright with 300w RMS each, so maybe a JBL 600.1? It drops to 1ohm mono and it would probably put out more than 600watts, so your subs would get at least 325watts. Price is around $200. JBL monoblocks don't have subsonic filters, but it is arguably the most bang for buck.
