If you have 2 10 w7s you would actually need a 1000/1, unless you were looking to run them a little under powered. If not, atleast the 750/1, its 400 and some online I believe. Another good choice for a better price would be a PDX 1000.1 There are also a few other good amps, you're mainly needing one that'll do 1k rms at 1.5 ohms.
my friend has 2 12w7 and he's using an old school memphis 16-st1000d amp and it sounds really loud and really clean. you can find that amp on ebay for under 200 easy ive seen them go as low as 120. other than that your best choice would have to be the jl 1000/1
i end up buying 2 jl 500/1 just wanted to see how over rated the amp i already have is thanks alot. i also have 2 jl 13w7s powered by a 2500 watt memphis mojo whats your input on that
