i have 2 jl audio 10" subs i want to put in my cobra.
it has a jvc head unit and mach 460 sound system.

what amp should i run? what size wires should i run?

dont know much about systems but i want it to sound good and do it right.
i think it will sound pretty good since it already does now and jl subs are good.

 

to recomend an amp we would need to know the actual model numbers of the subs or the voice coil and impedences stats, as well as your budget including wires for the install.

 

ill get the model numbers for you asap. i think they are older subs,they look like plain black 10" jls
id like to spend about $200 for the amp and wires.

 

For wires I suggest these

you can use two complete runs and then sell the last 30ft of wire to make back your money. It is out of stock right now but can be bought other places for $10-15 more

as for your subwoofers model number and imp of the coils would be nice as stated above
