I'm putting together a budget system in a Ford F-150 I have a custom box with .69 cu feet sealed available for 2 10" subs. There is a lot of options I've been narrowing it down so far I'm leaning towards the Sundown Audio SD 10 Dual 4. I am going to be running a Class AB Mono channel amp rated at 1400 Watts RMS into 1 ohm load. There restrictions 6 Inch mounting depth 300 dollar budget looking for Dual 4 ohm subs or single 2 ohm subs (Want as much bass as possible from a 2 10" subwoofer sealed enclosure) Thanks for any help with picking the right pair of tens!
