I'll be purchasing a Ford Maverick with the worst sounding stock system I've ever heard so I will be upgrading. It has 2 spaces under each side of the truck under the rear seat with room for about a 0.65 cu ft ea. I was thinking about going with a pair of Sundown 8" SD-4's wired down to 1ohm. Are there any other woofers you guys would recommend for a seal box? Also what would you recommend for a amp?
