i was planning on getting a w6v2 and a 500/1 for my hatch, but am starting to lean more towards a magnum. however i want a sub that has great sq as well as spl, but don't want something so power hungry it drains my electrical system. i will be running a sub and comp amp and am concerned my electrical system is not strong enough for much power. my question is how low can a magnum run and still sound good and not be underpowered? and is it a better choice than a w6v2?
