I have a question for anyone who can help. I am new to the sub thing, and I am wondering if anyone thinks that by going to 2 10" refurb kicker L5's or L7's in a vented box, would be better or worse then 1 15" kicker refurb L5 or L7 in a vented box???? I have a kicker kx500.2 and it will rms at 500 watts into a 4 ohm load mono, and this would be going to the trunk of a 90 caddy! Any feedback will really be appreciated. Thanks, Jaackdeth
