No exp with the vmax but Vega was known for there efficiency in the lower line drivers. 95+ I ran a set of the 12" Vega series back in the day and they can get loud on a little power.i have that it is loud and my older brother said that they were a pretty good brand back when he was a youngin (now 35). anyone know if it will be ok in an IB set up? im looking for awesome SQ with a lil thump. this is my first time with car audio and not sure how to go about with it. i like the idea that IB saves soo much trunk space.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
