I've read a fair few of the topics and see people talking about poor/low pre-amp out on the preium icc, is this true? If so, obviously you need to crank the amp a whole bunch more to get decent noise but loosing quality at the same time. Is there a way around this? I've just joined the xr6t lifestlye (both forums and carwise, just ask sutty...) and looking for some extra bass (amazing its the fiance who wants the bass). I'm not really keen to add a second head deck, would rather just mod/upgrade the original. I see reference to the alpine vechile hub as well but I wasnt sure if that was just extra inputs/outputs or if it will achieve what I'm after in relation to sub/amp. Also, any recommednations on would goes well size wise? Are 2 x 10's a better choice than 2 x 12's???? Or is it worth the investment. Any information would be much appreciated. Thanks
