Hey everyone I just bought an IS350 used yesterday. Coming off of an 00' GS300 i love it! The sound systems is great, but I'm for want of a little more bass power. My questions is, if all I wanted to do was install one or two 10" or 12" subs in the trunk, what would be the easiest way?

Would it be easier to install a second amp that runs just to the subs? If so, how would I go about that?

Thanks in advance,
