2004RX330

Just check out the Infinity baselink T subwoofer which is too long and cant fit behind the RX 330's real seats. Unless have it install at the end of the trunk area which will give up too much cargo space.

It'd fit just fine in my RX300 if I wanted it. The unit is 40.25" wide. The narrowest point between the RX300's strut towers is 39.5". However, I'd mount it toward the rear of the towers where the space is wider, so that the woofer is flush with the strut tower. It'd fit perfectly.

You should be able to do the same with RX330. Besides, you can't put the woofer unit up against the seatback. You should leave some space anyway. Then your local audio shop should be able to make a custom cabinet for you. Similar to the one Evilxlexso posted.

Where would you buy the speakers?

how much would it be to build a box or "cabinet" for the basslink? btw, does anyone with the system have problems with rattling outside the RX? is dynomat necessary?

also, i have never installed a system, how do i install the RCA cables to the stock RX headunit? thanks
