well i know if you upgrade to a monsoon, you have to buy the head unit, speakers, amp, and the wiring harness...which really is a lot of work... plus I dont think the head unit would fit in our cars.. your best bet is to go to a car stereo shop and pick stuff out.. it would be a lot more cost efficient...but be perpared, its still going to cost you some money. as for the power ant. my guess is that the motor probibly went out..which is common. if your good at that kind of stuff you could probibly order a new ant motor off ebay and install it your self..its pretty easy. hope this helps
