Wiring problems with sirius satalite radio....?

so i started installing my my sirius sportster 5 today and the antenea went great, i managed to conceal all of the wire except for about 7inches comming from the unit. But then the power cord and the aux cord are way too long and all it suggests is to zip tie them?! it looks like crap. I know about the professional installation kit for about $30 but is it concievable to install that myself? or do i just need to break down and pay the pros to do it?
