I am a new guy just purchase my new car recently!! I planed to upgrade my sound system soon!!
Headunit: Alpine IVE-502E
Front/back: Boston Pro60SE or JBL GTi speakers
Subwoofer: JBL Gti 15" MKII
Amp: Roaster 66 x 1
The question was is the single amp able to support the system? which speaker whould you using for the system?
Pls help....

the roadster should run all that just fine... the JBL is a dual 6-ohm sub, so if you run the sub in parallel you'll get a 3-ohm load and should get 500+ to it. Some will say thats not enough... though at one point I ran an Orion XTR DVC with an MS275 and it POUNDED so I think you will be fine, JBL makes a great sub.
If you are looking for input on stuff to get, thats a whole different can of worms... There are lots of questions to ask/answer like:
Budget?
Listening Style
Music?
My budget build recommendation is:
no rear fill - confuses the sound stage and can muddy the sound
RSDc Comp set (80.00 - 100.00)
Roadster66 (ebay for 450.00 shipped)
RSDc 12 - dual 4-ohm - (125 - 150.00 or so)
just bridge the Roadster 4-channel down to 2-channel and run your components off that and have plenty of headroom
If your budget is higher, the options open up rapidly.
