What ever any body does DO NOT perchase skywalkers amps,Jack there has skrewed me and haven't herd from him in two months to make it right and it was may 2010 when I order was placed and now september and still not resolved!If you would like to know what happend was I orderd a 900 mosfet mobile in black case with variable power and sideband delay and a 900 mosfet base black with variable power sideband delay and a remote for the mobile amp.Here is what he sent me was a stright 4pill white case and a on/off switch and a straight 4 pill base on/off switch sideband delay and No remote even if it was here their no hook ups for it!So needless to say i called him and said instead of shipping it back just send me a 1pill base and 1 pill mobile and I will call it good and It took him 1 month to ponder that and finally he gave in back in the end of june first july and won't return my calls and won't answer EVER.I think I might just be SOL.But ANY suggestions would greatly be helpful!Heck I might Just sell all of the amps that I do have witch are both brand new Never used and get somthing small and NOT assoiated with this company/dead beat buisness!!!!!
