Hi I'm removing the delco factory radio with the cd and cassttte player . im installing a alpine CDE-HD138BT RADIO . want to use the 6 factory speakers . my question is to use the six speakers and the radios internal amps have power only for 4 channels will in need a six channel amp or can I place the four front speakers wired together . im talking the dash speakers and front door panels speakers wired together . I seen that alpine makes a small amp that's rated at 45x4 and its d class amp too .I want to get better sound from the alpine unit being its a upgrade with it having sirus radio and HD radio too .I've owned alpine in the past the green panel light ones from the 1980,s and was always impressed with the sound too .


so what will I have to do without blowing out the radio .I installed them in the past so not a problem and they have the proper wiring diagrams on this website too for my 1998 chevy blazer LT with the premium sound system .


oh one more question can I get a stand alone cassette deck I can use in axillary input on my alpine radio
