wow thread took a weird turn.. u can run speakers from hu but need amp for subs won't need huge one for Jensen subs.. 5 channel maybe best for u if subs are single vc..or u can run mids from hu and get mono 500-700rms amp for subs get 2nd amp later or get 4channel for just mids.. or 2 channel to power front speakers and run rears off hu or do same with a 3 channel amp.. if subs are 4ohm dvc u could get big 4 channel run speaker 2 or 4 on front 2 channels and run subs 2 ohm stereo (or wire each to 8ohm and bridge amp 4ohm to both)
