MINUS86

Hi

Looking for some help with this please - on whether I should expand:

I have the following setup:
- Sony headunit (not sure what model but it its only 25w x 4 with ~2v preouts
- Alpine MRV F300
- Alpine SPX 17PRO component set
- Alpine SBR S8 4 subwoofer

I have connected the SPX 17 PRO set to two channels of the F300 amplifier. I have bridged the other two channels of the F300 and connected this to the subwoofer (only 150W RMS). I don't play my music at or near the full volume often. Would you recommend adding a monoblock to the system (maybe Alpine M500) to drive the amplifier? I don't often have anyone in the back seat so have not put another set in there for now. But if I do get a monoblock amplifier to drive the subwoofer I will likely hook up another set of 6.5inch speakers for the back. This is in a small hatchback. Any value in upgrading the headunit? It does what it has to but is pretty dated.



Thanks in advance all!
