Thinking of getting a budget amp and subwoofer for pioneer speakers
 

Hello,

I have the following sound system:
1. Joying head unit.
2. Front speakers pioneer a1686r 350w.
3. Rear speakers a6996r 650w.

These pioneers I think ... em I don't know but I'm looking for more crisp and rich sound I wish I bought JBLs or ROCKFORDs but thought new pioneer speakers with 5-way would bring all the sound crisp levels and the best bass but I think they're just like other standard speakers.

So I'm looking for an amp and subwoofer, if these two equipment would improve the overall sound quality.

Any suggestions?
