Default newbie help about filters

Hi all,

I'd like to add high pass filters (@ 150Hz) to each of my stock 6 1/2" car speakers (4 ohms).

I know there are bass blocker/stoppers things that one can add inline with the positive terminal of the speakers. Are these JUST capacitors?

I've searched this forum and the internet and have found little info regarding the type of cap to use.

Can I just buy caps instead of these bass blockers and attach them in series?? If so, what kind of cap (polycarbonate, tantulum, ceramic, etc), what size for 150Hz cutoff, and what voltage rating for a 30W RMS per channel receiver??

Thanks in advance.

Oh, where can I get these caps in the US?
