Blocking Capacitors

D.S.Barniskis

Have just installed a pair of EX352, and a pair of EX369 speakers in a Mitsubishi Mirage. Put a 120uf capacitor (with 1.5uf and 0.15uf bypass)in series with each EX352 to limit the low frequencies going to those speakers.
My question is, will the big caps have any impact on the internal crossovers of those speakers? IOW is this the correct way to hook up these homemade bass blockers?

I apologize if this topic has already been covered, just point me in the right direction.

Thanks
