hertz speakers
 

Just picked up a hertz sub i found on ebay brand new. Dieci 30.3 or something.. think its their bottom end gear. Looking to pick up components for front doors next week and will eventually be amping the lot.
Anyone had any hertz speakers? Been looking at some 13cm components, theyre 100 quid from source sound in Sheffield. Never amped any speakers before, theyre 60w rms, and the sub is 250rms..
Will this give me high volume and fill my car? Also.. need to sort amps yet, should i buy something with a slightly higher rating than the speakers need so i dont have to run the amp flat out?

Also, gna buy 2 amps, 1 for speakers and a separate amp for the sub so i can put in more speakers or another sub.. are there any benefits to buying a mono (something) amp for the sub rather than bridging and amp?

Cheers
