Hi

I got my car pretty well complete for sound but im thinking on adding another amp for my speakers they are alpines type r speakers with 100 watt RMS and 300 watt peak they are runing off the deck right now but i was thinking on adding an alpine amp that is 600 watts max and 100 watt RMS x4 will this work and sound good or should i go a little lower RMS??

also i have 2 alpine subs in a sealed box with a kenwood amp that is wired with 4 gadge wire can i get a distributor block and just use the 4 gadge and split it to the 2 amps or will i have to run another wire??

and should i get a CAP and/or will i need an alternator upgrade?

any suggestions or things i should do differently let me no thanks for all the help!
