I am about to get 2 12 diamond audio d3's with a old school kicker zr600 and want to know how i can get my interior speakers clearer without buying components. I know the subs are going to drain out the interior speakers so how can i get it so i can hear the boom and what the artist is saying without it being distorted.

 

bass blockers on the factory speakers or use an aftermarket headunit and use the high pass crossover in it.

 

The low-pass and high-pass have to be "balanced" and a good rule of thumb is 3 times the rms wattage for the subs as the rest of the system, EG: if you have a total of 100W rms 4x25W or 2x50W , [interior speakers] going to the high-pass you should have about 300W rms for the low-pass, [sub/s].

The ZR600 is a 1x600W rms into 4 ohms, so whatever subs you get need to be wired to a 4 ohm load.

Using the 3x as much power rule you should have a total of 200W rms for the "interior speakers", 2x100W or 4x50W and of coarse speakers that will handle the power. 94

 

just get a nice 4 channel with crossovers...
