No components?No type "R' co/ax,the new ones @100 rms,mid-bass,tweeters?With bass that powerful,you might want at least 70 rms for your front stage,When I first began with bass,I went to a shop,I came home with a single **** MA audio 12" sub in a sealed enclosure with 400 rms on it(the amp was 400 rms also),I was only on deck power.When I turned it up,I could barely hear the vocals.After that,I was back on the hunt,I ended up with all the goodies $ 2,600 later.My honest opinion,cars that one hears that have only loud booming bass without the rest is not as impressive.How do you like the Hifonics line?Are they low distortion?I run the Alpine mrd 1005 with the JL Audio`12w-3-3-4 wired to 2 ohms,Alpine 550-f-4 channel,4 type"R" co/ax (100 rms ) and type "R" components,and Alpine 9847 source unit,JL audio 2 ga.wiring kit.ENJOY!!02 SENTRA out..................
