s2k: Full sound system set up

[F20C]

can someone confirm... this setup is without an amp and a sub.. ? just the splits wired directly to a headunit and dynamat xtreme door kits in the doors and it will sound good ?

I'm thinking of upgrading mine without the hassles of an amp and sub...

Why would you want to? you'll be limited to little bass produced by speakers. You'll never pull decent bass out of any speakers their magnets are quite small and so will the speaker. You need to "move air" to generate bass. If your not looking for much bass then i'd say do it. But if you think your going to want more bass down the track dont bother and do it right the first time with decent splits + amp + sub. OH and dont forget the headunit wont be powering the speakers as much as an amp would and if you like it loud i highly doubt that it will support anywhere near 90Db it will end up distorting way before that.
