hey, i just got a new 4 door tacoma and i want to put a better system in it. i dont want it to be all that loud, just sound better at listenable volumes. right now there are 4 5x7 stock speakers and the 2 up front have tweeters. there is hardly an inch of space anywhere but under the forward seats, so keep that in mind. i was thinkin of puttin a set of infinity perfect components(100w rms, 400w peak) up front and run them on an audiobahn 100wx2 @ 4ohms and 140wx2 @ 2ohms amp. also, should i put sumthin in the 2 back speakers, or will just the front be fine? i dont know sh*t about this stuff (i dont even know wtf ohms means) so please respond if you have any good ideas.
