hey, well I have an 06 s2k and it only came with 2 front speakers with 1 tweeter on each door panel and 2 tweeters on each back head rest..so I have 6 tweeters and only two speakers...sounds nice but I want more speakers. Ive already added alpine type r speakers in the front..iam planning on adding two more behind me..but how do I do it?? Where do I connect the wires too?? ohh and I have an alpine HU.. do I just connect the extra new speakers to my front speakers..or........... since I have a different HU I had to purchase the radio adaptor conector...and I notice when I installed that connector it had two extra wires for Left rear speaker and Right rear speaker...so do I connect my rear speakers to that??? Oh and since iam adding 2 more speakers do I need a amp??? When do I need an amp...all iam looking for is for the car to bump without having to have a box..thanx...hopfully someone can help and sorry if my questions r dumb..gotta learn some how.

 

So let me get this straight here...

You have a new Alpine HU, and new door speakers(the tweeters and the mid range woofer), and now you want to....

leave the 4 roll bar tweeters and add 2 full range speakers behind you also...

 

i pretty much have the same question too when i first got my car.

my solution....

added a infinity 4sc amp. 4 ch amp.

two channels powering a set of infinity perfect componet speakers.

two channels powering a set of infinity speakers in the rear.

thats 6 speakers already.

and left the 4 stock tweeters wired to head unit. so tweaters are powered by head unit.

 

yeah iam sorry...its confusing..ok... I have a new HU and new front speakers..and all the tweeters are the stock ones...I want more of a bump w/o having to put some sort of box in the car..so I figured add 2 more speakers in the back....so just wondering where would I connect those rear speakers too??? will it even make a difference?? thanks
