I have been laying wiring in my car for me rear speakers, and while doing so decided to have a nose at the standard ones up front, to my surprise they are blaupunkt ones!-I thought they couldve been a tacke GM standard crap, however one informant told me that these ARE standard what I would like to know is now I have 7x10s in up the rear of the car, what should I go for up front?-I was thinking 2 tweeters, but as my system is budget(like my whole car,trying to show how cheap you can mod a car,dont know if its a good idea yet,not going too bad though...)what would be real value for money? cheers in advance
