I was wondering if there's a trick to adding a tweeter to the front speekers in my scab. The cut-out is already there and I was thinking of just wiring one in. My concern is damaging my headunit. The deck is an Alpine and the door speakers will be pioneer 6x8's from my last truck. Im not looking to dump money on components. I have a 10" kicker I will be adding once I get a box to fit, but would like just a bit more highs. Anyone know if this will work? Will the impedance of the tweeter added to the 6x8 be too much for the deck? Also, I have a set of 6 1/2 alpine's I tried adding tonight but they wouldnt fit. I have the adapters for the 6 1/2's already but the speakers dont fit in the recessed hole. Thinking that they are larger but they are spec'd as 6 1/2's. Anyone running 6 1/2's in the doors that they know fit? (speakers dont fit or line up in the adapters either, wondering if there just odd ***** or if I'm just having a "moment" )

 

I've got 6 3/4" Pioneer Premier TS-D720C comps in my front doors, no trimming necessary. Are the holes in the adapters big enough? I did have to push the woofers down in there to get the sides of the depression to expand.

Tweeters are 4 ohms, just like your door speakers. The only way to get more highs would be to run the tweeters and door speakers in parallel (giving the head unit a 2 ohm load and possibly blowing the onboard amp in your head unit) or you can ditch your rear channels and run the tweeters with a passive high pass in line crossover in the front locations off of the rear power. You could use a passive crossover and simulate components, but you'll lose efficiency due to the crossover. Best bet would be to amp the 6x8s with a cheap 2 channel.
