Is it difficult to add a pair of tweeters to the two outside speaker grill holes on the top sides of the dash? I have a factory radio with two front door ane two rear door speakers, not the infinity.

I'm not looking for tons of wattage, just a high quality pair to suppliment the doors. I have the treble all the way up all the time. If I have to add a small amplifier, that's fine. But, where would you get the low source out of the factory radio? I don't want an aftermarket radio, I like my MP3 factory one I have.

I added 3-1/2" infinity's..pretty easy, that top cover just snaps off and the screw holes are already there. No need to add an amp, just splice off the front speaker leads at the radio.
Sound fills in the truck nicely.

Then I went nuts...switched all the doors speaks to JL Audio, and a 400 watt amp, then another 400 watt amp to drive a 10" JL Audio sub in a hot box under the center consol. And switched to the factory REC Nav.

I didn't even think of that.

Where did you find two infinity dash speakers? Are they the same, or close enough impedance to work? Do they have capacitors on them already, or did you have to add one to each?

Oh, where did you find a pin-chart to show which wires that come out of the radio are the left and right, front and rear? Wait, I have a service manual on CD. Maybe it does.

Stock stereos arent designed for low impedances..... run an amp!

ajpulley

Well, then how do I incorporate an amp with the stock stereo? And, where might I find stock infinity speakers for the dash, beside the dealer?

That's true; however - tweeters typically draw so little amperage that they work well as piggybacked auxillaries

BKCBUILDER

Even after amping, I still left the tweeters piggybacked and un-amped.

I got the infinity's at Circuit City...about $90 for the pair.

Didn't find Infinitys online at CC, but anything is better than nothing.

How did you get that top piece of the dash closest to the windshield off?

BKCBUILDER

Slide a screw driver under it and it unsnaps. It has clips close to driver and tabs at the windshield......4 or 5 clips if I remembercorrectly...very easy.

ajpulley

Thanks, I'll try it.

They look anything like these Infinity Kappas?

BKCBUILDER

Yep...that's them.

I guess since you spliced in at the radio, there is not already a harness there for us. How hard was it to get at the radio harness in order to splice in?

If you go the route of tapping of the other speaker lines make sure the set you have comes with a set of crossovers to block out the bass. If not you are just running full range tweeters and you will not benfit from the highs you are looking for

ajpulley

And they fit right in- screw hole lined up and everything? That's good. I can't wait to try it.

They do, but I'll add a capacitor to the whole thing so only the upper band gets to it.

Actually, I'm thinking of replacing the rear-door speakers too with the Kappas. The front-door speakers are OK. I don't need a theatre in the cab, just something a little better.
