Speaker wiring....

[BHarv]

Ok first off I've searched the hell out of this with no luck.

I have a 2006 XS-P with the regular (6-speaker) system. I just installed the Scion PT546-00140 touchscreen head unit from a 2014 FRS and am now looking to upgrade the speakers. I will not be running an amp so I will be powering the speakers from the built-in amp in the Scion unit. So here comes my couple of issues.

First, I have the rear locked down (obviously), just a direct replacement with another set of 6.5 coaxials. I'm thinking something that has a low RMS like these here (below) because the new head unit only puts out around 11W per channel. And yes I know it would sound way better with an amp, I'm just replacing these speakers now because I have the door panels apart because I'm replacing my chrome handles with color keyed.

Rears: Alpine SXE-1725S 6.5" Type-E Coaxial Car Speakers

So the issue is the fronts. What is the best way to go here?

Option #1: Do I replace the front speaker and tweeter with a 6.5 component set? Obviously will need an adapter for the stock 6x9 to the 6.5 speaker and just replace the tweeter (might need an adapter here as well). So my big question there is do I keep the stock crossover and not even use the supplied crossover that comes with the new speakers? Or do I use the supplied crossover and bypass the stock one?

If I replace the stock crossover which wires am I tapping into the for input on the new crossover? Just not sure how to wire that up?

Option #2: Do I replace just the front 6x9 speaker with a new 6x9 coax and simply leave the stock tweeter and crossover in place? Or should I replace the stock tweeter with something and again keep the stock crossover in place.

I'm liking the idea of keeping stock crossover just so I don't screw up wiring these things but I'm open to options. I just want to do it right the first time and make the system sound a bit better. I want to keep the little bit of bass that I have currently with the stock system so I'm thinking about steering clear of the 6.5 component front option. Any help would be appreciated.

I put those Alpine speakers in my rear doors with the stock stereo and they were quieter. Not very good speakers. As for the fronts, I would be sticking with 6x9 so that you can still have some bass. I put 6x8 Polks in the front, and replaced the mid range speakers at the top of the door with 3.5" Infinity Reference 2 ways and I am very happy. The door speakers don't have a crossover, the mid rangers at the top have capacitors on them. If you want to go easy, replace the 6x9s with 2 or 3 way 6x9s and it will sound much better overall.

i replaced my stock speakers with jbl gto series 6.5's in the rear and 6x9's in the front with a kenwood head unit. difference in sound was night and day, the speakers sound great and aren't terribly expensive, powered only by the head unit

Thanks for the responses. I'll try out the JBL GTO series speakers and just put 6x9 3-ways in the front and leave the stock tweeter and go with 6.5's in the back.

What did you all do for adapters? Use the stock speakers and take out the cone or just order some from somewhere?

The rear speakers worked fine in the stock plastic housing with a little creativity. 2 of the screws should line up, and I used double sided foam tape around the lip as a gasket. The fronts I used 1/4" black plexiglass sheets, traced out the stock opening, and made a template for both sides for my 6x8's. Same thing on the 2 sided foam tape as gaskets and it worked fine. 6x9s "should" be fine without any additional retrofitting. Just separate the speaker from the plastic housing and you should be good to go.
