How to finish my audio system build

[S2000king 10+ year member]

Hey guys, just bought a Lexus IS300 and i have a variety of parts sitting in my garage for over a year that i can't wait to put in. The parts consist of:

- Pioneer P8400 7inch HU

- 2 Sets of JL Audio ZR650CSI

- 2 JL Audio 10w6v3

- 1 Alpine PDX M-12 (For subs)

Now i am thinking of adding a set of the ZR650s in the front doors and a set on the rear stage of the car (can't install in the rear doors not enough room), not sure how components sound in the rear deck?

Also i am thinking of adding 2 JL ZR800s in the rear deck alongside the ZR components to add more depth in the sound... Is this a good idea? if so what amp (power outtage and channel) should i buy to power all the ZR650s and ZR800s?

Has anyone had any good experiences with processors for a pioneer head unit?

Thanks

I'd do the 8's in the rear deck,just use the other comp set as back ups...

I'd find an amp around 100x4 at least.

so, i should just sell one of my zr650 components since there is no benefit in putting them alongside the zr800s in the rear deck?

You could.can you fit the 8s in the doors?

Unless you mainly want the rear speakers for the extra loudness I would instead focus more on your front speaker installation. If you want speakers in the back for rear passengers I'd sell one set of components and get a lower cost set of good coaxials.

As for processors, you could use anything on the market with your head unit. All you generally need is a 2-channel RCA connection from your front channels and the processor takes care of the rest. Some processors will do ambient rear fill, so that's another thing to consider.

I ran the Pio 8400 DD. It's a great deck, but won't match the SQ of a lot of Single-DIN offerings that are comparatively cheaper. If that's not a concern of yours, I think you'll be more than pleased with the UI and the Advanced App Mode. Once you get the hang of the 8-band GEQ, it's not too hard to get things dialed in. Also, the Sonic Center Control isn't too bad at doing Time Alignment, but it's no substitute for a good active processor. That being said, raw signal through the RCAs was pretty good and I would venture to guess the 4V rating is fairly accurate. Testing with a DD-1 (I know, not the most accurate equipment on the planet), I was able to get to 38/40 on the volume knob and maintain a clean signal at both 50Hz and 1KHz.
