need some stereo advice (LONG)

[White 6s]

here's my system so far. going into my mazda 6..once i figgure out how i'm gonna bypass the stock intergrated stereo and where i'm gonna have the head unit put...here is what i have so far:

alpine cda 7894 head unit
alpine cha s634 mp3 6 disc changer
phoenix gold zx 450 amp
boston pro 6.5 component set
2 jl 12w6's dual voice coil 6 ohm first gen subs will be in a sealed enclosure

what are my best options so far?
get some rear speakers and use the phoenix amp for all four interior speakers. and buy another sub amp?
run the component set and the two subs off the same amp?

is this amp gonna put out enough to run the bostons and subs? here's the specs:


ZX450 SPECIFICATIONS:

Output Power:

4 ohm stereo @ 12/13.8 VDC
18/75 WRMS x 4

2 ohm stereo @ 13.8 VDC
150 WRMS x 4

4 ohm bridged @ 13.8 VDC
250 WRMS x 2

Crossover Frequencies
30Hz to 600Hz

Crossover Slopes
24dB per Octave


thanks in advance

Thats not realy enough power to run the subs in any configuration. W6s suck fo rthe simple reason of there odball impedance. I would use a JL 500/1 to power them. There dual 6 ohm coils mean you have to wire for a 6 ohm load or a 1.5 ohm load if they are on the same channel or 3 ohms or 12 ohms each if they are on seperate channels. The JL is currently the only amp I feel safe reccommending that can do that can handle a 1.5 ohm load. The best you can do off the ZX is about 100 watts a sub, a little shy of the recommended 300 apiece.

What did you use on the before?
I love that phoenix amp!

yeah i didn't think it would be enough on that one amp. i was looking at a 1 ohm stable soundstream or xtant and picking up a 3rd w6. how much u want for your xtant mono amp?

The Xtant X1001 can not go lower then a 2 ohm load.
But since you asked I only want $400 plus S&H.
With the 4th W6 you will be able to run a 4 ohm load and can use any high powered two channel amp and bridge it to get the most power.
