    I have a non-jbl package 2 prius.

    I'm upgrading the stereo system to the following

    Tweeters: Gonna keep the factory tweeters hooked up

    Speakers: Replacing all four speakers with the Kenwood KFC-1693ps 6.5"

    Subwoofer: Placing a Kenwood KSC-W1200T Tube subwoofer in the cubby hole above the 12v battery.

    Amps: To power the four speakers up front is the Sony XMZR704 4 channel amp. and to power the subwoofer is the Kenwood KAC-1502S amplifier


    My only question would be where would i put both amps? Should i mount them on the back of the seat ? My only problem with this would be the anchors in the way, on top of the battery cover? or should i mount it on the plastic tray that goes above the spare tire?

    Also, do i need a capacitor? The Sony Amp is 80W RMS x4 which will probably only put out about 40-60RMS reguarly, i don't plan on blaring the neighbors out of the house. So that should be anywhere from 160W-240W and then the amp for the sub will produce 150W RMS at max.

    Let me know what you guys think

    Thanks in regards,


    Alex.

    You don't need a capacitor, those are for much more beefy systems. Some would argue they're pointless even then.

    I also have a non-JBL Pkg 2 and set up 2 amps. Check my build threads http://priuschat.com/forums/gen-ii-prius-audio-electronics/69676-boston-sl60s-added-up-front.html and http://priuschat.com/forums/gen-ii-...7-jl-audio-subwoofer-amplifier-installed.html

    Additional photos linked in my signature.

    I went with two amps because I was being cheap and got them both for a lot less than a good single amp that would do the job. Now I'm thinking I'd rather have just one amp under the passenger seat. Lots of choices out there.
    I've just added a Kenwood KDC-X995 head unit, will be updating this forum later on that!

    I ended up placing the amps on the cover that goes over the plastic tray above the spare tire, so when i go to open the cover to get to that tray, it's still usable, so basically my amps are upside down!

    Wasn't sure if i needed the capacitor or not, but both amps draw from it when it's needed i've seen the light go off.

    Will send pictures!

    Neat! Looking forward to the photos, especially interested in how you ran wire.

    You definitely won't need a capacitor, especially with the Prius. I think it was F8L that was running 1000+ watts rms, with no issues.
