    I am planning what I want to do in the audio department, with my new Prius (haven't bought it yet). I know...ripping into a car with 0 miles is shameful...lol.

    There are 4 options:
    1. Leave it stock (non-JBL with BluLogic port-installed)
    2. Change head unit only
    3. Change speakers only
    4. Replace it all

    Here are the parts I am interested in using:

    Alpine CDA-117 head unit
    Alpine KCE-400BT bluetooth adapter
    Alpine KTP-445 add-on amplifier (optional)
    Polk Audio DXI6500 6.5" component set (front)
    Polk Audio DXI650 6.5" coaxial set (rear)

    I would be putting the front Polk tweeters in the stock squawker location. Also, if the doors come apart for speakers, I will go ahead and try out the Peel 'n' Seal inside the door skins.

    I think the speakers I've chosen will work fine with or without the amp...but what does everybody think of all these bits?

    Oh, by the way, hi everyone, I'm new here :humble:

    I have installed before...in nearly every car I've owned...which is why I'm questioning if I need to do it here.

    My budget is, well, as little as possible. But, I already have the head unit, Bluetooth module, steering wheel control box, and conponent set of speakers. I am lacking rear speakers, amplifier, speaker brackets/adapters, dash kit, and sound deadening material.

    What I am looking for is this: USB-iPod, Bluetooth (that's CLEAR), and sound quality. I have a thing for Alpine products, but I've found that Polk speakers > Infinity > Alpine, at least to my ears. I want to go as loud and clear as possibly without running a discrete amp.

    Your speakers do 100W continuous.
    The KTP-445 puts out 45Wx4.
    You loose base going from factory 6"x9" to 6 1/2" door speakers.

    If you must go Alpine, use the PDX-5 Amp, 75Wx4 + 300W, and add a sub in back. You save $$$$ using what you have, it just needs a little help. I use a JL HD900/5, but that's me.

    I think a sub is gonna be out. I like my cargo space a little too much, as well as keeping the weight down. Also I've found myself happy with the bass in my previous car, with a PDX-4.100 and Type-R 6.5" (which only go down to 50Hz, the Polks handle down to 35Hz). Also the Polks have a higher sensitivity rating, which I think means they can be as loud with less power? Or louder with the same power?

    The Toyota salesman was trying to convince me that the stock stereo is awesome and I didn't need to upgrade...not even to the JBL... :flypig:

    Understood. Then of the "current" Alpine 4-channel amps, the one I would recommend for your speakers is the PDX-F4. Metra and Scosche have the only single DIN dash kits I know of. These two companies and PAC Audio have most everything you need for installation.

    No one likes the Prius Base radio, so they settle for the factory JBL @ $1K to $3k. Trust "your" ears and question anything a car sales person says.

    I've seen the PDX-F4, it looks good, especially the plug for power in addition to the speakers.

    Metra has a different p/n for single and for double DIN, whereas Scosche has one kit that will do either. And I've heard it has a finish closer to factory. Either company will be fine for the speaker mounting brackets and adapter harnesses.

    I forgot to mention in the first post that I have the Toyota harness for the radio already, and a Metra ASWC for controls. I don't have the special Toyota harness to go from the car to the ASWC. So I'm like 50% there with parts. I just don't relish the idea of tearing a lot of things apart to run power, ground, input, but mostly speaker wires to the amp. It's gonna be weird enough to have the tweeter in the dash, the woofer in the door, and the crossover God knows where. I'll handle it though :spider:

    What is your opinion on vinyl/foam sound deadening material? I don't want the driveway smell, but I have heard that vinyl/foam (eg Frost King) doesn't stay stuck for long (eg 6 months).

    Well I've been driving mine for about 5 months now, like yourself, mine comes with the standard 6CD HU & 8 speakers.
    My opinion is that if you want better sound, which I'm frankly happy with mine, upgrade the amps & speakers.
    As for the HU, looking at the prices of a decent HU, I would consider an alternative choice of leaving the HU as it is & incorporate a touchpad to play a decent library of soundtracks, flexible viewing for movies & built-in GPS. At the same time, you can have the portability of bring it around to do some websurfing or reading when you're not driving.
    Just my two cents worth!

    The stock non-JBL system is seriously lacking, the JBL is nothing to write home about either.

    You plan to try it without an amp is a good one too. Depending on the SPL you want and the amount of bass, the stock non-JBL might do what you want if you use efficient speakers and prep the doors like I did.

    A few of us on the forum have replaced the speakers on a non-JBL system and gotten remarkable results using lesser (as judged by price) speakers than you are planning on using. Take that as encouragement to buy better speakers if you know what you want.

    Since you can change the head unit and/or the speakers, I would suggest going in this order.

    1. Replace the speakers because the stock speakers are cheap, lightweight and poor quality. When you replace the speakers take particular pains to make a sealed, vibration damped installation in the doors. Here's my step by step version, there are also other write-ups on the site but I think I did the damping and step by step comparison in a useful way for someone deciding what to do. Note that my speaker selection was based on a good price and success by others, ot a real comparison. Odds are you have $elected better speakers.

    I chose to skip the peel & seal and go right to Dynamat Extreme. I got enough to do a good job on all 4 doors with some left over for $120 from Amazon. It was too much work to install properly to risk using peel & seal. http://www.amazon.com/Dynamat-10455-Xtreme-Bulk-Sheets/dp/B00020CB2SThe price is up a bit, the 36 sq feet was $120 when I got it.

    How I did the door speakers
    http://priuschat.com/forums/gen-iii...ics/93817-gen-3-non-jbl-spearker-upgrade.html

    The dash speakers also made a major difference. Here's how I did them, heavily influenced by Spiderman's installation
    http://priuschat.com/forums/gen-iii...275-gen-iii-non-jbl-dash-speaker-upgrade.html

    Then, if the speaker changes don't get you what you want, change the head unit. Don't do it in the reverse order, no matter how good your head unit is, the cheap stock speakers will still sound like cheap stock speakers.

    I did change my head unit, but only because I wanted ahead unit with built in NAV. I got a Rosen Nav with no external amp which sounds somewhat better than the non-JBL but it didn't make as much improvement as the speaker changes and door prep did.

    We used Cache for sound barrier. Was thicker and cheaper than Dynamat. I am hesitant about the "Peel and Stick" from Home Depot. I recommend Quad Shield RCAs from HU to amp, which is under my Passenger seat. High potential for signal interference in this car. Cross overs are under Drivers seat, but there may be room in the forward kick panels. Running speaker wire was easy except rear door pillars. There, 2 unused pin holes each side were drilled in the pillar disconnect block to pass the 16ga twisted, rest you just bypass, jump and run through the boots. The console, pillar, dash, kick and door panels come off pretty easy. Most of this info is in here. Remember the 2 screw on the doors, the screws on the kick panels and the clip you "must rotate" on the A-pillar. Both Metra and Sosche face plate kits for the dash are painted and "do not" match the grain. I used MDF for the speaker mounts. These suggestions apply to Prius II Base radio system. If you go JBL, there are is a whole different set of problems and costs to consider.

    PS Johnsky88 has the JBL.

    I'll consider the amp, even though that's more work than I planned to do. I will do sound deadener and speakers, then gradually move to head unit and possibly amp. I don't have to do it all at once except for common things that need taken apart.

    Thanks, no chance to open it up to have a look, but like I say, it sounds fine.

    I've found 7 32"x18" sheets on eBay for $110. Is that enough? (By comparison your link to Amazon shows 9 sheets of the same size for $135).

    Also, I must admit to being tempted by the Pioneer AppRadio, despite the crappy reviews and the lack of good preouts (it has 2, 2V preouts). I tried it in Best Buy and it was...intriguing. But I don't think the SQ is on par with the Alpine (they didn't have a 117 for me to try).
