    no, don't do that, we'd never have any new threads!

    pioneer coaxials are quite efficient - at least in my experience, i've never looked at the ratings, but they get quite loud off deck power (as compared to sony, panasonic, kenferd, or even polk speakers) and sound decent.

    i'm not saying they're the best sounding thing on the planet - by no means, but for 10 wpc rms, they're friggin loud, and clear enough to keep me happy in the cars i've put em in.

    One thing i don't ever understand is why does it say on www.alpine-usa.com, products>car audio>Head units>MP3 Players>CDE-9843, that my head unit has 45W X 4 High Power Amplifier?

    45 watts is "Peak Power"... so it will be around 22 wrms (rms rating is what really matters!) :p

    i was thinking of these infinity ref speakers or these infinity kappas.. would either pair be pretty nice sounding with an alpine solely powering these? I dont care too much about bass coming from them cause i have two 12's... I just need durable speakers that have nice mids and highs and dont distort when turned up loudly. (if thats not asking for too much!)

    Considering I am indeed a polkie, i thot my alpine would be able to push 45 watts for each speakers... Yea, i deffffff need an amp, but i was planning on getting four new speakers? I was looking at this amp, and needed some advice on whether or not it would be a good amp, and last. Again, I'd like to get a somewhat cheap amp, but it still has to perform and last. :)

    another polkie question, is it equally necessary to get component speakers amped as much as getting plain round speakers amped?

    No, that 45x4 will actually be about 10x4 RMS. I dont care how fancy a head unit is, look at its size. Now take that 45x4 head unit and compare it in size next to a simple 50x2 amp. The amp is going to be twice the size.

    No matter what their marketing scheme, a head unit can only be so big so it will never be able to make much power. Even that 10 watts it will actually make will still be at about 5% THD. Head units make a horrible power source.

    Tripath's class T amplifier is coming out in a 35 x 2 rms model... the whole amp half the size of a credit card and only about twice as thick. i believe panasonic is going to be using them in decks.

    size is relative to class and design.

    as far as that power acoustik - i had been considering that amp myself previously - go for it.

    blaupunkt put out a 300watt rms class t amp that was only 8"x8" I thought that was pretty impressive. I wanna see that credit card sized one.

    below is the first generation chip

    11w x 2 rms @ 4 ohms @ 0.1% thd

    it's like 2 inches by an inch by 1/4 inch... tiny.

    the 30 something is comin out soon.... haven't seen it yet other than rumors and internet articles.

    the first generation is 90% efficient @ rated output... doesn't need a power supply either - you just shove 13 - 14 volts right into it and boom you're set.

    90%?!? Wow!

    I dont know what to think about those. Ive always been for stealthy installs but love well displayed amps. Little bitty amps just dont get it for me.

    Still I can see the value in them in cars where space is at a premium.

    someday we'll see a 99.9% efficient amplifier (discounting power necessary to run internal processing) with specifications that rival the finest class A/B hybrids, and sound just as warm as tube amps -- it'll be a long way from now, but I don't doubt it will happen.

    Actually i could care less about bigger chips in headunits. Far as i am concerned they will always be a **** source for power. The next headunit i own will not have a internal amp built in. Im looking for the best sound quality possible.

    I agree witcha on that but I dont think a head unit having an internal amp will hurt its SQ. The only benefit would be you could get more features for less money since you wouldnt be paying for the internal amp.

    Most Alpines have the option to turn off the internal amp. Mine does and Im pretty sure yours does as well. You should check into it if you havent already.

    After looking around for nearly two weeks, i've decided i'm going to stick with the two pairs of Infinity Reference 6012si powered by the Power Acoustik A600-4HP. Question now is, if i've already got two subwoofers, what kind of amp kit do i need for this amp? Would i need any different amp kit if i hadnt already had subwoofers?

    Something like this would work. Im assuming your head unit has 3 sets of pre-outs, so youll need 3 pairs of RCA's as well.

    Ugh. Ok the Id still say buy the multi amp kit and then start saving up for a head unit with 3 sets of pre-outs. It will make your life a lot easier.
