  • Touch screen w/ amp or computer to amp?

    Hi all, I finally have the funds to begin my carpc project!

    However, I was wondering what would be more cost effective:

    1) A vga touch screen with an amplifier (and radio) built in, like this one: http://cgi.ebay.com/In-dash-7-TFT-To...3%3A3|294%3A50 (Ebay price $285

    2) a vga touch screen with no amp, and find some kind of low power amp to drive my interior speakers, like this screen: http://cgi.ebay.com/Double-DIN-Lilli...3%3A2|294%3A50 (ebay price $259)

    I am not going based on ebay prices cuz i know they can be found cheaper than what i did with this quick search.

    ALSO...

    which way is BETTER? I am not a total audiophile, anything that sounds good is fine

    only thing that troubles me is the increased wiring job (although I am 100% capable of doing it)

    thanks so much!!

    (also, if anyone knows how to fabricate a lilliput EBY701 into something like the ebay link i posted, please let me know! (and dont worry, im gonna search right now )

    external amp is going to be better quality... and the first one had no amp. its just a motorized touch screen.

      Thanks for pointing that out, the correct link is here: http://cgi.ebay.com/In-dash-7-TFT-To...3%3A3|294%3A50 and i fixed the original post.

      I understand it will be better to have a seperate amp, but will it be THAT MUCH better that it would warrant the (im assuming) higher price and increased labor?

        Yes It Will Be THAT much better.. what type of speakers are you running stock? and how many?

        This is a cheap yet good amp if your running 4-6 2-3way stock speakers not amazing but better than what you will get out of that other system

        for a few bucks more this will more than double the one I just mentioned, this amp is also built better than the other amp

          hmm... dosn't seem too expensive...

          right now yes im running stock speakers, but ultimately i plan to upgrade to something slightly better becuase they really really suck lol. Probly some cheap infinity's or something similar... looks like that amp will have no problem for them.

          also, i have a 4 gauge wire from my engine bay to my sony xplod 1200w already, can i split it down to 3 8 guage and use 1 for the sub, 1 for the amp, and one for the pc?

            id go with this for your speakers.

            at least it'll be powerful enough for components if you are going that route. and jensen's seem to be reliable from what i have heard.

              how long do the wires stretch? the amps on the side of the chart should match your alternators amps
              Look at this chart it will help you
              http://pix.crutchfield.com/kb/Chart.jpg

              and that sub only gives out 330watts lol

                obviously i was listing peak watts, because i didn't remember the RMS and got the sub second hand. the sub does not bump... but have you ever listened to something with NO BASS? it sucks! so i just threw that in there to even out the audio and at least have it listen-able.

                the real question i was asking, was whether or not a 4 guage wire will be able to handle all that current.

                wire stretch isn't an issue, i can always add more after the distribution block.

                EDIT: after reviewing your chart let me rephrase the question. will a 4 gauge wire which can handle X amps according to that chart which weve all seen, how many amps will that 700w sub actually pull if its only powering ****ty tinny little speakers?

                  as for speakers there cheap (45 bucks a pair, shipped) yet look good I'm dropping four of these babies in my friends corolla they should sound amazing if they hold up to there specs (as I imagine they will), will let you know once I install em'

                  but were going with this amp, should make them sound and bump very nicely

                    you really think those things are gonna hold to a 600w peak spec? thats a pretty tall order, especially for a pair of pyramids.

                    whats the RMS wattage on that? i couldn't find the info anywhere.

                          No im counting on somethind around 200 rms as they are 4ways

                          and my crunch amp will run a 4ohm x4 at 200rms so it should work wonderfully
                          the woofers in them should sound fairly good but im hooking him up with a 12"er along with those so It should sound very nice

                            sounds nice, you couldn't find the RMS spec either? 200rms is probably a good guess, but, for example, sony xplod 4way 6x9s rated at 300w peak only do 60w rms

                              you mean this amp

                              its 900 not 700 ampers, it will need a 8g wire at the very least I'd run a 4g personally, but a 8g should be fine
