Your opinion on my new car layout project
 Posted by holdenvn on 05-16-2005 11:31 PM:

Hello, I am planning and saving atm for this new car sound project. This is only a speaker layout (havent thought about AMPS or anything yet but pls add your comment if you wish.) Alright I am planning on putting on: Front Door: Components (5.25" + tweeter) [each door] Back Door: 6.5" [each door] Back Shelf: 2 x 6"x9" (in ported box), 1 x 8" sub in between 6x9's (in ported box) Boot: 2 x 12" Subs. in ported boxes>ports going to back shelf I am planning on fibreglassing the boot, doors and back shelf. I am also going to make ports in my backshelf which go straight into the boot (to the two 12"s). What are your opinions and comments about this. I am also planning on using Rockford Fosgate speakers. Thankyou In Advance

Oh yeah By the way. I am driving a 4 door, sedan (Holden 1990 VN.) And I listen to rap, hip-hop. And am a bass fanatic. And am also planning on AMPing all speakers, and NOT using the head unit amp. Please advise some tips, rules, feedback, comments, recomondation etc. Thanks guys

First off, we call it a trunk in USA (only Europeans call it a boot). I personally stay away from any mids and highs in the back, especially reflecting off the rear window...it just really ruins your soundstage/imaging. You can get away with the rear doors if you have to, but I don't even do that anymore. Otherwise, sounds good. RF subs have always needed rather large boxes, so take a look at reccomended sizes these days and make sure you have room!

Oh and also, can I put 3 way 6.5" or 4 way 6X9"s in the front as components (I do not really know the definition of component speakers). Sorry for my dumbassness towards speakers btw. And also what wattage would you recommend for the in car speakers and sub for one loud ass system. Thankyou in advance Oh and also, are infinity speakers any good. And are they as good or better than Rockford Fosgate's. Thankyou

Well, I'm really not sure what you can fit where in your car, but I'll throw out a couple things.

Go to a high end home audio store with your favorite CD and ask them if you can listen to a good pair of home speakers (really high end) You'll notice that where the listening position is is an equalateral triangle with you and the two speakers as the corners of the triangle. Close your eyes and listen, this is the soundstage you are trying to reproduce in your car! SO with that in mind ideally you want all the sound coming from in front of you (unless you're watching DVD's and have a surround processor). You also want the distance between speakers and ears as equal as possible (this is why a lot of pro setups use kickpanels, it's less dramatic a shift from typical doorpanel locations). Notice that in the high end home audio store, they won't play a bunch of random speakers behind you. If you set up the front stage well, close your eyes and litsen, the rear fill will happen naturally with the accoustics of the room/car. So with that in mind, do as little in the back as possible (except for subs). If you have passangers in the back you might do something in the rear doors, but that's just as a courtesy to the guys sitting in the back, it sounds a little funny from the front. And any speaker that is aimed into a window typically will sound like shit and those locations should be avoided at all costs (if you want decent sound quality).

I'm really angry that Infinity isn't made in the USA anymore, but they still have a nice sounding speaker (to me anyway) RF has gone downhill since they started selling in all the big box stores, but they're still a pretty solid product all around. You should listen to a few options and see what you like the sound of (it's mainly personal preference and taste in music which will decide what sounds good for mids & highs).

As far as power, most component or coaxial systems will handle about 100-150 watts (if you want to run more, you'll need to drop some serious money into your components) In fact the infinity's will get really loud off of under 100 watts. For subs...well that's really personal preference, get the best you can afford. It's easier to turn it down then to try to turn it up till something distorts and you start blowing stuff up.

That makes HEAPS of sense. You're a genius. I am wanting the system VERY loud as most my driving would be with friends out hooning at night around Melbourne with a full car of idiots with music pumping up LOUD. This is a big ask, but you seem to be quite an acoustic genius. Would you be able to make me a speaker layout for my car (e.g. FRONT DOOR: 6.5" component, 5.25" 2 way. BACK DOOR: etc etc.) And if you wish to help I listen to rap, hip hop, RnB. That type of music (usually has alot of bass and mid bass) And by the way I noticed you said bass is a personal thing. I was planning two 12" infinities (the 1400W(peak) with 96db sensitivity) in double or triple band bass deagined boxes. Thanks mate. I appreciate your help and expertice.
