Ok, i am not sure if this is in the right section but it does have to do with Audio...Car audio that is...

Ok, here goes...Last night i ordered online 2 pairs of speaker at 50 watts RMS and 200 Peak from Alpine. I also bought a Rockford Fosgate amp...the amp is rated at 62.5x 4 @4 ohms. That is 12.5 more than what the speaker are rated. BUT this is the dilemma...that 62.5 W per channel is under a 14.4 Volts. I own a Honda Civic 2000 and i believe my car is 12V...but some dude that knows somewhat about this said that no 12V is when it of an it jumps up to 1.5 or 14V when the car is on. My buddy said thats not true that your voltage does jump but not by that much.

So...umm...does any one know anything about this. I spent some nice cash on these bad boys and really don't want to blow them...The reason why i bought that amp was because i thought the Wattage per channel will lower since the voltage decreases.

Thx for any helps given..:)

It's been years (15+) since I worked on cars for a living but it seems to me that most of the charging systems run around 13.5 volts. The make and model of your car should not matter when dealing with a car sound system ... unless of course you are installing it in a pre 60's car with a 6v system.

thx man..thats all i needed...i don't think 12.5 watts more could hurt ...i have heard too much low power will over heat you sppeaker's voice coil and produce failure..aka blown speaker..

It sounds like it will work fine. The 14.4V is what is delivered out of the alternator when the car is on, yes. And you will only get 12V when its off, yes. Theres no problem there thou. The speakers are made for that power setup. The 12.5 (theoretic) extra watts coming from the amp the to speakers isnt enough to blow them as the limit is 200, and the RMS is 50. You more or less hit the power requirements on the nose. Set it up and, as with any system, play lots of different LOUD music to break them in. Be careful to listen for distortion thou, and know what your limits are.

Ya know just lately I've been thinkin' about a car sound system and the thought of gettin' a dual 250w 12" Woofer drivers plus 6 200w 3way's and a few amps then ....




















pluggin' the lot into my new workshop PC and bench power supply. :D

Sure glad I don't live next door to you Wiggo! LOL. I'm using a 300 watt JVC home system as my sub and center (4 overgrown desktops for the rest) and the neigbours don't always appreciate that. If one of my neighbors had a system like you describe I might not be able to hear mine!!

Would prolly sound like an echo chamber ... might be interesting for the cave ambience sounds....

Must be nice to have a shop the size of that one. Looks like I could keep the snow off my car and still have lots of room for the woodworking tools! Of course it would need some insulation...

That would make a great acoustic room with a few mods to it...great for a pianoforte...hmm :thumb:

I like the idea of putting a 18" Cerwin Vega Stroker in a sealed box right in the midddle... sure your gonna need a minimum of 1500W to power it, more like 2250W to get the full effect... but you get the idea...

That garage/shed measures 7m x 30m (approx 23' x 97') and can accommodate 4 LWB F150's in it and that elevated workshop is about 18' deep as well. But I'll be buildin' an insulated room along one side of the garage area though for brewin' and clean workroom areas plus shower and toilet facilities though that shold still leave me enough room the park the stationwagon and large trailer with room left over. :D

Nice sized garage! The heating bill on something that size during the winter here would almost put me in the poor house. Would be nice to have that kind of space to work with though.

No heating (except for the ones that I ready have in the brew kits) which is the reason for buildin' the insulated and lined rooms into it. ;)

looks like i was beaten to this one...

damn.
car audio is something i'm good at.

i love my lil set up....

Cerwin Vega is the choise for MAX spl (sound pressure level) in a car or a house.
And my choise for amplifier is Phoenix Gold.

I have used the vega line series that performs to the extreme but don't cost to mutch. The more expensiver stroker series is just insane, ever been in a car with a hard working 15" stroker element or a 18"... :?:

They make your heart beet simultaneous with the music beats.
Not to good for the health though...:knife:

EXACTLY. I have a friend with a 15" stroker and a 2200 watt (not sure on the wattage) Phoenix Gold. ITs INSANE. She loves it. I think she keeps it for certain sexual pleasures. :eek:

ahhh yes


chicks and 33hz

it works...... if you play it for long enough with out them leaving your car

takes about 45-50 secs for it to start kicking in, with a 15" its usually quicker.


make sure you supply them with ear plugs or something similar......... they have a tendency to pull their fingers out of their ears after about 2mins...

JediAgent
01-29-2003, 02:22 PM
nice... didnt know it was exactly 33hz... i should get that frquency on cd...

Olie
01-29-2003, 05:02 PM
it varies from person to person

i have a sine wave that alternates between 31 and 35 hz over 45secs and just keeps going like that for about 10mins.

it also realy depends on your car as well. Some cars just dont "do it." not sure why. Commodores vl->Vx doesnt appear to have any effect at all.

olie you'd be talking about the resonance of the vehicle, lol

im thinkin of fittin my VL with some better sound equipment, hunting round for ideas/suggetions atm, but when i get the rolling bass happening, i'll let you know what the "sweet-spot" is on the VL ;)

Sweet, a car audio thread... :woot:

In the next couple of weeks I am going to get a new system for my car. Right now it has a crappy Panasonic setup with 8 CD stacker.

Seriously looking at going with an Alpine 60x4 head unit and Boston Acoustics 12" 1000 peak wattage sub woofer, amp and Boustin 50 RMS speakers.

Been assured this will be a gutsy system, will be using Compeitor series products from Boston - what do you people think? They are asking for $2300 AU (about $1200 US) all up, whereas they reckon it would normally cost $2800 AU.

Im not quite sure about current pricing on Boston stuff, but i do know its not cheap, and i do know if your going for a good audio system Boston is the flat out best speaker company in the world. As far as loudest, i believe there are a handful of others that can pump out high Db, low Hz speakers. But for a real all around badass stereo, Boston has been rated higher than Bose in many of the articles ive read, and from many of the car audio nuts ive talked to. Boston would be a great choice, and as much as they arent known for ball-crunching subs, i would tend to think a 1000 Watt sub from them isnt going to be a bad choice for any setup. Try to get Boston Mid's and Hi's aswell, coupled with an Amp they recommend. As far as the Alpine, there are "good for the money" Alpines, and then there are "why the hell would you spend that much on a Head Unit" Alpines. Throw up the link, id like to see which of the Alpines other ppl like (They are all great Units, im just not a fan of the way half of them look)

Although I am half thinking about buying one of these purely for the fact they look better.


CDA-7894RB Bass Engine Plus CD Player/MP3 Player/Receiver

The CDA-7894RB is an ultra high quality CD/Receiver that features Bass Engine technologies for sophisticated sound shaping and powerful MediaXpander that regenerates harmonics lost in compression from digital recordings such as MP3. The 60Watts x 4 amplifier, three RCA pre-outs and MP3 compatibility makes this unit a perfect foundation for a premium extended sound system.

I just spent $850AUD on a new amp (was reduced $400) only to find out it was dead after spending 5hrs installing it cleanly.

not happy

waiting for a phone call saying when my new one is ready to be picked up.

Its a bit of a rarity in AUS, took me a while to find one.

Clarion DPX-1001.2

Hmmmmm.... I've got a 15" 500watt (continuous) Definitive Technology home theater sub in my room here, which feels a lot like when I had 2x 12" Kicker Solobarics with a 400watt Hot Setup (Orion) amp in my Jetta (85 GLI Wolfsburg Edt). I am thinking that I could prolly generate the same effect, and, BONUS... my bed would be within falling distance. :devil:

Oh, the ideas I am having. ;)

As for the car audio thread, I had my Jetta dialed in nice, I traded the 2x 12's out for 1x 12" Fozgate on the same amp, I lost a little "boomy" and gained a lot of "punch" which was the hope. I had 5.25" Fozgate seperates in the rear deck, 4" Orion's in the door and Stillwater (Kicker) tweets in the dash all being driven at 1.5 OHMs by Sony (yes, a sony at 1.5 OHMs believe it or don't) 4 channel 70x4watt amp. It was "somethin to listen to" according to my friends. I used to listen to Fluke "Risotto" and Crystal Method "Vegas" a lot on that system, it was so fun! :)

I have a 93 Dodge Stealth ES now, with a pretty nice setup, but no quite the caliber of the previous one. I have two small amps (MTX Blue Thunder Pro and a Clarion......something) with an 8" self powered Bazooka sub. I got a sweet MP3 player for the head unit though, a Pioneer DEH8400MP, it's very cool looking and sounds amazing. Well, here I go, babbling away at the digital prophet, again. To answer the original question, again, I think you'll be just fine. 14.4 volts is about what most modern car alternators put out, so I think you're good to go!! :)

Has anyone personally owned or used Alpine headunits here or is there any other brands I should look at?

Don't want to spend anymore than $1000 AU ($500 US) for a head unit.

Don't want to spend anymore than 00 AU (0 US) for a head unit.

I've never owned one, but my friend has the Alpine MP3 player and likes it a lot. I think they are too exprensive for what you get, personally. I got my Pioneer for $350 using www.pricegrabber.com to find the lowest cost. I would search for the Alpine head unit you like using that engine. :)
