Stereo Thread - questions, queries, bragging,

there are plenty of mechless units out there... dont be thinking they will be the next big thing though like cd was, they are just another option which i can tell you from sales is not that popular. they are very handy for people with off road vehicles or limited space for installation as they arent as deep but at the end of the day if anyone is serious about quality sound cd is the only way to go as it has much higher sample rates etc than mp3 ever will. digital radio is the "next big thing" which will become standard on all radios soon enough either through popularity or necessity. as much as it hurts me cause its not where i work lol look at that jb link above, there are a lot of mech-free, mechless etc units on there for very cheap which have USB AUX and radio and would be great if thats what you are after.

as for the bridging amps questions... it basically lets you load the amp down further to draw more current, more current with same voltage equals more power (watts) and whilst this is a good thing for a sub, it is not very efficient or safe as you can generally only load a 2ch amp down to a 4ohm load overall which takes each channel down to 2ohm each.

to give you an example...
2ch amp advertising 2 x 75 wrms @ 4ohm
will give approx 2 x 90 wrms @ 2ohm
when bridged it will make each channel see 2ohm so combine their power 180 wrms which will be provided at 4ohm
so if you put say a pioneer champion series sub (nice middle range common popular sub) which has an advertised power of 400 wrms in a dual 4ohm setup you would have to wire it to 8ohm which wont get much power from the amp, maybe about 100 wrms at a guess.
if you wire it to 2ohm you will cook your breakfast on the amp as it will be 1ohm per channel which they are not capable of and will either fry or blow the fuse.

you will soon learn what cooking eggs on an amp is like if you do this and try to drive the sub/s as hard as your mates that can be heard from a while away or who enter db comps and talk about how many db they have. a 2 or 4 ch amp is not the ideal way to power a sub for this reason and will only ever give you a small amount of power as their power supplies are not efficient enough for low frequency signal output, the lower the frequency the more power required to reach any usable volume. 2/4 ch amps are designed to run speakers which are much higher frequency and dont require as much power, mono amps are more efficient for subs as they are made to produce low frequency signal so that is why from any "real" mono amp you will see good figures of atleast 500wrms at 4ohm and most will be 2 ohm stable with atleast 800wrms but the better end of the scale will have 1 ohm stable with atleast 1200wrms which lets you have more wiring options and sub combination options.

for how cheap a simple mono amp is these days its not worth using a 2ch if you can avoid it.

sorry if i have been a little confusing, i am not good at putting my thoughts into words for others to read lol

why do people overlook going to autobarn lol its not like we are any different on price for the same units... if we are we will more often than not price match anyway lol

i mean going to repco before autobarn is just crazy, and for that matter so is supercheap, you would be lucky to find someone at either store who knows anything about audio. jb or autobarn these days are the only stores of this level that employ staff who know what they are talking about or have any passion for the industry, SCA employ maccas rejects and repco are a spare parts retailer dealing mostly with trade.

/end rant
 
Just a heads up, SCA don't sell Alpine lol I went to get an adapter for my head unit but ohhhhh no they don't do them -.- haha

Alpine is only available through select retailers. As it is only a few Autobarn, few other specialist retailers have full access to alpine and their range. Jb only have access to a few product ranges of alpine much like they do with kicker. So it depends on what product you are looking for from either brand as to which store you go to. For what it's worth even though alpine is not available at all Autobarn stores all of them do stock the adaptor cables to connect to your car, just not alpine branded cables such as their ipod and microphones etc

Cause Autobarn are too far to get to.
Open a store in my local area, I'd have another option.

I used to go to the Penrith store, but they closed it.
Mt Druitt is my closest now that I know of, but is it worth being mugged, killed or mamed going to Mounty County.
But location is key, why drive 40mins to Penrith of Mt Druitt when Windsor is my local.
 
yeah they've only got supercheap in mcGraths Hill which is the closest to me. I'm pretty sure repco is around there someone too, can't remember but they aren't anywhere near as good as SCA, and as far as I'm concerned, i don't even know where my nearest autobarn or jaycar is haha.
 
Repco is near Bunnings at McGraths Hill, next to Harvey Norman.
There are Jaycar stores at Penrith, Castle Hill & Blacktown which are our closest.
Although I don't really go out of the area unless I have to or have more than one reason and make a day of it.
 
Bragging post :)

Head unit: JVC KD R926BT

Amplifiers:
Mono block - Jl audio slash 500/1v2 ( 500 watts rms 2ohms - 8 ohms).
Speakers - Jl audio slash 300/2v2 (150watts rms x2 - 2ohms - 8 ohms, running front speakers only).

Front speakers: Rockford fosgate punch components (to be upgraded to morel hybrid 6.5 component speakers within the next week). These are secured to custom baffles that have Been sealed to the door frame so no air leaks, Also these are running passive.

Subwoofer: image dynamics IDQ DVC 12 inch (unsure of wattage, I think 350rms at 4 ohms and 500rms at 2ohms) in 1.25cf sealed box.

Boot: custom false floor / amp rack made with access to spare tire well remaining :)

Sound deadening: both front doors deaden & sealed, boot and and rear or car also sound deaden,

Cables:
- power: Stinger HPM 0 gauge to distro which splits into two Stinger HPM 4gauge to each amp.

Grounds: Stinger HPM 4 gauge from each amp to one single grounding point.

RCA cables: x3 pairs stinger pro series ( front, rear, sub), the rear pair is not in use as there purpose is mainly as a spare set.

Speaker wire: cadence 12awg.


Future mods include: new morel hybrid 6.5 components for front with custom tweeter pods built into A pillars, sound deadening of roof and front foot wells when the motivation returns. replace the image dynamics sub with its bigger brother the " Image dynamics IDMAX" with a new encloser to suit, and eventually a third amplifier and a new head unit which will give me the capabilities to run 2/3 way active if need be.

Also all work has and will be done by me :)
 
Bragging post.

Amplified speaker are all on a class d 4ch p that I can't for the life of remember the name of right now.

Pb db of 130.8 about as many db as my car made in kw at the front wheels
 
Well I went to the local stores this morning, looks like they got inundated quickly, nothing was turned on in either store.
Couldn't push buttons or see colours, no staff around as to be expected in the Boxing Day madness.
Might try and get over to JB's on the weekend perhaps.
 
Ahh new repco I was around there somewhere haha.

I'm deciding whether I should install my 6x9's today and figure out how to make my own spacers lol.. But we're moving house soon as I need to pack. Decisions, decisions... lol.

What is better in your doors, component speakers with splits or a 3-way 6.5" speaker?

I know the 3-ways are much easier to install, especially if you have wiring in place.

From what I know, you want the highest pitched sound coming from the front. So for the front id personally go 2 way splits (component speakers/the ones with tweeters seperate) so some 2 way component speakers would be best for the front.

Now just a question.. do you understand the whole four/three/two way thing? Or not?


And Brittany, to be honest im not the biggest fan of posting aha but only like $60 or so
 
Slee, I'm getting a sub soon and according to my step sister (the one who's getting it) she said the brand is the best in Australia, which is bull because I've never even heard of them.. The brand is RE Audio ? Anyone heard of them ? Anyway I wanted to get an Alpine sub coz all my speakers are Alpine now and so is my head unit (yet to be installed) so I wanted them all the same haha.

I think my front speakers are three way and they have built in tweeters :) but recent thing happened when I turn up my music too loud the bass sounds really.. Crappy lol but that may be coz I haven't installed my 6x9's yet lol.

Is there a template or way to make your own spacers for the parcel shelf ?
