What sized speakers off standard head unit?
Please excuse my ignorance but I don't know a lot about sound systems.I've changed the front speakers in the VY to 50 watt or something and put around the same wattage speakers in the rear parcel shelf, some second-hand shit brand I got given. They fit the removable sections in the VY parcel shelf. To connect them I disconnected the rear door speakers and tapped the wires. I did all this ages ago, they're all just running off the standard VY blaupunkt headunit which I am going to keep. However when I turn the volume up over about 45 the speakers cut in and out slightly. Is there a limit on the wattage I can put in without an amp and if so what do you reckon would be the max? I may buy some decent 6x9's for the parcel shelf. Thanks.

In short theres no "limit" on wattage speakers that you can run off the head-unit.
If you were to go out and buy 100wrms (something like 300w max i suppose) speakers and mounted them properly, when they start to distort its more than likely not the speakers distorting, its the head-unit thats sending the speaker a distorted signal. So basically what im saying is you wont get the maximum volume out of those speakers when running them off the head-unit.
Probably this is whats happening at the moment with your speakers, but "cut in and out slightly" dosent sound like distortion, it sounds more like theres a speaker wire touching metal or each other a tiny bit, and only becomes a problem when theres a more current passing through. Its hard to diagnose though over the net.

Ok thanks for that Holdenboy, i may look into buying decent 6x9's for the parcel shelf and maybe something better in the front doors too. I'm not after a total "blast your brains out" sound, just good quality and maybe "occasional" excessive volume.
Most headunits put out 50w x 4 at max, so more than likely it is 12-15WRMS x4. So speakers with an RMS rating of up to ~40Watts should be fine.

ok just disabled the auto distortion inhibitor thingy in the calais and now the speakers are show their true (dull) colours. Would replacing all (10 I believe) of the speakers with decent quality ones be the best option or disabling all except 4 or 6 and just replace them? I don't need a great system but these are pretty bad.

Were you serious when you said replace all 10speakers....??

If i was you and just wanted a small increase in sound output/SQ i would just replace the front speakers with decent quality co-axials (around $80-$100) and leave it at that for the time being. If youre still not happy then go for a set of 6x9s in the parcel shelf (disconnect the rear door speakers), I'd imagne a good set would cost $120-$140 or so. Generally i dont suggest 6x9s but in your case they provide better bass output over the stock 6" speakers and dont cost all that much.
You will have to "punch out" the peices of sheet metal in the parcel shelf, and buy some speaker grills to install in place of the peices of cardboard on the parcel shelf, but it will be worth the extra trouble as opposed to just replacing the rear speakers with co-axials, thats ofcourse if upgrading the fronts dosent provide enough improvement.

My first step, if it was me, would be to disconect the 2x factory subs, and add a decent 10inch, or possibly a 12, depending on your listening style. I've heard a few of the Factory Premium Systems, and i find the factory sub's, produce too much mid bass, which muddles the sound, and tends to drown out the higher notes, that would hear with a better set of splits, or coaxials.Originally Posted by VZCalZone

where are the factory subs?

you should have 2 8 inch subs in the rear shelf...do you not? what model Calais are we talking about hear? and all though it say's 10 speakers, it only has 8, 2 of the speakers are two way, which to Holden, added up to 10...

thats probably why i couldn't find the last two. It's an '04 VZ Calais. Do you know what size are in the doors.

6" speakers in the doors.

ok no subs, had a look and only one parcel shelf speaker was plugged in. sorted that. with the so called premium factory systems are there more outputs or the 4 outputs divvied up to however many speakers you have? If so then would disabling unneeded ones ie rear doors enhance the remaining?

Ok today I tried the system to see how much sound would come out of her. When the volume was up around 47 the passenger's side speakers front and rear stopped altogether until I turned the h'unit off and on again. Oh yeah I checked and I have 60 watt three ways in the front and 30 watt cheap pioneer subs in the parcel shelf. It's always the left hand side that cuts out and/or stops.

I'd be checking the wiring at the speakers first.
How did you connect the wiring to the speaker?

whats going on i just realised theres 2 different threads in here..

the thread stayed quiet for a few days so I re-invigorated it. Go back to VYMAD's question. He's back baby.

I don't see why that would cause front AND back to stop working at high volume until the headunit is switched off and on?
Why am i being called baby.....??

The head-unit will have some type of protection built in i'd imagine, hence the reason why you have to turn off/on the unit for it to work again. Alot of aftermarket head-units have this function too.
Maybe its only one speaker thats causing the problem, but the signal is being affected on the one side (the left in your case).

K thanks for your help I'll let ya's know how it goes if/when I stick better speakers in.
