Omega Electrical and Audio Help / Re: rear wing aerial or roof

« on: 28 October 2008, 20:37:06 »

hi. ive had a overwelming responce & thanks to all. the previous comment about a roof aerial apealed to me the most .. but theres no sunroof in my GLS model and the thought of mucking up the nice headling scared me more than a hole outside.
i did check the radio a couple of times as ive just put in a small amp and rear sub. the radio is a little suspect even now. its not the most sensitive radio ive ever owned.
well today started nice and bright. i made a early start. bit the bullet and went for the hole on the rear wing (drivers side) as the spare wheel is the other side. the aerial fitted as if it was meant to be there .. and well clear of the roof & rear window .. so its now out in the open. i gritted my teeth as i cut the 1st pilot hole ... but once i got the rubber cup down on the bodywork it doesnt really spoil it too much.
the chrome could have a touch of matt black on it & i recon it would finish the look off. ..... being a dark color car.
..... and the verdict. great!

thats more like it. now when i scan it doesnt just go round n round.

quick replies .. thanks guys.

i have seen that stick on window replacement aerial .. but i feel anything within the body perimeter aint gonna work as good as a outside aerial ... thats not to say it wont give adequate reception. waffle waffle .. ill have a think on it for now. i dont think i will interfere with the factory jobby. it does work to a degree. .. get the drill out :exclamation

Omega Electrical and Audio Help / rear wing aerial or roof

« on: 27 October 2008, 19:13:35 »

hi. it may be too late to read the outcome but ive had this dilema for about 4weeks now. the radio in this Omega is rubbish. i believe its built into the rear window ... the vertical sections of the window heater. ive been asking around for a stick on window aerial that will work on the STD FM vhf band. so far no-one can help. other than buying a telephone aerial and adapting it ... the only option is a electric aerial on the rear wing panel.
if theres any options ... anyone ?? else tomorrow i will have to be brave and drill a hole in the paintwork

... why the hell vauxhall didnt fit a roof aerial i dont know. i also dont fancy ripping the headlings as its as new.
... the countdown starts .. :-/

Omega Electrical and Audio Help / Re: door speakers

« on: 02 October 2008, 18:09:30 »

hi. i am sorry but ive not explained it correctly!! i should have said the = rear door = speaker grills. doh !!
  ive been looking around the back rear shelf but theres no holes for spkrs.
Dammmm. theres lots of small 2in holes for breathing i guess. in my old cav i had to block them all up .. and then made up some novel mdf baffles to accomodate 2x10,s. shame the baffles are now surplus. but the Omega shelf at least looks quite flat. again not so in the cav. so maybee i might get hold of one of those nibblers and then i could get my 10,s back in ... oooo yes.
  the fronts sound really quite good ... but the back door spkrs are v quiet. ive just put my old Blaupunkt Daytona radio in today .. and must say it made NO difference from the factory unit ... much to my dissapointment. in fact id say the factory stereo had a more dynamic sound ... better lower bass ... strange.
  thanks for your help .. srry i misslead u.

hi .. dont think ive posted this before .. please remove if i have.
interesting reading. anyone know how the -rear spkr grills- come off ... or will it have to be the panels ? hoping its just the grills. tried pulling the grills today but they seem locked in. the old Cav rear shelf grills were just snapped in .... easy. ive 2x twin cone spkrs that are just waiting to drop in there.
the spkrs look easier to fit than the Cav. i had to make aup a special baffle to fit 2x 10,s on the back shelf. sounded ok. nothing to write home about.
well .. hope someone can give me a clue ... before i force something and break the lugs or something.
thnx russ

ps. oh yeah its a gls omega 2ltr ... bog std version ...

Omega General Help / 99 OH-mega 16v auto timing belt dissasembly

« on: 31 July 2011, 11:01:25 »

hi .. sorry if this has been covered .. please point me to the post if poss. ive searched but got no results.
i need some help as the manual is vague. i normally carry out minor service jobs myself .. but ..
2years ago after (9months after purchase) the water pump seized (clatter) and the bill came to just short of £900 for a
rebuild and new timing belt ! we drove from the garage happy cause we really were relying on the car at the time.
to be honest this motor has been the worst weve ever had. it generally gets light use so it comes as a blow when the engine
keeps konking out. scared to drive it.
well friday .. almost 2years to the day we were going to the local shops ... well we thought we were ... and the belt has given up
again! so its stuck in the road once more. under 10k miles --- what to do? ---- a long think :-/
i had a look today Sunday .. and just couldnt fathom out what to undo to slacken that aux belt. i tried to get the timing belt
cover off but leaving the aux belt on .. and managed to crack the cover at the top. the aux belt has to come off i guess.
ive done this before with our last Cav 16v ecotec engine that had the engine crammed in sidewise and i never had this bother?
ive also done a cam belt change on a 8v cav in about 25mins .. so this oh-mega is a dog.
the handbook says something about the drivebelt arm tensioner indicator? wherever that is? im worried i may undo the wrong thing.
on the 2.5 version it shows a sprung loaded pulley .. so im not sure what im up to. can anyone guide me.
ive had some friends views on the situation .. and we all agree the handbook can be unclear at times.

thanks for any help. russ

a little more detail if anyone is curious & wants to put some big 10,s on the rear shelf WITHOUT modifying the shelf in any way. the 1st pic shows how i added a flat surface to the shelf and ported the speakers into the car. then the main baffle was bolted to this just as in a normal set up.

it may look weired .. but its not really much different than using a ported cabinet.
using 2 speakers .. halves the effective volume of the boot .. and using the small shelf ports thru into the car provides damping/loading on the cone. in practice it produces sub bass notes that u can feel thru the seats. impressive. didnt expect that much.
it is slightly odd but works very well. just make sure the ports and middle baffle are sealed. the 2 MDF baffles are bolted together .. rather than screwed. in the early stages i had screwed them together.
this isnt as good. i used 6mm bolts throughout. :exclamation
i havnt glued them at this stage as its still a prototype. i would either glue them or make a paper gasket to cover the whole of the board ... like u would use on a carb. i wouldnt expect much air leakage between the 2 boards ... but if any it would be between the shelf.

and this is how it looks when the 2nd baffle is fitted. just plain old silicone was used to seal the baffle to the shelf ... and plenty of it.as long as the airways are clear there sholdnt be any worries.
nice and stealthy.

ive put my pics of my back-shelf here with my other pics ..
but if they should be in the ICE dept i will delete them.

<< here u can see the underside of the shelf

1st pic is the speaker baffle cut out. you can see where the triangular holes will be cut out to PORT the speakers. seeing as the boot is massive ... these ports should help to damp the cones a bit .. so in theory it should be ok. :-? with 2 speakers it will 1/2 the boot capacity.
the template was cut using a cereal box !!! then marked out and finely tweaked untill it was the right fit. unfortunately without cutting the shelf or dropping the speakers from the top this is all have to work with. i dont want to shell out £££,s to get it done ... so this is just a cheap alternative. .. but better than the rear door speakers!

im contemplating getting a sheet metal nibbler and doing some mods ... but in the meantime ..

this is the 2 pieces of 18mm MDF sandwiched due to the corregatted shape of the back shelf. the piece in front of the baffle fits the small pre-cut factory holes on the shelf. the edges of the holes were sealed with some silicone just before tightening down so as to get a good seal.

this is how its shaping up with the 2x10,s. this didnt take long to do once the template was made up .. as i was able to use just ONE piece of MDF. the speakers have done well as they,re about 5yrs old and been the last 4.5years in the old Cav.

and this is another angle ... its in the final stages .. the wires look feeble but in fact they are 79 strands! .. ive added 2x tweeters on the rear shelf to LIFT the clarity & it seems to have gone quite well.
its not the best sound ive ever had ... but as i said .. now the main baffle is in i can start tweaking it. the amp is an old SoundLab .. small by todays standards .. 2x75wtts rms. this set up ive bridged the amp as the speakers are 8R!! thats 150wtts into 4R.
the tweeters are 4R so its a bit unbalanced .. but ive wired the subs in parallel .. and the tweeters in series/parallel ... giving a final IMP of about 2.6R. as it stands the treble is about right. a lot has to do with the sens of the speakers. the subs are rated at 90DB/wtt .. so they are a reasonable output .. and rated at 120wtt rms 250wtt max.

the wiring ...

the best sound ive had is from some Longmill bass drivers. PSW-2410 .. but the shop who sold them has stopped so i cant seem to get them anywhere. they were never gonna win any high volume comps but it did have a rich sound .. and were ample loud inside the car. maybee someone knows where i can get hold of some?
........
UPDATE : 15th Oct
and ive just got hold of a couple of JBL,s cheeeeep !
a lower price speaker i know .. but these are 4R at least. i was surprised theres not a great deal of difference .. soundwise .. but now i can have 2 seperate feeds to them ... rather than being mono/bridged.

this shot taken from inside the car with the back seats down ...

been trying to fit my old AMP and 10,s in the back. just fitted the back baffle and weired gasket type thingy that goes between the shelf and the main baffle. to be honest it was much easier than the Cav and the last two cars ive owned ... but the wiring has been a nitemare !!!
i nearly gave up .. but after a cuppa and a quiet sit down i was determined to sort it. i looked everywhere but couldnt find a grommet to feed the main power from the battery to inside the car. eventually i got a 30ins steel rod thru the only grommet i could find .. drivers side where the handbrake cable dissapears thru the bulkhead.
hooray !! .. i taped the wire to the rod but it kept pulling off ... after a lot of attempts i gave up on the masking tape & used sellotape .. ( the Mrs suggestion .. !!! ) how did she know these things

ha

but now im stuck trying to get the bl@%&^ wires to the radio. !!!!

well its too dark and im wacked after doing headstands under the dash for the last 2.5hrs. anyhow its getting there s-l-o-w-l-y ... i could have had it all kickin tonite ...
if its not chuckin it down with rain .. tommorow i,ll have another go.
i just hope its all going to be worth the effort.
by the way .. the MDF baffle went in fairly easy. theres 3 slots on the shelf for some nice 8mm bolts ... so i got a good fixture without messing up the rear shelf. hopefully it will do the trick & be stealthy.
It cant really be done with just one piece of MDF though. i,ll post some pics if its a success.

hi .. 1,495.
we know its far from imaculate .. but on the plus side she drives real nice .. engines quiet & clean. its fair condition inside too. we just got rid of a 95 Cav GLS with a 2ltr Eco (Vectra / Omega) engine ... and although that was in imac cond .. the engine was :question :questionwith 140k. a wolf in sheeps clothing.
so far im convinced the oMega MPG is on par with the Cav too!!! the ride is a lot cumfy-er. we are pleased.
