OEM amplifier

[78AGU]

Just a few questions bout the OEM amp

Ive got an 07 GTI that originally came with the rns510 but I had it swapped out for the RCD500 on delivery (I regret it now but the cost was stacking up) but I retained the armrest cd stacker.

So now I'm wondering should I have an amp under the seat? Because I dont and my stereo sounds like poo..

And does anyone have the part number of the factory amp? Or a good plug and play option? I figure it would be a pain in the ass with an aftermarket one with line level outs and 10 channels.


cheers

I have the RNS510 but would be very curious to the answer to "78AGU's" question.

It would seem there is no real simple answer to upgrading the sound system. The Dynaudio amp exists as a separate item but it does not seem you can buy it or its impossible to install.
Installing an after market sub woofer and its needed amp and interfacing it with the existing RNS510 seems to be more complicated than rocket science.

The OEM amp is terrible - there are plenty if options, but you need crossovers as well - as the OEM amp includes the crossovers.

I've got a Focal Solid4 under my passenger seat - it's excellent :)

Try FHRX if you're in Sydney.

adding an after market amp and sub is not that difficult at all.

i just added a 600W RMS mono block and a 12" MBQ sub in my golf (with the RCD510)

all you need is a decent LOC and some time.

so its a 4 channel amp right? does it have line level inputs?

How have you got it wired into the 4 channels? I was wondering about this I take it you have 3 channels paralleled into one for the fronts and 2 each side for the rear, and you have hi and low pass crossovers wired inline? I was just wondering how that would work with 3 speakers paralled wouldnt the impedence be too low? Or you have them in series?

Or did you just wire one channel into a 3 way crossover?

I know jack about stereo stuff sorry for all the questions just interested to know cos I'd definitely prefer to get an aftermarket amp

Jason,

What you have done is exactly what I want to do. I don't want to change the existing in car speaker set up or change the RNS510 just was to add a sub woofer with its required amp.

I have done this before on several cars but as you would know its pretty easy with JAP heads units that have RCA line outs and remote "on' power signals. The RNS510 does not make it easy.

What Line out converter (LOC) did you use ?

Would be great if you could go into some more detail, PM me or if your in Sydney show me what you did and I will buy you lunch.

no need for a free lunch.

i used a PAC "Trunk LOC" it was about $70 from memory.

if has the speaker wire inputs, and an adgustable RCA level out put (up to 8 Volts output !)
it also features a line that has remote turn on capability for the aftermarket amp.

i simply pulled the RCD510 out, and tapped into the rear 4 speaker wires, and ran them to the LOC.
i used the rear ones so i could fade the sub out by fading the sound to the front speakers.

it's amazing what a difference jut adding a sub has made.
it took me a little while to get the level setting just right, but now it's at a point where with most
types of music, you cant hear the sub independently from the rest of the stage.
it just sounds and feels like the whole car has more bass down low.

i got the LOC from the car audio australia online store a few years ago, and only recently got round to fitting it.
i just took my time with it, (took many hrs to do, but i wanted it done right)

the AMP is mounted to the floor under the passenger's seat.

Jason,

Thanks heaps for that. Now I just need to find one. Ryda and straithfield dont have one. Ebay has similar but none with remote out and level adjustment.

try this item on ebay

it's not exactly the same as the one i used, but it's by the same company, and it has the features you want.

Just as I received your message I bought the 4 channel version of the same thing SOEM-4. its was the same price. Thanks heaps for looking that up for me much appreciated.

Chris

[85turbo]

no probs.

i bought the 2 ch version when i did the sub addition.
i only wanted to run the sub amp (which is a mono block) so didn't need the 4ch amp inputs.

the amp i have just sums the input 2ch to run the mono amp.

Jason,

What you have done is really all I want to do as well but the LOC I bought seems to do everything for the same price.

Thanks heaps again for your advice. be a few weeks but will let you know how it all goes.

Theres only 1 problem with using an LOC, it may not affect subs as much so if it's just subs you want then disregard this. Your head unit already has what's called a pre-amp inside it. By using an LOC, all your doing is amplifying an already amplified signal. This can cause distortion. Ideally what you need is low level outputs which gives you an undistorted clean signal which you can then amplify

Just my two cents

I take your point but apparently the RNS510 is either coded for high power into 4ohms speakers for all outputs or low level out for an amp. Nothing in between. The LOC I bought is programmable and seems to be able to handle any arrangement. At this stage only want to add a sub with amp so hopefully it should all work out ok. I will report back to this thread once I have done the deed.

That would be cool if you can do low level out for amp. I'd be interested to see if that bypasses the pre-amp. I can only wait till I take possession of my car. Until then I am driving blind with this.

[shauno]

so its a 4 channel amp right?

yes.

I took the car to FHRX, witchcraft happened, and then my new amp & speakers worked.

I posted pics in a thread here, if you want to see how it's installed...

[ozmale]

that's what the LOC does. it converts the speaker level out, into a low RCA out for an amp.
as no connections are made inside the RCD/RNS the internal amp and pre amp are not touched in anyway.

i agree that if you were going to run a full system (as opposed to just adding a sub) you would be better off with something like
the JL cleansweep or the Audio control LC6I, as these have way better filtering and heaps more adjustments and equalising.
but on the downside, they are heaps more costly.

as i only wanted the sub, and im happy with the quality and volume of the stock speakers, ill live with the PAC LOC method i used.
and i already have permanent hearing damage from too many years with high powered car stereo's.

lesson learned the hard way i guess.....

I have the factory amp but the speakers are goooonnnneeee, and I'm looking for a replacement set. Any ideas and suggestions?

Jason,

Thanks to your advice I install my 300 watt Amp and Sub today with the PAC LOC unit I bought. Took pretty much the best part of a day, but it all works really well, PAC Loc switches the Amp off after about 3-5 minutes after you turn off the Stereo.

A sub is really what the golf "R" is missing. Sounds excellent now.

Thanks again.
