Yup....that's right....i just got myself a Subwoofer in my 1.3 litre Skoda Felicia...and i just gotta tell ya....It's GREAT.

and also for the fun fact that having good car stereo makes you feel good often at times...especially at the wheel...

so now my car stereo consists of:

JVC KDG431 CD/Mp3/WMA Player 4x50w rms MosFet

2x Jbl GTO6527 16,5 cm 2-way speakers (180w//60w rms) 2 ohm..

Some noname 680w amplifier wich btw works great for my huge box wich has 3 10" MTX Woofers ☺.

p.s. It kinda makes all the seats in my car shake like hell.

Cool, did you change the front door speakers?

nah....i didn't bother....it sounds awesome anyhow

Sorry to drag up an old post, but I picked up a cheap sub and amp from an aquaintance and was wondering how to wire it in. (I have a felicia hatchback)

I assume that there are wiring channels in the car for the rear lights etc that I can use? And as for power where do I find an engine-live? (Or should I run the risk of draining the battery by not paying attention?

Thankies muchly!!

You'll need to run a power cable from the battery to the boot because an amp will probably nuke the standard wiring with the current it'll try and draw (if that's what you meant by using the wiring channels in car). Your head unit should have a remote lead which will take care of turning the amp on and off for you. If your head unit doesn't have one then it'll probably be worth upgrading to one just to make life easier.

There is a good earth point that I used for mine on the N/S by the rear light cluster. Just whip the bolt off and stick your wire in there (prefferably with a ring crimp connector thingy!).

I put the power, remote and speaker wires down the passenger side and it really is easy to pull the plastic trim up to stick it underneath.

Also I find one of these handy from halfords:

Vibe Amp/Box Quick Release Plug from Halfords Price £9.99

Allows you to quickly unplug the amb to remove it in case you need to get to the spare or just need the boot space!

Thanks for the help guys!! Its much appreciated. It's all fitted now, but due to some witchcraft it wont work properly with my headunit (when tested with someone else's the amp / sub proved to be fully functional)

I am now wondering if the plugs marked RCA Preout on the back must go into a preamp before the proper amp, or if my headunit is just ruined =(

any advice is greatly appreciated as ever =)

What type of headunit is it? You may need to activate them or turn the sub volume level up if it's a sub-out on a higher spec unit?

Its a pioneer DEH-3900mp I had a play with the settings (pushed all the buttons, some of then twice, even!!) but can't find anything to turn up the sub, which is a bit annoying, and downloading the manual threw up a blank too =(

When I was fiddling about though I noticed that it looks as though the unit has been dropped at some point, so possibly the output is shorting against the body of the unit, unfortunatly I dont have the keys on me at the moment to try to bend it back into shape and see if that makes a difference...

One thing of interest is that some signal does get through but its rediculously low volume =/

Has anyone come across this before? Is there some awesome combination of buttons I must press to get my sub outs firing on all cylinders?

So many questions! =D

thanks for the help also Schern!

Have you tried adjusting the fader? According to the instruction manual the pre-outs are for rear speakers so if you have the fader set all the way to the front it would do what you're describing. Might be worth having a play with that and see if that helps at all.

Even setting the fader all the way to the back the head unit must be maxxed out to achieve any sort of listenable volume, and even then its only as loud as hushed conversation from the sub.

I think its borked =(

Did you try a different head unit in your car or did you move the sub and amp over to someone elses? It's really a fault diagnosing process now. It could be the RCA cables or head unit or all sorts of other things. If you can I'd try a different head unit in your car. If that doesn't solve it then try running another set of RCA cables (just drape them over the seats and have a known good H/U in your hands rather than installed in the dash if cables are long enough) then it'll be checking the power supply/earthing etc. Hopefully you'll get it sorted!

eheheheh....

I actually left the sub/amp/wiring in my car, and connected it to a headunit in another car =D

With that in place the result was a fully functioning sub, hence why I think the headunit is to blame... =(

Time to get on the blower to try and source another headunit for further testing and/or as a replacement, methinks =(

Thanks again for the help =)
