Im buying a amp and a sub for the first time and im wondering how to wire up the the sub into my sound system. Would it be ok to just link it up to the rear speakers or is there a better way to do this like going directly into the connecting block behind my headset bit?

Cheers
 
dead easy to wire up. you don't say if you've purchased an amp wiring kit yet, i'll assume you have because your gonna need one anyway.

1: Find the thick red cable in you wiring kit and find a suitable grommet in your blukhead (engine compartment into vehicle cabin) if you cannot find one it is allowed to drill a hole, but use a grommet to stop any future fire hazards and remove swarf. This will supply your amp with a live from the battery, the fuse should be mounted close to the battery. Do NOT connect to battery yet
2: Remove sill trims or if your feeling professional today, the passenger seat too.
3: Remove head unit and locate the pre-outs or signal out sockets (red and white, marked L & R) and also the blue wire labelled 'ant rem' or something I think on the kenwood loom. Plug the pre-out cables from your kit into the appropriate sockets in the headunit and crimp on or attach the thin blue wire from your kit to the blue wire from the back of your headunit.
4: Route the preoutcable and blue switch on cable (remote) to the boot.
5: Route the live cable to the boot, at least 6 inches away from the preout cables or you get interference from the alternator.
6: Remove some of the boot trim to find a suitable bolt that goes into the body of the car, use a sharp screwdriver or again if your feeling professional use a wire wheel in a drill and remove some of the paint around the removed bolt, connect the ring end of your thick black earth cable (from your kit) to this and the other end to the amplifier. Connect your live up to the +12 or +ve socket on the amp, hook up the remote to the REM or S/O socket and plug your preout connection in. Hook up the battery connection and check the amp powers up without the protection light when you switch the headunit on.

The Kenwood 3037A only has enough outputs for a 2 channel amp, so you will need to use Y- preouts if it is a 4 channel amp.
 
i got my sub/amp and power cap fitted for £40 if u dont feel adventerous :D
ive done it myself before twice...anndd its a bit of a ball ache.
u need to do as above ^^

u cant just run your sub through your rear speakers, your amp has RCA cables which carry the sounds to your sub! remote cable (usually blue & really thin) turns off your amp when u switch off your ignition.
black = earth (simple really) and Red is power!
if u do wire yourself remember put your RCA cables down one side of the car & power and remote cable down the other side, this stops interference.

this is the thing.someone asks is X hard to do?
for some its easy and others a nightmare.
to me wiring in a sub and amp is a fairly by the numbers thing but others its like thumb brain surgery ;)
however most of the time it doesnt hurt to try ;)

From their first post they were asking what they need to do giving the impression that they are willing to give it a go. I feel that this should never be discouraged. Mainly for personal satisfaction, something created by yourself is always better than something fitted by sumbody else. Its a bit like a free Pint tastes better than the one you paid for.

spoken like a true scot :D
 
Yeah basically all of the above.

You can't use the built in amp from the HU because it won't output enough power. Your best bet is to go for an amp and sub package as these also come with wiring kits too.

If you wanna go second hand I would recommend it as I got a whole mutant system for £80 nd all my mates are in awe of it.

As for fitting it, it depends how handy you are? all you really need is a screw driver and some patience.

I fitted mine myself and when I 1st turned it on I felt a great sense of accomplishment and saved about £50 too. Its worth having a go and if you muck it up then you still have the option of having it done for you.

Just follow the guide in the guide sectiona nd come back if you get stuck. I'm not really electric savvy but I managed it in 1/2 an hour and the info on this forum is infinately handy. Give it a go(y)
