Technical Upgrading Sub ?

[barwell1992]

the subs not to bad to be honest better than most good enough to shake the rear view mirror

Yeah it' possible to change it for an aftermarket sub or amp, basically u have to cut of the factory connection and have all the wires showing then fit one of these, this connects to all the speaker outputs and also needs a ground which is there aswell..

Now u have RCA output.
Then while ur there use the 12v wire for the remote cable input on the amp.
Then amp ground cable to errrrmm...seat latch which is bare metal. Then run the power cable through the firewall grommet behind the scuttle panel to the battery

Hope that helped

im guessing this would work if i removed my rear speakers and connect them to that RCA adapter? as im not sure if my t-jet has the wires for the sub as mine didn't come with one as standard. cheers
