Guys just wanted to update with three things i have done in my car of late!
Firstly changed my rear speakers to Infinity Primus 9603is 6x9 co-axial speakers from the older Pioneer Speakers. Should say these speakers are much better!
Secondly I removed the custom Endcan/Muffler and put back the stock endcan! Planning to put a exhaust tip soon.
The third and final thing is, i have upgraded from a JBL 2 channel amplifier to a 4 channel Boston Pro series amplifier! Should say that the sound has changed totally. It sounds more like a home theatre now!
Shall keep posting in case of more updates!
