The pioneer TS-Q131C
these are design to replace the standard speakers.
My firend is selling an Xtant amplifier really cheap - he hasn't put it up on the web yet. It is initially a 3 channel amp but can power the rear speakers at low volume to make it a 5 channel amp!
its the 3300X model.
its a chrome amp and it looks the dogs bollocks!!
£250 + postage or £250 collected
let me know if you are interested, i will send you some pictures if you want
but defo look into the pioner speakers.
