i think ard $30-40 can liaoz. but u will need the AV output
cable if u hv a power amp.
actually, to set up ur ICE (in car entertainment) properly, it is
not just an amp. but if u r gg for basic, then look for a HU (head
unit) with built in pre-amp. brands like Alpine & Sony will
have it, Blaupunkt & Panasonic most unlikely.
a 2nd hand unit may cost no more then $200, which is just abt the
same as installing a 2nd hand amp but tat amp will not complete ur
system. not even entry level. cos u will need component speakers n
tweeter n crossover filter as well. and these will set u back by
another $300.
think carefully.
