my friend is finishing up his 59 impala convertible its burgundy color with cream interior

i just cant think of any decent sounding subs and amps to put in there.
something that is not sky high priced either. since the car itsself is pretty **** expensive to restore.

im trying to prevent him from buying junk **** and filling it up with random amps and speakers. he is already starting.

he just bought a phoenix gold ms-2125 from pawn shop without knowing many details about it.

what im looking for is something that will look good in that car. something to match the year and style.

and also can anyone post some online stores that sell the old classic stereo replacements..
