the best way to get the BEST deal is to buy used amp/subs... make sure they they are in good condition. i just bought an amp and a really nice set of subs for 200$... which i checked and brand new they were like 350+450 $USD .. i saved alot. i made sure they were in good condition, and i kept the sellers info in case they were bad for some reason. but i couldnt have gotten better with 500$ buying brand new... let alone 200
yes 1000 dollars would buy you a very decent set up
you can get good sony jvc or pioneer decks for 1-250
speakers for front ant back will cost about 230
sub 300
amp 300 whats left you could use to pay for installation maybe
what id reccomend
JVC head unit with auxillary in
pioneer speakers
alpine type r 15 inch sub7
alpine amp
