My friend said that he can hook me up with 2 10" subs 400 wats for about $15. That said I think I would need an amp and new deck for my 97 stock audio accord. He said he got a 1200 watt amp off ebay for about 60 but I havent heard of his brand, do brands matter much in quality of amps, subs? how many watts for the deck and amp would i need for those subs and some 6 x 9's?
