no amp that is 75 is going to be good. it would be a mosfet amp. if anything go get a new explod. yeah i said explod. theyve got the new technology or somthin. there nice, and look good. i mean if your lookin on a budget, i always reccomend doing it in stages. id go headunit first. with out a good head unit, no matter what youve got, will never sound clear without a good start. speakes, get some pioneers. there not too much, and sound pretty decent. if you can, get the components set. subs, ebay is your best friend. just look often. like i said, i got mine for 1/3 of the cost. and box wise, make sure its the right size for the subs. boxes play a very important role. sealed, or ported is another decision too.
