but remember all those rockfords can take is 300rms... so if you get the bp600.1 (which is a mono amp and is f'n great) keep the gain LOW so you dont blow the subs...

by the way... Y did you get those Rockfords? and how much did you pay ?

I got the subs at a best buy and they were oringinally priced at 79.99 and I bargained with the sales guy and kept saying I didn't have much money and got him to sell the for 69.99 each.

see he only has 2 subs the 300 .1 is good for him what you think rapture. you know it will knock hard with that amp. posted_image

also the subs he has will drop out at about 200 watts a peice they cannot move any more air he says he dont have money for more subs he should get the 300.1 the 600.1 is too big wasted power bro.

of course the 300.1 will be perfect for those 2 RF's

no fear of lost power or watts nor will the map blowup like the Legacy you WERE going to get posted_image
