your amp shouldspecify how many watts @ howmany ohms it will play...wire you subs to as little amount of ohms u can..making sure the amp is stable..and making sure that it doesnt play too much power....ill take a fewminutes and look at all the specs and tellu what way to wire it ..hold on
125 Watts x 2, at 4 ohms <= 1% THD+N 190 times 2 @ 2 ohms • 380 Watts x 1, at 4 ohms BRIDGE <= 1% THD+N • 75 dBA Signal-to-Noise Ratio (Reference: 1 Watt Output)
the rockford subs are 150 rms...sooo match it to the amp..so u want 125 watts times 2 at 4 ohms...so u parallel wire them down to 4 ohms and then ur set
as 4 the other subs..(i would not recomend hookin up all 4 subs) u would have to wire them to 2 ohms in parallel..or just use one at 4 ohms...
but if u are not sure...go to a profesional place and ask them to instal the subs..."making them be as loud as possible without a chance of blowing them..and they will wre everythin perfectly for 60bucks...well worth it
