Rockford Fosgate PRIME R1S412

I have 4 of these speakers in sealed boxes in a boom box that I built for my daughters softball team along with a 10" sub running off of a 5 channel 1000 watt Crunch Amp. They are very clear and well balanced and will handle the volume even in an open air setting.

These things are awsome they really pound in both a sealed and ported box. I had them in a sealed box but just recently put them in a ported box because rockford said they sound good in a ported box when i asked them. They are definitely worth the money and would recommend them to anyone who doesn't want to spend alot of money on subs.

Decent 150 rms sub, just didnt fill my car with enough of the bass i needed, im sure two would be perfect, but i uprgraded to a orion subwoofer and kicker amp pushing 500 watts rms at 2 ohms...

This sub just works. I think it has great value for performance.

These things wam at 300rms paired I have people that won't get in my car because their scared of a heart attack. I can be heard easily a mile away
