Long story short, I need a little help with the setup in my streetglide....local audio shop put a set of arc moto 602 in my fronts....I had to replaced headunit with aquatic last year....I also have the RF 300x2 amp in there as well...It doesn't sound so well and I can't figure out why...we thought it was because the the rf 300x2 was meant for 2 ohm speakers and I now have 4ohm speakers installed...should I replace the amp with the 4 channel version since it is 4ohm stable???

 

Those speakers need at least 150watts rms each. I'd get a Cerwin B52 for them.

 

what's goofy is the fact that there is 0 bass in them....

 

someone wired it incorrectly then. Make sure you're HPF is not flipped on or too high.

 

HPF is that high pass frequency??? should I be on all pass???

 

i'm really contemplating going back to my polk mm651's...they sounded way better than these arc's so far, but why???

 

It's not the speakers.

It's that amp with those speakers.

 

can anybody recommend an amp that would do these speakers some justice...i also have the aquatic av stereo as the head unit that has a built in 288 watt amp already in it...

 

Slye is dead on with the 150 watts for the Moto's. I would take it a step further and purchase the Cerwin Vega B54 and bridge it to the Moto's. Forget about the 288 watts on the aquatic. Once you add an external amp the internal amp from the HU is disabled. The Moto's are superior to the Polks. You just need some power to push those babies. The PBR300X2 doesn't make the cut.

 

so should I do the b52 or the b54 from cerwin vega???
