No worries Bro! That's why we're here. Yes. All the amps I mentioned will fit on top of your radio in the fairing of your 2007 SG with industrial Velcro and or cable ties. On the 13 and down bikes FM radio reception is lost with the majority of the class D amps due to EMI or Electro Magnetic Interference. This interference is part of the DNA of class D amps. Not a whole lot you can do about it. The amps I mentioned will maintain FM reception. The aquatic head unit is a good unit but it has no where near the power to push your hertz speakers.
That 288 watts is at 2 ohms. Your speakers are 4 ohms. You're looking at about 45 watts per speaker if you have 4 speakers. You need 120-150W per speaker for your system to sound decent @ 80 MPH.
The only way to achieve that number is an external amp.

Yes Sir, an Arc 125.2 mini. I decided to try it with the amp I had using with my Alpine head unit and Hertz speakers so I could hear it and I haven't ordered the 4 channel amp, rear speakers and lids yet

The Arc mini 125.2 has excellent SQ. The problem is only 70W @ 4 ohms with Hertz speakers. Bridge the amp down to one channel and you will notice a huge difference. You will have to reset the gains due the rated power bridged is 250W. Make sure your speakers are rated at 100 RMS or better and you'll be okay.
