'07 H3; Aftermarket radio installation

[96TL]

Hey guys. I have another question (actually two). Which do you think is the most reliable harness? Soundgate, Peripheral or Pac? Price wise, the Soundgate is the cheapest, and the Pac the most expensive.

Soundgate - $130
Peripheral GMAH24B & Peripheral GMAHCM - $155
Pac OS2 & Pac CM1 - $180

Also, I have the stock Monsoon stereo, but I don?t plan on using it at all. Do I order the Bose adaptor, or non-Bose adaptor?

Thanks!
