Rockford Fosgate Prime R165-S 6.5” 2-Way Component Speaker System

I've just replaced all 8 factory speakers in my 2004 GMH Monaro/Pontiac GTO/Vauxhall Monaro and these R165S went into the front door (main speakers) and dash top (tweeters), along with extensive acoustic sheeting, and I couldn't be happier. The factory 200w RMS Blaupunkt head unit is now showing its real class, and I've dropped my original plan to change the head unit or add amps to the system. The main speaker fitted with zero modification. I bent the bar that the factory speakers were fitted on to get a better angle on the tweeters, but that's the full extent of mods required. The tweeters can be run from the built in crossover from the main, but I got a better frequency response and more authentic sound using the original tweeter channels. I am getting some unwelcome noise at full volume on tracks with heavy bass, but most of that is coming from less than perfect panel fit on the front doors. I'll fix this when I get a couple of hours spare. FYI - 6.5" Sony Explod 2 ways went into the rear seat side panels & 6.5" Rockford full range 3 ways running from the factory amp replaced the factory "subwoofers" in the rear parcel shelf, which were boxed in very tidily given their minimal height. No subwoofers, no problems. If looking for authentic reference sound the bass volume is adequate and only a few lower end herz are missed. However, if youre a big doof doofer then you would be left wanting.

These speakers are great for factory replacement. If you plan to amplify them, there are better speakers out there but these work great with factory head units. Much louder and punchier than factory. I did get 1 tweeter that didn't work but it was just the wire was not in the spade terminal good from the factory. I stripped some wire and placed/crimped in a new terminal and it was just fine.

The best thing about buying speakers is that the size is just a suggestion. Some are bigger, some are smaller... who knows? In this case, bigger was bad and smaller was good, so finding these "6.5" speakers that are pretty much just a 6" speaker was a big win. Also, for my application I needed only the midrange section since the car has separate 3.5" speakers for the higher range, so the tweeters included in this box are still in the box. Finding a budget-conscious smaller 6.5" midrange speaker was a tall order, but these guys did the trick perfectly. Although I can't comment on the tweeter section, the woofer does quite well driven by a 45w/channel amp - not huge bass, but good response for the size & power. Very satisfied... one of the most satisfactory speaker purchases I've made in a while!

Good factory replacements. Plenty of treble and midrange, not much bass.

These new speakers will likely not produce the same level of sound across all frequencies as your original speakers. Different speakers have different frequency response curves, meaning they emphasize or attenuate certain frequencies differently, resulting in variations in sound quality. This difference in frequency response is a key reason why music sounds different on different speakers. I have a 2006 Chevy Silverado 1500, and these have intense high ends and depressed bass response compared to the original speakers. Quality of the speakers are great though!

Love the speakers

Would recommend for those needing a good upgrade for a reasonable price
