About the Rockford Fosgate P165-SI

As solid as sound gets

Without a doubt, Rockford Fosgate's P165-SI component speaker system is a powerful alternative to the speakers that came in your car. Using an injection-molded mineral-filled polypropylene cone, the 6-1/2" woofer delivers impressively accurate sound. Rockford Fosgate's signature VAST surround technique also expands the surface area of the cone, giving you better bass response than comparable speakers. But no matter how heavy the bass gets, the separate 1" dome tweeter provides clear, extended highs for a rich full-range sound.

Slots on the outer edge of the speaker basket make for an easier installation.

But no matter how heavy the bass gets, the separate 1" dome tweeter provides clear, extended highs for a rich full-range sound.

Integrated crossover

Rockford Fosgate makes installing this component system simpler by concealing each crossover in the speaker basket. That way, you won't have to find space behind your door panels for extra black boxes, but you'll still enjoy the clean sound that results when you channel your lows, mids, and highs to the optimum speakers.

Give your import some American muscle

Do you own a European car like a VW, Citroen, or Vauxhall? Rockford Fosgate designed these speakers with you in mind. Rather than only providing rigid screw holes that may not always match up to your factory speaker opening, the Flex 2 Fit basket design uses slots on the outer edge of the speaker basket for an easier match.

Installation note: You'll need a pair of our universal backstraps to install the tweeters in the factory locations.

Fantastic speakers to use as an upgrade from factory. They have the built in crossover which I wanted/needed because my car door (17 Ford Focus ST) didn't have any space for an external crossover box. The tweeters are very loud so adjust your stereo EQ accordingly. Only complaint I have is that the mid bass seems to be lacking ever so slightly. But I plan to remedy that by adding a powered subwoofer later.

Pros: Clarity, internal crossover, heavy duty construction, crisp highs

Cons: Slightly too weak mid bass

Outstanding upgrade for factory stereo

Mike R. from Santa Barbara, CA on 7/3/2016

2011 Chevrolet Suburban

Verified customer (What's this?)
Verified employee purchase (What's this?)

I had a factory speaker die on me so I HAD to take the opportunity to upgrade all the speakers. The highs are so clear, I eliminated all of the treble boost I was using in the system. The bass is solid and has more presence than I expected from a 6 1/2" speaker. Even at highway speeds, I hear details in my music that had been previously lost. The installation parts and instructions from Crutchfield made installation so much easier. The first door took me about an hour and a half to do. By the time I was on the last door, it only took about 35 minutes. Bottom line: Wonderful upgrade that I would not hesitate to buy again.

Pros: With component speakers, finding a place to install and secure the crossover in the door is a significant issue. I was drawn to the idea of the integrated crossover. It works perfectly and there was one less part to install. Also, these speakers are very clear and well balanced. They required very little EQ correction in my vehicle.

Cons: The mounting ring for the tweeters is rather difficult to install. That said, once it is on correctly, it is very secure.

A nice upgrade over factory

Jim N from Saukville, WI on 4/11/2016

2006 Chevrolet Tahoe

Verified customer (What's this?)
Verified employee purchase (What's this?)

These are pretty nice! I like the upgrade over my 10 year old factory speakers. There were adequate install parts for me to mount separate tweeters conveniently. The range of options was great. And the sound is so much better! If I wanted the sound I get in my lux sedan, I would add an amp and subwoofer; but these are perfectly fine for this vehicle - at least for now.

Pros: Range of install options and parts; nice sound.

Cons: Had to adapt tweeter connect with my own wire ends. For me really not an issue; but for someone who doesn't keep a set of wire ends in their workshop a run to auto parts store would have been required.

Pros: Easy and I mean very easy to install was unsure about no cross over box but it was easier to install and sounds as good if not better

Cons: The tweeter mounts were not as easy as some but works well

I've never heard that before!

Paxton from Sanger Ca on 3/26/2016

2004 Chevrolet Avalanche

Verified customer (What's this?)
Verified employee purchase (What's this?)

My wife has had her Avalanche since new, 12 years. We replaced the deck with a JVC , the factory separates sounded much better. But failed (buzzing in the mid range) with a torn cone in the front left door. Read tons of reviews and had a max budget of $150. I wanted an easy fit with minor fabrication required. Crutchfield had a lot of choices for her truck, chose Rockford. Partly because of their reputation, and based on personal experience with their subs and amps. When they arrived I was not disappointed! Easy install with woofers needing only 4 screw holes to drill and fit perfectly. Tweeters required a little fabrication, I removed factory tweeters and used their mounting plates. Removed driver assembly (broke it out of the plastic mounting plates) used a hole saw to enlarge hole in mounting bracket and secured new larger tweeters with included hardware. Factory door panel remains unmodified. After a few days use she tells me that she is hearing things in familiar songs, and lyrics way more clearly. She's happy, I'm happy!

Pros: Easy install, nice mounting hardware & a huge improvement over factory separates.

Cons: Requires a small amount of fabrication, but well worth the price and effort. If you're good with your hands this will be easy.

massive improvement over the chevy factory speakers

These are incredible, the sound difference is night and day over the factory speakers. I put these in the front doors in my 05 tahoe, I had to do a lot of custome fiting for the tweeters to make them look like they where factory instaled but deffenitly worth it.

Pros: Amazing sounds and nice looks

Cons: Could be a few more mounting options and hardware with the tweeters

Good Fit Great Sound Upgrade!

Crutchfield customer from Michigan on 10/10/2015

2005 Chevrolet Blazer

Verified customer (What's this?)
Verified employee purchase (What's this?)

Installed these speakers in 05 2 door Blazer. Speakers fit well in the doors. The tweets had to be custom mounted as they do not fit in the factory dash locations. The highs are really bright, and the lows sound great. Hooked to a Kenwood Excelon KDC-X799 deck these are a vast improvement over factory and no need to add an amp.

Pros: Door fitment is good sound is great

Cons: Tweets didn't fit in factory location

Never can go wrong with RFosgate from Wisconsin on 6/1/2015

2002 Saturn L300

Verified customer (What's this?)
Verified employee purchase (What's this?)

I love these speakers, have always had a thing for RF gear, but they have earned it! These speakers may be a bit bright when paired with a RF amp with punch enabled, but nothing that some EQ can't polish up!

Pros: loud and solid, hard to distort

Cons: screws and clips (mounting hardware) are a bit flimsy, easy to strip screws or break clips, recommend hand tighten only! especially since speaker frame is also plastic!

Product Research

Features

Injection-Molded Polypropylene Woofers: The woofer cones are mineral filled, injection-molded polypropylene. This molding process assures a uniform cone thickness for superior linearity and clarity. It is also light weight and rigid for decreased distortion and improved bass response.

Klippel Verified: The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Rockford Fosgate optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.

VAST Surround: The Vertical Attach Surround Technique (VAST) increases a speaker's effective radiating cone area without increasing the size of the basket.

FlexFit 2 Basket: The FlexFit 2 frame utilizes slots (where possible) instead of single screw sized holes; allowing slight adjustment of the speaker when mounted.

Size Classification Note: Some manufacturers, including Rockford Fosgate, call this size speaker a 6-1/2". Because it requires a larger cutout than a standard 6-1/2" speaker, Crutchfield has traditionally referred to this size woofer as a 6-3/4". Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.

PEI Dome Tweeters: The 1" dome tweeters are made of Poly-Ether-Imide (PEI); PEI is a polymer film that produces a wide soundstage for superior imaging.

Mounting: The tweeters have multiple mounting configurations; choose flush or angled surface mount. The surface mount housing can be positioned at a 10° or 30° angle. Depending on the mount used, the installed dimensions are:

  Flush Surface 10° Surface 30°
Mounting Height 0.40" 1.064" 1.297"
Mounting Depth 0.912" Screw Depth Screw Depth
Frame Diameter 2.112" N/A N/A
Cutout Diameter 1.75" N/A N/A
Frame Width N/A 2.128" 2.128"
Frame Depth N/A 2.153" 2.149"

Crossovers: The high-pass crossovers are integrated into the baskets of the woofers and the tweeters are wired to a second set of terminals on the woofer using the included wire. The crossover slope is 12dB per octave.

Speaker Terminals: These speakers have 0.25" wide positive (+) terminals and 0.187" wide negative (-) terminals, which are too large for the vehicle-specific speaker harnesses Crutchfield supplies for many vehicle applications. We recommend that a pack of assorted female quick slides (item number 120FQS10PK, sold separately) be purchased and spliced to the harnesses to adapt them to the speaker terminals.

Q
Is it the tweeter that has the internal crossover, or is there a special connection on the mid-woofer for the tweeter to connect to? (P165-SI)
[ William  Feb 08, 2018 ]
2 answers
A
The crosover is built into the woofer, so just screw down wire connections from tweeter and good to go.
[ Richard  Feb 10, 2018 ]
A
It's the midwoofer that has a special connection to go to the tweeter. I just connected mine directly into my factory harness instead but it would probably sound better if I had used the special connection from the midwoofer to the tweeter.
