A valuable installation tool

The following review is for SA68, which is a part of the bundle you are viewing.

Worked very well when putting Polk DXi 6.5s in my 98 Ford Ranger. Not very thick plastic, but that worked for me, since I didn't have much room behind the factory door panel. They are way more convenient than making your own adapter. You'll have to drill your own holes for the speaker mounts, and/or dremel them out a tad if your speakers need a larger cutout, but I used the measurements beforehand and they worked perfectly. Very nice.

These adapters are not usable for most speakers

The following review is for SA68, which is a part of the bundle you are viewing.

I was trying to use these to install speakers in my 09' Ford Escape. The mounting holes are correct but the speaker cutout is not big enough. Not sure what they used to model the design but not usable for most speakers. The description says they are for 6 1/2" but hole size is undersized. I ended up making my own using 1/2" plywood at a fraction of the cost.

Time saving, great value......

The following review is for SA68, which is a part of the bundle you are viewing.

I have been installing car audio for years. I would recommend this product to any amateur or expert installer. This was very easy to install and cuts time, compared to creating adapter out of ABS plastic. I have installed in several ford vehicles and was a perfect fit for the application. Thanks!

high quality product!

The following review is for SA68, which is a part of the bundle you are viewing.

This product was made with quality. But unfortunately for me the units were made to thick to install in my 07' Mazda speed 3 door panels. Other than that, my shipments arrived on time and in perfect condition. Would order from again!

Clean fit.

The following review is for SA68, which is a part of the bundle you are viewing.

Installed in a 2005 Ford F150 FX4 supercab.

Clean installation with the Clarion SRG1621R i bought from this website as well, with no cutting or drilling.

Good Adapter!

The following review is for SA68, which is a part of the bundle you are viewing.

Was able to tap new holes in the plate for mounting a 6.5" woofer (Polk MM 6501) in the doors of my 2014 Mustang. Perfect fit to the factory mounting location.

Good

The following review is for SA68, which is a part of the bundle you are viewing.

These fit my 6.5 inch coaxials in the cutout like they said. I did have to carefully drill new holes where this particular speaker needed to be mounted and it turned out well. There may be some 6.5's that won't fit in the opening, but mine did. They fit the 6x8 opening in the truck perfectly and the screw openings were right on the money.

Good speaker adapter

The following review is for SA68, which is a part of the bundle you are viewing.

I use this with 5.25 inch speakers in the rear of a 1996 Ford F150. It holds the speakers in 6x8 hole very well, but just make sure you use larger screws. To completely seal the speakers, I'd recommend using Dynamat or a similar product to cover the adapter. I also used this with Pioneer 6.5s.

Good product, ok fit.

The following review is for SA68, which is a part of the bundle you are viewing.

Pretty basic item here. Solid thickness on the mounts. Did not fit great on my 2008 Ford Mustang. I had to force it in place, but it did go in with some effort. Speaker openings were the right size.

My concern.

The following review is for SA68, which is a part of the bundle you are viewing.

In my own experience with this product i'm not feel comfortable because I ordered the Scosche SA68 Adapters for my kicker RS65.2 component but it didn't fit. The holes are smaller than my kickers.

Cool adapters

The following review is for SA68, which is a part of the bundle you are viewing.

They didn't fit exactly 100% and that extra thickness pushed the speaker out so the stock grill could not fit. But with some cutting and shaving i got it to fit perfectly! The speaker did fit in it well which was the main thing.

Made me look talented!!!

The following review is for SA68, which is a part of the bundle you are viewing.

I used these on my Ford Expedition, fit great! I see some people had trouble fitting their 6.5" speakers in, but my Alpine 610's and 610c's fit in easily. For a brief moment I felt like an installer! (They wanted a $100 to put them in. I couldn't afford it.)

Adapter for 6 x 9 car speakers.

The following review is for SA68, which is a part of the bundle you are viewing.

Although the speakers were a different size than I had originally planned, I was still able to modify these adapters to fit my application. Just having something sturdy to mount the speakers to before fitting them into the car door is very helpful. Great quality product overall.

Great Price. Very durable design. I went looking all over locally to find these at a store. Come to find that NO stores in my area carried ANYTHING like this. Worked Like a Charm Fitting My Speakers to my New car after taking them out of my old one.

Cutting required for 6-1/2" speakers

The following review is for SA68, which is a part of the bundle you are viewing.

The plates are ready to go if you plan to install 5-1/4" speakers; however you will need a jigsaw to cut the hole bigger if you want to install 6-1/2" speakers.

Cheap, easy and high quality

The following review is for SA68, which is a part of the bundle you are viewing.

Very good way to get better sound quality out of you're speakers. I ,like many, prefer and feel that round speakers have a better sound quality than oval ones. A lot of cars only have oval slots for speakers and this is an easy way to solve that problem.

May Not Fit

The following review is for SA68, which is a part of the bundle you are viewing.

I bought these to replace a 6x8" speaker with a 6.5" speaker. Unfortunately this bracket is not sufficient, at least for the speaker I chose (JL Audio TR650-CSi). The cut out on the Scosche is a 5" diameter. However, the speaker requires a 5 5/8" diameter. You can modify the bracket by using a dremel or other type of tool to widen the cut-out diameter. However, this would only leave me with about 1/16" on either end after enlarging it enough for the speaker...might as well cut it in half at that point (total height is 5 11/16" on the bracket).

It seems like it would be perfect for a 5 1/4" speaker some 6.5" speakers as well. You just need to make sure it is not too small, otherwise you are better off making your own bracket. All that being said, it is well made and I would recommend it under the proper circumstances.

Did not fit my 6.5in speakers

The following review is for SA68, which is a part of the bundle you are viewing.

Ordered a set to go along w/ my 6.5in speakers. The speakers were too large for the hole on the SA68. I had to trace the diameter of the speaker on to the SA68s and use a dremel to cut out the difference

Does the job

The following review is for SA68, which is a part of the bundle you are viewing.

What can I say, if you need an adapter to fit your 5 1/4 speakers into a 6x8 opening this is the perfect thing. However, it is hard to fit 6 1/2 inch speakers and requires drilling new holes

Do your research

The following review is for SA68, which is a part of the bundle you are viewing.

These are very good adapters, however i had to modify them for my JL C650 speakers. I didnt do enough research to make sure i was getting the correct ones. But even modifying them was a breeze and they worked great and were a perfect fit in my truck.

Will not work on 6 1/2 inch speakers

The following review is for SA68, which is a part of the bundle you are viewing.

These adaptors are recommended to mount round 6 1/2 inch speakers in oval 6x8 mounts(2013 f150) . The holes for speakets are not big enough and there is not enough material to cut out and make work. Had to return for credit.

ok for rear fill

The following review is for DXi521, which is a part of the bundle you are viewing.

I bought these because the ones we bought for our Mazda 6 sounded great (they were 6.5)... this pair paled in comparison. They sound ok as rear fill when singled out but that's it I wouldn't rely on them for much more than that. Given their size and rating I expected more butt should have known better. Either way hard to beat for the price. Would I buy them again probably not. Next time I'll buy a set of 6" mid basses and make them work.

Sound good

The following review is for DXi521, which is a part of the bundle you are viewing.

These speakers sound very good. I used them for a boombox project and they sound really good, couldn't ask for more. People say they have no bass but they have bass you would expect from a 5 inch speakers. Bass won't disappoint you. You won't regret buying these speakers. That's coming from someone who is picky.
