Custom fit 5.25"s in rear deck - 81 Pontiac

[I Like Waffle]

This is a small build thread im doing for the sake of people that have the old *** GM cars with the 4x9 size speakers or whatever they are and cant find good rear replacements that bolt up.

1st pic - my infinity 5022i coaxs. Some decent coaxs i got from work for around 45-50$. Probably 50-60 at any online retailer. These speakers are by far the best 5 1/4 coaxs ive heard yet. Ive owned type r coaxs, phoenix gold, and a few others, and these are by far more clearer and have alot more midbass to them as well. They blend perfectly with my PG comps up front.

2nd pic - The weird size hole the car comes with. Measures 3 3/4 by 7. Obviously cant fit anything directly in there so this is where MDF comes in handy.

3rd pic - Me drawing everything out. I used the template that came with the speakers to measure the cutout holes, and traced a 6 1/2 plastic baffle i had laying around to round out the edges of the mdf baffles im making.

4th Pic - Another pic of the tracing. The baffles i made measure 10w x 5 3/4.

5th Pic - Everything drawn out and ready to cut

6th Pic - Always cut the edges first. MDF is kinda fragile //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Dont learn that the hard way like i did.

7th Pic - Baffle in place and being marked for trimming down. Had to take about 1/2 inch off 1 side and 1/4 on the other side

8th Pic - Baffle trimmed and painted, with speaker mounted in it. Ready to be put in car

9th pic - Just a pic of the baffle sitting in place where its gonna be. I know the rear deck looks kinda crappy. Its gonna be completely repaced eventually, but for now im just gonna do 2 coats of black over it.

10th Pic - Used liquid nails around the bottom, a small bead so it doesnt squeeze out everywhere. Wanted to make sure everything was sealed tight and didnt vibrate from the subs.

11th Pic- View under speaker with it sitting in the factory hole

12th Pic - View from under the speaker with 2 phillips head screws with 1 inch washers on each side securing it to the rear deck, and everything wired up.

Ill get pics of everything put back together and painted tommorow. Ran out of daylight today

This is my first "build" thread so hope it was informative to anyone who may have been needing this. Sort of a noob but im still learning so dont flame me for it. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Next week ill be attempting my first fiberglass build by putting a gps in the dash //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif Also look forward to an Active setup/ Infinite baffle/custom interior build with 2 15's in a 68 pontiac ill be posting in a few weeks //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
