All my gear is for sale. Getting ready to rebuild. Any special flat wall design tips?

What year and model jeep is it again? We were building a 4 15" 4th order in a 97 grand cherokee. Dude got arrested and we never finished everything but the wall was in.

98 grand Cherokee. So they're both ZJ

He does NOT have enough room for 18s. He has 24-26 cube max. If he wants to keep things nice and square all around he has 33X40" internal dimensions on the baffle side. You'll have 300" ^2 of port without flaring out the sides coming up to the baffle and no way to mount 4 18s without angling them.... IMO not worth the trouble with so little airspace.


Check my build log. My only regrets are not using a few more layers on the baffle and back. Do 3 layers top bottom and sides 4 minimum on the back and 6 minimum on the front (I'm going to do 8 or 9 when I rebuild my baffle). Make the box as big as you can and keep it square all around (should give you roughly 24-26 cube), make the port as big as you can. You can very easily shrink the box and lengthen the port later if you want to experiment.

You're welcome to use my idea of a removable wall on the back so you can climb in and out to work, otherwise see if you can't angle out the sides towards the baffle to get a wide enough port to climb into.

If you have the money to buy subs all at once I'd still suggest grabbing those TRFs from the fella in California. I've sold to him in the past and he's a no BS guy to work with and you will not outperform those subs for the money AND with 2 18s you can easily keep all the sides of your box square and still have a large enough port to climb into to work. You could easily have 155 with those TRFs in a flat wall in your Jeep on 6-8K.

Putting batteries behind the front seat isn't optimum for the meter but It'll really help center the weight for a better ride. Do consider that, you can fit 4 group 34's behind your front seats.

theres a guy local selling 4 eclipse titanium 15s... id rather do that. I can't afford the TRF 18s. The eclipses are blown. So I would much prefer that. That way I can split the cost of woofers and recones.

3hp is an excellent platform but prepare to spend probably 125$ a pop to recone them, more if you want to get OEM TC metal cones. Coils, spider packs and cones will be 35$ for each give or take plus shipping and you'll need glue and solder. Patrick/Robot Underground may or may not have OEM coils to fit those motors still, that's where I got the last ones I used for that motor. Avoid OEM spiders even if you can find them. Those sewn in tinsels are the weak link on the 3" coil tc subs, they'll pop like a corn nut at about 3KW and may catch the spider on fire when they go off.

That all said if you're not paying more than 125 each for them broken you should grab them.
