Custom car audio

Weather was better today, got some more work done.

Getting close now... I guess I need to plan to actually buy the sub now.

Getting closer!!! 

I found out something interesting about JL Audio... apparently the designers on the JX line (the entry level amp line) are not involved so much.

Looking awesome so far!!

Getting there. Still two steps to be done:

1. Modify the factory subfloor
2. Get new carpet and cut to fit.

It got too damn hot today, it's over 30C/86F. I guess I need to be patient...

That's a JL Audio RD 500/1, and a Soundstream PN4.520d - I managed to just barely get both of them to fit. As configured, it's 900 watts total (100x4 and 500x1.)

[danf]

OK. So I modified the subfloor and made sure it's level with the floor. At least if stuff slides around it won't damage anything.

New carpet. Finally done... Now I can put stuff in the hatch besides stereo stuff! 

Also attached my old install. It's not very clear in the picture but the box was about 1.75" below the tops of the plastic shock cap. So there was maybe 3-4 inches from the top of the subs to the cover. 

By the way, that single 10" sub pounds. I can't believe how low it can go given it's in a .5 cu ft sealed box. It's quite insane actually. I can actually bit a large duffel in there now, that other bag I had to squish to 1/3 it's size to fit in there.

Nice work, id get rid of my rear seat before i took out the spare though...  Ive never needed a spare (knock on wood) but i always carry one anyway.

My car never had a spare when I got it. So I put the other sub box (custom 'glassed in the spare tire well as well) there. I've had a flat actually but it was in my driveway. I also have *AA in case I need assistance.

nice! I do missing having crazy audio. I remember the early 00's being common to build crazy setups. What's the RMS on the amp going to the sub?

[danf]

The 500/1 puts out 500 watts RMS @ 2 ohm. It's a DVC 4 ohm sub.

[Sigma Projects]

Oh shit, that must really bump hard. I used to have two 12" subs that were ran with 250 RMS each and they were pretty killer, but these new subs are just so much better like you said. I can imagine that 10" with 500 RMS running through it must make the whole car lift off the ground, might want to point the sub out the back for extra boost

Is that enough box space for a sub that powerful?

Believe it or not, it is... this sub was designed for small spaces. JL Audio recommends 0.4 cubic feet for a sealed box (0.5 cubic feet with the subwoofer displacement) and that's what I built this box to. It's (the subwoofer) actually only rated at 400 wrms, but I was told this combination will be fine. 

I set it up more more SQ, not SPL. I'm not really interested in the boomy bass anymore. That said, I've been listening to Linkin Park and it sounds good. You can hear the bass but it's not overpowering the fronts.

Then I played some early 90s dance tracks and holy can that single sub pound when it has to. I was playing "Whoomp! There it is!" off of some dance CD and I could feel my hair moving (or what's left of my hair  ).  Coming from 90s car audio, that would be like impossible back then! I'm impressed with that single sub. Don't regret yanking that big ass sub box out at all. It's nice being able to put something other than a newspaper in my hatch.

That's quite nice. Yea, it's great how much better acoustic technology has gotten. Except for PC setups, at least to me. Can't find decent setups anymore replace my really old Altec Lansing system.
