Fawk yea man, plenty of room for wires and such in the trim and engine bay. you ever have issues with your's idling down to like 350/400 rpms and staling out? mine has done this once, but it gets close quite often sitting at stop lights.

How old is your alt? Sounds like your alt is on it's way out.

it's only been in there for like 500 miles now at MOST! and the bearing is going out on it i'm pretty sure. it's still charging but i'm sure it's not doing an excellent job. it was just a cheaper alt off ebay, paid 240 for it shipped. World Power Systems or some ish.

word man thats what i usually do when I'm at lights or just parked up. Seems to happen more often right after i've been drivin her at high speeds/rmps. I knew the WJ's did it sometimes though before I bought it haha so I guess I knew it was comin at somepoint. I love how they sound idling at ~500rmps though. you got the 4.7?

If i didn't have the subs already... I did look at DC subs but they seemed out of my price range, was origianlly planning on type 4 15's when I seen these sundowns for a good price.

What sort of box are you putting the SA's in? Idk why everyone never bothers to ask this cuz its the most important part of power handling...

 

[Jerhemy 10+ year member]

i'll be making the box, 3/5" mdf, doubled up on the baffle, back. sides, and bottom of the box, seperated sub chambers, ~3.5 cubic feet before sub displacement. 38 sqaure inches port, 18 inches long, should be tuned to like 35 or 36 I think.

Its on the small side and tuned higher so they should be fine with over powering but watch them...

I think you'll be fine, just set your gains with a DMM or an o-scope. I feed my single SA-10 a minimum of 1200w and it takes it fine. Of course, they aren't always going to see that amount of power, which is what makes it just fine.

And is that 3.5 cubes for a pair of 15"???? o.0... before displacement????

 

[Jerhemy 10+ year member]

def meant 3/4" mdf, not 3/5".

so if I gave them more port/box volume and tuned lower I would run a higher risk of burnin one out? That makes sense though.

I listen to mostly rap and hip-hop so I figured 35hz would be a good tuning spot.

it'll be ~3.5 cubes PER sub, so ~7 total for the pair
