Going active with the 9887

[krisfnbz 10+ year member]

It's really the same as running active with any other.
The 9887 has a nice feature for the tweeter, it automatically sets the tweeter at 4khz so that you don't blow it, but of course that is as long as you connect it to the correct outputs. The crossovers and eq's can be stored in 1 - 6, when you disconnect power to the radio those settings stay saved.

Because the tweeters wouldnt want anything lower than 4khz correct?

No, 4khz is just to be safe, my tweets for instance are crossed at 2khz, but some cannot go that low.

Makes sense. On my 9883 now I have the "Bass" set to 60hz and the "Treble" set to I believe 15khz, but thats all I really can do with this HU.

It is based on the manual, but something is either wrong with mine, or its some type of a fluke. My mids are on the middle, my tweets are on the top.

i could be wrong but i remember hooking up the front to the tweets and the rear to the mids and all i could hear were the highs playing and no mid bass at all. i ended up switching the rca cables on my amp and it fixed the problem.

i wold go out and check my unit but it's a ***** getting to it.

oh and for the output, the top is labeled rear, middle is front and bottom is sub. check page 40 on the manual.

funny how when I check the manual that the top is labled rear, but on the unit itself I could havw swore I saw it said front on the top. let me check again.

EDIT: on the unit itself the top is acctually rear, the 2nd rca's is front and bottom sub.

if your tweets are on the top, then its under "rear" and if your mids are in the middle than its under "front"

that's how i have mine setup.

Good info here. I'm in the same boat, but with a 9835. Trying to learn as much as possible before I go out and do it. Good luck to you.

Okay but how about this question guys.

I had the 9883 previously installed. I had that wiring harness from the 9883 connected all taped and shit. I think I wouldnt have to use the new harness with the 9887 because they are both alpines! the only thing I see different is on the yellow wire on the 9887 wire their seems to be a "box", that the 9883's harness did not have.

And the wire fits into the 9887 just like it suppost to.

I would change the harness, the box is a 1) relay, or 2) fuse or 3) noise filter. Better to protect your investment.

i believe that the yellow wire and fuse box is the power line.
