Going active with the 9887

[krisfnbz 10+ year member]

Okay so I think I found the problem out. I think it was the RCA's.... somehow some way.

I just ran new Much better JL RCA's and I did not run them anywhere near any wiring other than the JL 9 wire to which my tweeters and mids are connected to the amp.

Im about to fire it up and see what the deal is. I think I finally figured this shyt out. Took me a couple of hours wiring and unwiring **** but lets see... give me 20 min.

I don't know about hooking up for active, but I do know the top preouts are the rears, and the middle pair is the fronts. It's in the manual.

Okay guys so I am finally getting MINIMAL noise to my speakers. You wouldnt be able to tell unless you had the car off and doors shut with pure isolation to the speakers.

RCA's was the problem I believe. Their is still some static at low volume, but its nothing that is critical like before.

Now I have to finish connecting everything. I already have the front end done. Now the rear and all..

Now I just need to set my gains for my tweets, mids and subs and find the right crossover points and were good to go.

Can you give a bit more detail about your setup? Are you running 3 way active without sub?

 

[krisfnbz 10+ year member]

Yeah.. are you running ative or passive?....

I registered just to say how good this thread was. I am going active on my 9887 this week, and all the testing and knowledge was helpful.

In that case I would bump up the low to 80 at 12 and adjust the sub level on the HU up to where they hit hard.

I almost blew my speakers running active yesterday.

Thinking of doing the same thing KRISFNBZ is doing and switching my 9813 out.

1.) Does the 9861 run active? or would i need the H-701 for that

2.) What is the big advantage of active? Is it really that great?

3.) My system is as follows right now....

Front Stage: CDT 6.5 comps (think CLA-61's)

Front Amp: Eclipse 36401 (60wx4 @ 2ohm; 40wX4 @4ohm)

Currently bridged to 2 channels.

Sub: 2 JL Audio 10''...soon either a single 10'' JL W3 or 6 or 10'' ID

Sub Amp: Kenwood

Thanks for any help...
