Thread: P38 Subwoofer Replacement

Hi all,
The sub in my 97 Rangie has been sick for a while now, so yesterday I took the time to remove the cd stacker and sub box to access the 8" sub spkr.
Talk about sick, the entire flexible part that normally connects the cone to the frame was completely gone and in bits at the bottom of the sub box.

I intend to replace with a same spec spkr and was wondering if anyone out there can tell me the exact spec of the standard speaker so that I can match one and ensure that I don't damage the matched amp

From what I can tell the original speaker is an 8" dual voice coil, but not sure on the impedance and watts. anyone out there know this additional info? Have done numerous searches on the web but can't seem to locate the specs.

Thanks,
Dean

Ok,

Here's my solution.

Followed wanglemoose's advice below and went to Jaycar today.
Bought a single voice coil 60w rms sub.

Now to wire as single voice coil by using the dual voice coil amp output I did the following.

1. Assuming an approximate 20w rms output from the amp I purchased 4 500uF capacitors.
2. I soldered one to each of the 4 wires coming from the amp and then joined the free terminals of capacitors joined to positive cables from each twisted pair to each other and similarly each negative cable to each other.
3. I then following the same polarity soldered a cable from the negative and the positive pair of capacitors to the same terminals on the new speaker.

Here is a basic wiring diagram.

Works really well.

Hope this helps others.
