Hi all, new member and joined after spending a few frustrating nights trying to figure out what to do.
I have a 2000 model p38, missing the DSP, CD changer and sub in the back. An aftermarket head unit is currently running all the original speakers but, obviously, it doesn't sound the greatest. So, question/s; do I buy an aftermarket dsp and amp and plug it in to the existing left over wiring from the original dsp or, do I just pull the whole lot out and go aftermarket speakers and amp? I also have a zeroflex sub/amp I can use. If it's better to bang in an aftermarket dsp, any recommendations or advice would be very much appreciated. Thanks all.

If the DSP amp has been removed, then the wiring should have been linked where the DSP amp originally lived (see https://rangerovers.pub/topic/8-info-p38-alpine-dsp-amp-connections-and-wiring?page=1#pid30814) unless someone has run new cabling in from the head unit to the speakers. What you have now will dictate what you need to do and what is the least work. Most, if not all, modern head units have built in DSP anyway so an external DSP amp (if you can even find one) isn't worth it.

Your original speakers are now 24 years old and speaker technology has improved a lot since then, they are also likely on their last legs anyway. I've replaced all of mine with JBL units (JBL Stage 600CE), far better and a straight swap. If you want to add a sub, then up to you, I've got a small underseat one sitting just behind the BeCM under the drivers seat and that works well too.

Are these the speakers?

I guess that I need two pairs so I can do the rear doors as well ,

Yup, they're the ones.

Yep, no new speaker wire to the speakers, at least in the driver's door and the wiring is still in the back from the dsp so I'm presuming that's all been hooked up to the sony head unit. I almost bought new speakers at the weekend and then didn't. I though about putting an amp in the back where the original gubbins were. My question is though, and to be fair I'm just about to check your speaker link, but, did you replace all your speakers for like or were they a component speaker?
Thanks for the info too, makes more sense than I've read so far.

The JBL speakers come as a pair of 6.5 inch ones and a pair of tweeters. I replaced the front tweeters with the JBL ones but with my old ears I couldn't hear any difference. What you will have now, assuming they haven't been messed around with, is a pair of 6.5 inch woofers and a pair of smaller midrange speakers in the door panels along with the tweeters in the triangular panel. The rear doors will be the same but without the tweeters. I didn't touch the midrange, they are still the originals. The tweeters and midrange speakers are in parallel and fed with the higher frequencies, while the woofers come from the DSP amp on a lower frequency output. That is how you would wire them if using crossovers.

The original woofers are attached to a plastic support with bits of bent tin, the JBL speakers need screws but not a problem to just drill 4 holes in the plastic support and use self tappers.
