Not sure if this image of an OE DSP sub connector is any help in understanding????

RB, I'm lucky to say I've only ever er had the door panels off twice before this speaker install. For a new door handle and new window clips (both done within last 8 months). I never had any rattles from factory woofers. And I only get them now with certain frequencies. Door is still quite with stereo off and driving so nothing else rattles from road vibration thank god). Oh well time to take door panel off for a 4th time (but in no major rush). The mids and tweeters have me in music heaven. Even my SiriusXM radio sound quality has improved and that was my main objective. Music from my GROM or CD player (ewww what's that) sound great but even brighter now.

Glad you liked the mids Mike! You seem to have a good ear for audio so I am very much impressed to hear how much of a difference you are hearing

And SemcoMike thank you for posting those pics of the DSP amp, most helpful indeed, I will be doing more research and hopefully I can find a solution that doesn't take much modification, and can be wired up easily to keep the OEM DSP amp happy -

RB,

It looks like each channel of the DSP sub is receiving a separate channel from the amp, given the four twisted pair wiring connections

Yep - which actually goes up to my comment above from the E39 boards - "each voice coil is hooked up to a separate channel of the DSP amp getting 40w approximately per channel at 8ohm impedance) -

Now if only I could figure out how to get two 4ohm single voice coil subs wired up so that the amp would see an 8ohm load at the same wattage, we'd be in business - or so I think.

ok, you didn't ask for it, but I'm gonna give it anyhow... my review of adding two Fountek speakers in dashboard and a JL C2-600 set in front doors with factory mid bass and mid range still in rear doors with a DSP system (and I have always had a 10" aftermarket sub and amp (I can't recall if I tapped my LOC into the wire harness signal going INTO factory amp (ie pre-crossover signals) OR wires going FROM factory amp (ie signals already put through factory crossovers).

Music selection:
a LOT of EDM and Movie Scores/Orchestra (talk about A-Z spectrum)

Music Source:
I RARELY use my CD player (probably best sound source tho to perform testing) but I do use my GROM (with 320kbps MP3's) and SiriusXM Sat radio (WORST quality to do this review with BUT gave me the biggest difference in audio quality which is what I was going after).

The change of the mid range and tweeters was day compared to night. I say day first because now the sounds coming from those 4 speakers are bright and not muddled or sounding dull/lacking vocals.
I have never thought the mid bass speakers were an issue with sound quality as they play decent bass frequencies without distortion and I don't rely/expect them to do what a mid range and tweeter should do. AND so after I installed the Mid Range, Tweeters and Mid Bass I didn't notice a difference in what sounds were reproduced with the C2-600W (woofers) speakers compared to the factory mid bass and therefore thought I wasted many hours on making the speaker swap.

after a few days of driving, I thought why not compare the factory rear door speakers to the new front door/dash speakers so this morning I had a sound off using the FADE buttons on MID... I have to admit now the new C2-600W speakers make a LOT more sound of higher quality (less bass in my opinion) but they play the 80-800hz range (with an emphasis on the 200-800hz range) much cleaner than the factory did. the factory rear mid ranges are disgusting dull sound now compared to the Fountek (and most likely the added sounds of the tweeters as I can not separate where the 2 new sets of speakers overlap)

Since I drive and am never in back seat and rarely have passengers who will appreciate the upgraded sound, I'm debating not even putting the JL C2-600W OR Fountek speakers, I just bought from semcoinc, IN the rear and leaving it as is. The Front speakers steal ALL attention.

Hi Clockwork,



However, with the caveat that I got a nice improvement in the rear door woofers by using the budget priced Dayton Audio units combined with C2 tweeters.

Likewise, I stream a fair amount of EDM and appreciate the new found crispness and clarity that the new mids and tweeters have brought to the party and the low end clarity that the C2s bring.

I don't ride in the rear seats either but I can hear the benefit of my modest speaker upgrade investment back there

Mike

PS: Thanks for the subwoofer wiring link. That was really helpful.

Semcoinc, the more I think of it, I will be installing the Fountek's in the rear doors cause I really enjoy their upgrade so I may as well spend a few hours on the mid bass to then and let the silicon dry as I replace the window regulator clips and sliders.

^Agreed Mike - I would definitely tend to the regulator clip and slider clip (1 of each on the rear doors) while you are upgrading the speakers - door carriers if necessary but I don't feel that those carriers tend to go as often as the fronts (from lack of use maybe)
