To interconnect the Logic7 underseat woofers output to this amp you either need to get a Blaupunkt PnP harness (and cut the speaker connector that plugs into this amp) or a separate Line Output Converter (LOC) with a built in 12V remote turn on line.

Example:

- Get this PnP harness ($24.99)... http://www.crutchfield.com/App/Produ...PNP017&tp=6348

... and cut the 4 speaker wires input connector to the amp; that's the only connector that you need. You may be asking yourself "what a waste of $25.00". The trick here is that by wiring the Logic7 OEM amp underseat woofers output wires (4) into this PnP connector the THA 275 amp will "sense" the output of the OEM amp and then turn on. No need for a separate remote turn on wire, or RCA cables.

There is no signal sensing circuitry at the RCA inputs of this amp, only at the PnP speaker level connector input. That's the reason you will need that PnP connector in particular. You could use a pair of 4 pin Molex connectors instead of just cutting the Logic7 speaker outputs so you can be able to return the system to stock at any time.

If you get a decent 2-channel LOC with remote turn on to do the exact same connection you could spend some $30.00 in the LOC, will have to make a 12V and a ground connection to the LOC and will have to get an stereo RCA cable to connect the LOC to the THA 275.

This set up done right will be able to give you a radical bass improvement over the OEM woofers, and a very nice complement to the rest of the Logic7 system. I would say, most of the E9x owners will be satisfied with this upgrade over getting a trunk sub.

Reading back in an earlier post by Technic, it would appear that you dont necessarily have to have the PnP harness, it sounds as if any connector which fits the PnP input of the Blaupunkt amp would suffice. Hopefully, trying to find a connector that fits teh blaupunkt amp isnt difficult. I wonder if Radio shack has anything...

Hopefully Technic will chime in. I should hopefully still be able to send the harness back to Crutchfield!!

So anyone with this harness... can you tell me if it has all speaker outputs? So can i tap into the front speakers and so on.

My mistake: return the PnP harness to Crutchfield, as it requires this PnP extension cable: http://www.crutchfield.com/p_023THA2...ension&tp=2472

The connector to plug into the THA275 is in that extension cable.

I don't think that it is cost effective to get that $60.00 cable to just cut the connector. A female Molex pin should be able to fit that THA275 PnP connector jack.

I apologize for this major oversight of my part...

[Technic]

Fixed all the mistakes...

[pdjafari]

haha no problem at all man!! we're all human after all!! crutchfield customer service FTW!!

[techforge]

If you figure out what molex connectors work and where to get them post it up. I've had the subs for a few weeks and I was about to order the amp and harness.

[pdjafari]

I think these might work.



Going to radio shack tomorrow, I'll post pics and keep you guys informed.

Cool thx

[scampos1984]

For sure there are Molex connectors that work for the Blaupunkt amps, I know a guy who installed them. I don't know the reference of them, but there are :-D

The female Molex pins could work but not the Molex plastic connector...

OK, I ordered the Blaupunkt THA1250PnP from Crutchfield for $180 after coupon. Pretty good deal on this amp. It is a mono amp so I will wire my two SWS-8 4 ohm woofers (also bought this week) in parallel, which will give the amp a 2 ohm load. At that impedance, it puts out 300W, so 150W per woofer which is perfect. I know I would not be satisfied with 75 or 90W of the smaller amp, and for only $50 more, I think it is a wise investment.

Yep, I would only be using the pins not the plastic connector. I would imagine the only plastic connector which would be an exact match would be from that extension harness crutchfield sells for $60!!

UPDATE

Went to radio shack and bought the female connectors. They were too big/loose so I had to 'crush' them with a pair of pliers slightly. They fit on their snug now, but the other issue is they have no wrapping/tubing to prevent an occasional 'touch'. I am looking to find some heat shrink tubing or perhaps I may just wrap the ends with electrical tape to prevent them touching once they are inserted. I was thinking maybe to purchase the real working harness for $45 then selling off the ends to whomever needs one for like $5 shipped lol...

I thought it was $60?

Technic found it elsewhere for $45, I called crutchfield as I sent the original back and they wouldnt price match....

[techforge]

I might just get that and be done with it. I like solid clean connections in my wiring.

[pdjafari]

So I bit the bullet and ordered the harness around $51 shipped to VA. Anybody wants the extra connector $20 shipped and its all yours....

[techforge]

Don't you need 2 connectors - one for line in plug and the other for line out to speakers?

Line out plug adapter comes with the amp.

It actually did come with mine !!

Good News!!

I think I've found a CHEAP solution!!! I removed the output connector that comes with the Blaupunkt amp and is plugged into the LS output jack. I examined it closely and found very small serial numbers on the sides which I then search on google for. There was also a company logo with a P but I was unfamiliar with which company it was from. After some online research, I was able to find the manufacturer of these plugs which even provides these connectors for Blaupunkt among many other companies...

The numbers were IC 2.5 (which is the maximum wire entry diameter for a solid wire) and below that 5.08 (which is the pitch or distance between each of the connectors). The last important tidbit is the # of positions/pins.

On the opposite side the numbers read PA66-FR.

These connectors are manufactured by Phoenix Contact which is also has US HQ in Pennsylvania.

I've found a website which sells them here but it's becoming difficult to get a price...

http://www.phoenixcontact.com/

I've found this other site which lists their price but its hard to tell from the angle of the picture if its the right connector...
