I just installed a Audison DSP/Amplifier using all the outputs from the bose amp to the Audison dsp, it unfilters the signals to a flat. I've been tuning it and sounds damn good. Audison speakers and rockford subwoofer (might change). Lots of wiring and soldering.
Through the grommet in the firewall. Cut the hole for the main harness for a little extra room. I used an electrical that runs wire to get it passed the grommet.
I changed mine out to Audison speakers with Rockford Sub, on the Bose system. Sound deadening on all doors. Next is an Audison amp install, just waiting for it to get cooler out here in Miami.
Just received my TSP downpipe. Installed myself, fit perfect with AWE Touring exhaust. No issues. Replaced bolts and nuts with the titanium ones. Spray Krill oil worked great for stock bolt removal.
Take the molding and kick panel off it should be there. Then twist lock it back into top of the kick panel to lock it in. Put kick panel back on then molding.
Small knife just push the wiring harness to the side. If the grommet comes off, just push from inside and pull the tabs on it from engine bay. Not really hard, I stuck the tool to run wires and taped it, pulled through.
I just cut a small hole in the main grommet in engine bay front of driver. I fit a 4 gauge power wire. Grounded in back where there's a ground already under rear latch panel.
Connector you posted is for the 6.5, but I cant find any for the tweeters, in which some were recommended but still did not fit.
I installed hertz tweeters with Audison mids. Coming up with a plan to bypass Bose amp and put in a DSP/Amp.
Great review. I did my own with the same sub, but added a powered Rockford Fosgate 12 inch subwoofer. Takes space but has an easy disconnect.
Pic of the audiocontrol sub with a cheap install ring from Amazon. I was able to keep the stock speaker grill for the sub. It is almost nonexistent...
The two metal hooks for securing on each side have a plastic cover, lift up with a screwdriver, then there's a phillips head screw that needs to come out. After that cover can be carried out.
Hope that helps.
