Wiring between front compartment & inside

[tolum]

Guys;

I should receive my new Alpine amplifier in few days. I would like to route wiring between my Alpine radio and the front compartement where the amplifier will take place. No problem for (+) & (-), very easy with battery next to the amplifier, but I have to route a pair of RCA cable from back of my radio to the amplifier. I'm sure, lot's of people here did it, so I'm asking to you guys where did you cross the fire wall between inside car & front compartment? Did you drill a new hole? Where? Or did you cross the wall somewhere across an existing rubber grommet?

Thanks for sharing your experience.

There is a rubber grommet just above the gas pedal that leads to the battery tray compartment (moat). Cut an "X" in the grommet towards the top and run RCA wire thru from the battery side. Have a partner assist as to not push the rubber grommet all the way thru. Depending on all long your RCA cables are you can run under battery and into the trunk area where CD changer normally sits or take a shorter route into the trunk area by the brake fluid reservoir. Use cinch ties to neatly secure cables and use sealant to seal the cut in the grommet.

Thanks Lbrandsm, I found it and wiring is done.

On that note... I've always wondered how you're supossed to run new "speaker" wire from your door speakers if you're hooking up aftermarket amps? It's not like you put in the door wiring harness as it's all sealed in rubber. How have others done this?

I'm not sure I will answer your question, but personally, I'm using the existing wiring. Factory speaker wiring is going from speakers (doors + dash mounted) to the OEM amplifier plug in the front trunk. So knowing the color codes, I welded new wires from there and route it to the new amplifier I installed.

Hmmm.... yea, basically, I plan to finish mine a little different, so i don't know if i need to run new speaker wire or not. Right now the current architecture is setup as follows:

Front Dash - MB Quartz PVI-210 4" woofers and 1.6" Tweeters hooked to a MB Quartz crossover on each side

Rear Speaker Upgrade - Has been upgraded to 4 JL Audio TR-350x speakers (and I don't know the what the factory amp outs on these are)

Door Speakers - have JL Audio ZR-650 Woofers hooked to the JL Audio crossovers on each side

There's a really crappy Jensen head that someone installed before I got the car

The Porsche factory DSP module was somehow hooked to this module

The Porsche factory amp still remains

What I'm TRYING to do is the following:

Replace the crappy jensen head unit with the Alpine IVA-W203 + P1NAV

Remove the Porsche factory DSP Module, and move the A/C controls in it's place, replace with the alpine PXA-H100 Imprint Module.

Remove the single Porsche Factory Amp and replace with 2 amps... a JL 300/4 (4 channel) and a JL 300 / 2 (2 Channel).

In regards to the amps themselves, I would like to wire them as follows:

Front Dash MB Quartz will be run to the Front Inputs on the 300 / 4 amp, using 2 channels.

Rear Speaker Deck will be run to the Rear Inputs on the 300 / 4 amp, using 2 channels.

Door Speakers will be run to the Inputs on the 300 / 2 amp.

Thus the breakout is as follows:

Fronts Speakers will consume 75 watts per side

Rear Speakers will consume 37.5 watts per speaker

Door speakers will receive 150 watts per speaker

I'm not sure what all the pin-outs are.
