Hi All -
I'm somewhat new to car audio, but I'm doing my part to get up to speed. I'm reading lots from the Tutorials / Forums, but still need some help and advice... so thanks in advance for your replies.
Goal: I'm going for good clean sound, not trying to build a competition system, piss of my neighbors, make my ears bleed, etc.
Cost: I have money, I'm willing to spend some, maybe around $1000. Again, not trying to build a competition system, just want great sound.
- I have an old Kenwood KAC-606 AMP (2x 50W or 1x 150W bridged) with a 10" Infinity Sub in a bandpass enclosure. This combination was extremely loud in my old Integra, people thought I had a couple of 15's in my trunk. I'd like to use the AMP, and maybe the enclosure to save money, but it's a poor fit in front of the rear strut and probably too loud. Ultimately I will probably favor replacing it. Maybe I can use the existing 10" speaker in a new sealed enclosure. Recommendations welcome.
- Replace factory headunit with Pioneer DEH-P6900UB CD Receiver to gain iPOD functionality. Reviews on this unit are pretty good in comparison to some like models from other manufacturers.
- The front speakers don't sound too bad to me, but then again, I've never had anything but stock speakers in my previous cars. If I replace them, I'm planning on the Polk Audio db6500 6-1/2" Component System.
- The rear speakers suck ass and I'd like to replace them, though I've already read that this won't improve staging and is probably a waste of money. Opinions welcome. If you think I should replace the rear speakers, please recommend a set of Polks that would work.
Procedures I'm planning to use:
Dash Removal & Head Unit Installation
Center Console Removal
Rear Panel Removal
Only if I'm going to replace the rear speakers or if needed to access the Bose Subwoofer Cubby behind the drivers seat. Can I just pull off the stock panel to reach that cubby without removing anything else?
Front Speaker Wire Routing Using Factory Harness & Wire Loom
In the 2007 350z, the inside part of the wiring harness is not readily accessible, but up behind the front dash. The dash looks like it might be able to be removed with 3 bolts, one near the power outlet, one under the bottom right corner, and one in the airvent leading to the door jam. Does anyone know this to be true? I have not seen instructions for the 2007. Should I be concerned about deploying my front airbag? I'd like to avoid that for obvious reasons. If I can't take off the front dash, I can still get to the inside harness, but it will be difficult at best.
Front Component Speaker & Crossover Installation
In the 2007 350z, I think the door removal instructions might be different than shown in this link. I've pulled up on the rear part of the 'armrest' on both doors and I hear it pop, but the piece doesn't want to pull out. On the drivers side, I don't have a 'plastic cup' in the door handle with a screw in the bottom, the 'plastic cup' in the door handle is 'bottomless' and goes straight through. Not sure how to get my door planels off. If/when I do get them off, I'd like to know if anyone knows if the Polk Components mentioned above will fit without spacers to avoid my windows. Also, is there room for the crossover and clearance to remount the door panels?
Install New Tweeters in Factory Tweeter Location
- Excellent pictures and descriptions on this page, to complement the procedures above.
I figure I'll need a 4-channel amp to run the 2 front components and 2 rears (unless I don't bother with the rear speakers), then I can use my old Kenwood to power a 10" in sub (maybe) if it will provide enough power to whatever sub I wind up with. I'd like to mount both if possible in the Bose Subwoofer Cubby behind the drivers seat. I'd like to build an amp rack in there, so if you have dimensions can you please post them? If anyone has any advice about what combination of amps to get, please share your thoughts. Or maybe I should skip the rear speakers and consolidate down to a single amp mounted under the front passenger seat to make it more accessible. Manufacturer... Kenwood, Alpine, Profile (more bang for the buck unless you have problems)... please share your experiences.
JL Sealed Enclosure (Custom Fit)
This is by far the nicest enclosure I've seen yet. A good use of the wasted space between the bulkhead and rear strut, and still leaves you room in the trunk. The box also bolts down so it's not going anywhere. Too bad this thing is $800 retail, probably $600 best price. I'm told the two 10" JLs in the box are $200/each. I think it's too much money. Anybody seen something like this for less money? Also, I probably only need 1 10" sub in the back, 2 would probably be overkill since the 350z has such a small cabin already.
Any other advice you can offer is much appreciated. Again, I plan to start purchasing and installing within the next week or so, so I will post pictures of the process for those who haven't touched their 2007's yet, and daytime pictures of the final install once complete.
