I have a couple questions for the rear side panel speakers.

I'm replacing my whole system in my 06 coupe. I know you need spacers when you install the front components. I have read both no and yes to needing spacers when installing aftermarket rear side 6.5's coaxials.

And another thing, do you guys add any kind of insulation besides sound deadening in the rear side panels? I have read that the speakers just sitting in air and don't sound that good, to much space around them.

I have a question also about the rear deck 6 x 9's. The guys that don't use them, do you just leave them there or do you take them out and just leave the covers on. And if you just leave the covers on without the speakers do you fill it in with anything or just leave the hole there?

I'm trying to read as much as I can, but it's hard when you have all these different opinions on what to do and what not to do.

These are the parts I have right now and are in the mail coming my way.

NEW JDM Infiniti G35 Double Din Kit w factory nav trim
Pioneer - AVH-P4300DVD
DLS UP 6i 6.5" 2 way component system
Metra 40-NI10 Nissan Antnna Adapter
Metra 70-7550 Radio Wiring Harness
Pioneer CD-IU51V AV iPod/iPhone Cable
PAC SWI-PS Pioneer and Sony Universal Steering Wheel Radio Interface

Been deciding on what amps, sub and coaxials to order and so far I have decided on.

JL10w6v2 sub
Alpine PDX-M6 for the Sub
Alpine PDX--F4 or Alpine PDX-F6

The DLS are 150 rms/ 180 watt max, the PDX-F4 is 100 watt x 4. The PDX-M6 is 150 watts x 4 which would seem to make more sense to use with the DLS's.

Not sure about the coaxials but will probably stick with DLS's since I'm using them in the front.

Will be sound deadening the front doors, trunk and more the likely the rear side panels and something to fill the rear side panels with.

Should I also buy my own Amplifier installation kits and Distribution block plus whatever else is needed or just get it at the place that installing my system?

Any suggestions would be great.

Thanks

 

The thing is, some of what you're asking is simply personal preference. I'm a huge fan of building a soundstage that sounds like the artist is performing in front of me. That works great in my home. It's the way music generally is experienced in a live setting.

The thing is, in cars we've all gotten used to hearing the music playing from all different directions. When I first heard the "front soundstage" option in my wife's G37 sedan, it was tough to get used to...despite being used to listening to my phenomenal two-channel + sub home stereo system. After a couple of weeks though, I'll never go back to having music blaring from every factory speaker hole in a car.

I'd recommend starting out with just the front components you've ordered, and the sub. Give it two or three weeks to grow on you, then decide for yourself if you want to add speakers in the rear side panels. There's a good chance you won't, if you're an audiophile.

Regarding the rear 6x9's. I measured the sound output from my sub before and after removal, playing the same passage in a song, and found that bass reaching the instrument panel (where I'd positioned the meter for both tests) increased by 10-15 dB. Since 10 dB is what is generally perceived as a doubling of sound level, I found it worthwhile to spend the hour to remove the factory 6x9's.

I left the Bose speaker covers on the rear deck. No point just having untidy holes back there.

I hope this is helpful. I agree there's a lot of conflicting information out there, but keep in mind we're dealing with subjectivity and personal preference. Instead of expecting to get it perfect the first time, consider taking a more "zen-like" approach, and enjoy the process of building and tweaking your system to your personal preferences.

Best wishes.

 

^ Agree with everything up there.

Clear out the rear deck and leave the holes with covers.
Don't put any rear coaxials in (especially in the coupe).

As for you list, you're going to need the scosche trim ring with the Pioneer + JDM combo, unless the shop can provide you with one.

Buy your own amplifier installation kit, unless the shop does full custom wiring and charges less than $100 for a 0 gauge install.

 

Ok, I'll leave out the rear sides and see how I like it, I hardly ever have anyone in the back seats away way.

Thanks

 

Thanks for mentioning about the trim ring, don't think I've seen that mentioned before.

What do you think about the PDX-F6 with the DLS components, would that go better together then the PDX-F4?

Thanks

 

Well, the trim ring is in my sticky'd shopping list.

As for the amps, I think there's better price/performance options than those, for the fronts, I'd go with soundstream reference for best sound quality, and then a good amp for the sub, like this: http://www.woofersetc.com/p-7713-v50...amplifier.aspx

 

Thanks again
