i got a 2003 g35 sedan with the bose package, this is what i can't decide


1) stock bose HU, stock amp with infinity 60.7cs, infinity 62.7i,
mtx amp for the 2 10" infinity's
(the cheapest,easiest way)
--------------------------------------------------------------------------
2) stock HU, 4-channel helix amp, infinity 60.7cs, infinity 62.7i,
mtx amp for the 2 10" infinity's
(cheapest but harder and more time consuming)
--------------------------------------------------------------------------
3) alpine avi-d300, 4-channel helix amp, infinity 60.7cs, infinity 62.7i,
mtx amp for the 2 10" infinity's,PAC SWI-PS steering control, PAC TR-7 Alpine Video Bypass, double din kit
(the most money,time but the way i'd like it the most)
--------------------------------------------------------------------------
these are the items i have at home: alpine iva-d300,mtx sub amp,helix
4-channel speaker amp, 2 10" infinity's

i kinda want to use the stuff that i have at home but don't really want to buy the double din for $300+ i'm gonna buy the infinity's for the doors either way

i'm leaning towards the second option but what would i use to convert the speaker wire to rca's since it uses differential-balanced signal,also the stock HU doesn't have the sub-output so i'd have to steal the signal from the door speakers,or buy this double din kit

the only thing is that the buttons look cheap maybe they can be swapped with the stock ones?
let me know what you think
thanks matt

 

I would just stick with the factory double din kit. Sure it's a few bucks more, but becuase this is such a high visibilty item (you're gonna be looking at it every day) you will want something that you know for sure matches and that will fit perfect.

I say skip the rear speakers and use that money on better front components or sound deadening material. The rears are not really necessary, if you do want to run them just use the stock as they are good enough for fill. Also you can save a few bucks and get a 2ch instead of 4ch amp. The rears really don't need a separate amp, as the deck power is adequate for use as rear fill.

 

the infinity's for the rear aren't so much money under $100 on ebay and the amp i already have at home from previous car but i think you're right about the double din, i'll probably get the infinity's for the doors and hook the 4-channel to them,then down the road just get the good double din and put the iva-d300
