ahmi,
wow!!..good news!!. glad to hear ur wife is enjoying the car as much as u do..
ur car hifi now has a good foundation.. no need to upgrade here and there anymore.
juz need a better frontend(source unit) and a much better cables as it will be ur weakest link in ur system(bottleneck)..
Our guru of car hifi, Octave has audit ur car too. he advise the 1st RCA needs to be much better than bay C5 Hybrid. even with the mcIntosh deck in, the 1st RCA is still a persistant problem as it is not able to deliver the full potential of the HU(bottleneck). from the 1st RCA, you can slowly change the rest to a better ones in stages..
note: when you come down PJ, give me a call. will upgrade ur 1st RCA( on loan!) to a much better one. our guru, Octave says no point explaining, listen and experience the diff a premium cable and be the judge of urself
The alpine old school has no match for the superior mcIntosh MX4000 or MX5000 with external DAC. With full mods on it, its miles apart!!..
Its one of the best source unit I ever heard. personally I feel there's no HU can come close to it with the mods applied on it.
mods performed are also the same mods performed on the home hifi source unit and DAC. all parts are built for home hifi but we use it on the car audio.
you shall understand that it takes time for a system to fully burnt in and settled down, after 3-6months you will be 'rewarded' with a huge improvement over SQ. try to run 'pink noise' in ur system when ur back home as long as you can. after 100hrs, you'll love the results. after 300hrs you shall be even happier than before..lol. you dont need to have 'golden ear' to hear the noticeable improvement
* this is the reason why I dislike changing gears and it takes such a long time to run in, mostly due to passives and mods applied on it.
now u r are on the add on's games(more headcap pls!!) no more changing amp, speaker, sub and etc...
ur journey to car hifi is almost ended on this wira......
just sit back and enjoy the music..
