I certainly will as I have half of the electronics already to make it sound fantastic. As I said earlier, though, I intend to live with the factory Nav system until it gets me lost a few times because it actually sounds very good. Also, the nav instructions and radio info are displayed where the dials show - it's a good setup.
Speakers wise, I would go with focal again I think. I have always loved Blaupunkt gear, just never tried their speakers/amps in my cars, yet.
That's cool that it displays where the dials show. Reckon speaker wise whatever sounds good to your ears is the one to go for, budget allowing of course:)
So far liking the Blaupunkt amp even though it's a bit of an older amp and was second hand.
You have a crossover built into your head unit? - if you left it "flat" and used the crossover in the amp, the amp would reject noise below the crossover frequency, reducing hum.
Apart from increasing the power handling of the front speakers, increasing the srossover frequency above 100Hz can help reduce intermodulation distortion, the typical bass note or kick drum will have elements above 100Hz, this means bass notes will be spread between the sub and the front speakers, which may cause phase distortion, raising the frequency so that the sub handles kick drums/ bass notes should give you tighter bass, and overall sound, phase alignment would help, too, of course, this is all theoretical and its what sounds good to your ears/ and to your taste
Not sure if there is a cross over in the Pioneer AVH 2500BT for the front speakers. Still getting used to all the settings for it. Spent 1/2hr today playing different types of music and playing around with the settings off the amp and the head unit. There is still a bit of hum but no distortion coming from the front speakers any more. There was a tiny bit before especially on a track like Daft Punk - Around the World, coming from the front speakers. At the moment, I sound the music is to my liking but I will keep re-adjusting the parameters till I am perfectly happy. I think I might have done what you mentioned by total fluke without knowing the theory behind it lol.
It is most important to separate the power cables from the rca cables. This is because any hum will be multiplied through the amplifier. Speaker cables will not have this problem. Turning down level on the amplifier is good, as is having solid earthing on both head unit and amplifier.
Pioneer head units are known for blowing their earth fuses - located inside the head unit. This can happen if you have bad earthing connection on the amplifier and large current will flow through the rca cables - blowing this fuse. This will result in alternator noise in the speakers.
This link is showing a cheap fix:
You can try if this is your problem - by just only for a moment connect a ground cable to the shielding - to check if the noise disappears.
Edit: Trying a good quality, well shielded rca signal cable could be worth it.
At the moment, the RCA cable from the head unit to the amp in the boot is running fairly close to the power cable for the amp. I reckon that this might be the cause for the hum. I tried relocating the speaker wire during the weekend but no luck. At present, the power cable, speaker cable for the left front speaker, remote wire for the amp and rca cable for the front speakers are all running on the left side of the car, near the door sills.
Any ideas on a good placement to relocate the power cable or RCA cable without too much hassle. Found out that I couldn't find a spot to pass the RCA cable from the head unit, onto the right hand side of the car and all the way back to the amp in the boot.
I was also thinking of getting a set of Vibe Black Air 6 component speakers for the front of the car.At the moment, I only have one amp (Blaupunkt GTA 470) that is powering the front Vibe 6 Slick speakers and the 10 inch sub. If I were to get the component speakers, will I need 2 channels ''Front and Rear inputs'' to power the woofers and the tweeters separately or can I just use the ''Front input'' that will then feed into the cross over which then wires to the woofer and tweeters with that input set to ''Flat'' ? I hope I am making myself clear and my apologies for being an ICE noob. Found a 2nd hand set of these speakers and very tempted to get them and move the Vibe 6 Slick to the back of the car, just powered by the factory wiring present. Reckon that might give the sound stage a bit more dimension and quality.
