Car Forum / Driving, Maintenance, Tuning / Car Audio / April 2004Older Alpine Vs. Newer Alpine HU's
Hi all: I have two systems setup almost the same way in an Acura Integra and a Toyota 4runner. Both have Boston Pros for the front, and cheap Bostons for rear fill. Each has a Boston Pro 12" sub in a sealed enclosure and both are driven by an Xtant 603X each. There are two main differences between the systems. One has an older Alpine 7840 (Integra) HU and the other has a newer Alpine 9815 (4runner) HU. Taking into consideration the size difference between the cars it seems that the older Alpine performs a lot better than the newer one quality wise. The highs are crisper and the bass has more definition. The 9815 sounds a bit dull. I have even tried to change the settings with that file you configure and download from the Alpine site. Has anyone experienced this? Why could be the reason for the difference? I am asking this because I am getting ready to buy a new car and I am really in love with the 7998. But I rather have good sound quality instead of good looks. I am going to keep everything from my old system except for the HU, which I was thinking to exchange the 7840 for the newer 7998. The car that I am selling is the Acura and I am going to put the system on a G35. I wanted to get some thoughts from people that have experience with older and newer Apine units.

I am pretty sure there is a significant difference in favor of the older unit. > > Hi all: > > I have two systems setup almost the same way in an Acura Integra and a [quoted text clipped - 14 lines] > You can't cross-compare between cars.

As I said, it's literally impossible to make meaningful comparisons of ANYTHING between cars, unless they're identical cars and identical installations. For example, different speakers in the same car will usually sound more alike than the same speakers in different cars. I have now tested both units in the same car, just swapped them. Same everything else. How do you know it is not true?

I notice the difference, my > be the newer one in not performing 100% I know it is not true between working units because there is no difference in their electrical signals. This can easily be tested with distortion analyzers and spectrum analyzers. So if there's no difference in electrical signal, where would you suspect the difference comes from?

Please > advise. All I can offer is that I've been running a 7998 for about 9 months and the SQ is excellent. But it's the first Alpine HU I've owned so no comparison from me. I was initially hesitant about the Fantom Face mechanism eventually wearing out, but so far so good. |
