Time for a new install. Had an almost year long hiatus from doing anything related to audio and suddenly I had relapse and decided to install some "basic" stuff in my winter car. Well, that "basic" system kinda snowballed into a full 7ch active install - as usual I might add...
The car is a Mercedes-Benz E320T (V6 engine with 224hp), year 2000. The last Mercedes I had, the 280E from 1993 had an automatic transmission failure and I had to let it go. With over 170k miles I got it really cheap, I only payed like $600 for it. No issues except the damn rust in doors, fenders and about everywhere. I've fixed most of it now but it needs a paintjob which I hope I can pull off myself.
The system is kinda interesting because I got a lot of the stuff for free. All the amps, subs, cables and mids costed me nothing. The midranges are cheap drivers and the tweeters come from my last install.
The system consist of;
*HU & DSP; Pioneer P99RS
*Amp 1; MDS Classic 4ch amp (mid 90's). The MOSFETs on the amplifying stage were shot and so were a few smaller resistors. Replaced them with FETs from a spare board I had and replaced all the larger electrolytes while I was at it. The amp did 92Wrms@4ohms and 151Wrms@2ohms below 0,1% THD. At 12,7V
*Amp2; Kenwood KAC-7203. Was working when I got it. Connections are stuff was a bit oxidized so I refurbished it some. Looks as new now. A strong 2x180Wrms@4ohms and 2x255Wrms@2ohms below 0,1%THD. At 12,7V.
*Amp3; SPL Dynamics ICE-3500D. A real monster amp, was also working when I got it. However the amp has been mistreated, scratches all over and looks kinda ugly overall. Hid it behind the sub box so that doesn't annoy me. Never tested the output, but it claims to be 0,5ohm stable with 3200W output. At 4ohms which at I load the amp, it supposedly outputs around 700W, which is plenty. Has some kinda of clip prevention circuit which is kinda neat. It also got a PEQ control and both LPF and HPF filters.
Midwoofers; Audio System AS-165C. I believe they are made by Gladen. An awesome mid with crazy output. Haven't measured these yet but it's coming as soon as I get my new mic and preamp. They are mounted in stock locations with a baffle modifier.
Midranges; Vifa TC9. Amazing cheap 3,5" driver. Performs like a high-end driver. Fits perfectly into stock locations on the dash corners. I have tested these previously here: Vifa TC9 - 3" Midrange/Widebander REVIEW/Measurements
Tweeters; Gladen SQX. Used in my previous Mercedes. A low distortion, great performing driver. Fits behind stock sail panels. Previously tested here: Gladen SQX System
Subs; Taken from a Logitech Z-5500 system, well actually two of them. The drivers are produced by Tang-Band and is very similar to the WT-644F. Very clean sounding drivers, suitable for vented alignments.
Cables; OFC 4ga for the sub amp and OFC 8ga for the other two amps. Battery is behind the rear seat so no lengthy cable runs. Decent looking psuedo balanced RCAs and ordinary 12ga OFC speaker cables.
All drivers are mounted in stock location. So this is basically a somewhat steathy stock looking setup, except the sub enclosure that is.
Goal is, like my other builds; SQ oriented systems that can get loud with low perceived distortion. The system is almost completed, took me less than 3 days to pull this install off. That's probably the quickest build in any of my cars. I will have to go back and fix a few things though, I kinda rushed the dampening in the left door and will have to remove the door panel again to fix the small but annoying rattling, probably from the vacuum hose to the central lock system. I want to measure the midwoofer anyway so I'll do the dampening and pull the driver at the same time. I also got a lot of tuning to do, it's a pretty solid tune as of now but it can get better - I hope.
I will also pull the left midrange driver and experiment with some acoustic wool behind the driver. I also need to investigate where two high Q peaks in the 4-5kHz area are coming from, they are clearly audible and annoying on some songs. So far I've concluded that it's not the speakers themselves causing it. I will hopefully shoot a few videos later on too.
My memory card containing most of the pictures somehow found its way into my uncles car. So I'm currently waiting for him to return it to me lol. Here's what I got so far on my phone;
