After the successful modification made to the gearbox cooling system https://jabawoki.com/2016/01/27/alfa-159-gearbox-cooler-modification/ I found that, while the cooling was perfect while the car was moving over 30mph, there was an issue at lower speed. Continue reading “Gearbox Cooler Mod Tweak”
For the last year or so, since I have been pushing the power limits of the Q-Tronic Gearbox, I have had an issue that has been getting progressively worse, as the power increased. Continue reading “Alfa 159 Gearbox Cooler Modification”
Daily Power is a work in progress but boost is at 3500mbar and fuel is flowing at 130mm3 so it should be good for a solid 800NM+ as a daily driver 🙂 #noSmokenoPoke Continue reading “Alfa 159 Ti”
The final stage was putting all the wiring in place. I opted for 4 gauge cable from the battery up front and a 4 gauge earth in the rear, both connected back to brass 4 way distribution blocks so I could pull 8 gauge runs to amps and the line converter. This also left me the easy upgrade route for adding additional amps to run upgraded mids & tweeters in the cabin, but that’s another project!!

Once the car was pepped and ready it was onto the enclosure build. This was a combination of trial and error mixed with some loose calculations and estimations around box size. I had worked out utilising box design software that for my sub, a 0.6 cuft sealed enclosure was going to give me good responsive SQ and enough power. This also suited my limited boot incursion requirements so was ideal. Continue reading “159 Custom Bass Project – Stage 4 Enclosure Build”
Once the planning was complete and I had the Amp prepared for some serious load, it was over to the car for a complete strip of the boot and sound proofing. The approach taken was to utilise a number of different sound proofing materials once I stripped the car back to the shell. Continue reading “159 Custom Bass Project – Stage 3 Sound Proofing”
I already had the amplifier and sub from a prior install, and in that install I had discovered a problem with the pairing. The sub is an Infinity Kapa perfect 12 VQ rated at 400w RMS and the amplifier is an Alpine MRV-420 rated at 350W RMS. Driving the sub at high voltage, with line levels in excess of 4v and the gains maxed out means that the amp is producing closer to 450W RMS and the sub, which is well regarded as being able to handle much higher loads than 400W RMS, just laps it up, but had one small issue that needed sorting. It would overheat during extended sessions of Drum and Bass at full power! To sort this issue, I stripped the amp back to bare metal, rebuilt it using high grade CPU heat sink paste and added a temperature controlled cooling system utilising 6 x 40mm fans in a push/pull config. Needless to say, it can run at full power and then some, all day long now ! Continue reading “159 Custom Bass Project – Stage 2 Amp Mods”
