About the yellow thing on the pcb-s is not going off easly but with all the pcb markings so i let it be Cry i prefer to know the values of the parts more than a crystal clear pcb in this case,as no schematics or even specs available anywhere Smile]]> Sat, 20 Jun 2026 21:56:27 +0000 https://forum.speakerplans.com/amplifiers-rescue-gods_topic107113_post1082832.html#1082832 <![CDATA[Amp Forum : Amplifiers Rescue Gods]]> https://forum.speakerplans.com/amplifiers-rescue-gods_topic107113_post1082831.html#1082831 Author: EmPro

Yeah.....these Hitachi are quite crazy output devices....this amp is basically running them for +40 years at 170vcc..... 10+ more volts than maximum rating,and still going strong and all the same lot so never blew up! I test them and all are like never been used....quite amazing!!!]]> Sat, 20 Jun 2026 21:45:24 +0000 https://forum.speakerplans.com/amplifiers-rescue-gods_topic107113_post1082830.html#1082830 <![CDATA[Amp Forum : Amplifiers Rescue Gods]]> https://forum.speakerplans.com/amplifiers-rescue-gods_topic107113_post1082829.html#1082829 Author: EmPro

Yeah.....not quite enough space for other position of the transformers....i recapped it today all,just 22 capacitors...some of them completely dead!! 47uf shows like 36-34pf.....some of them 45% voltage loss and 9-10R esr.....sounds awesome to be honest and have a lot of power in 4R! Quite impressive for 8 Hitachi!!]]> Sat, 20 Jun 2026 21:41:23 +0000 https://forum.speakerplans.com/amplifiers-rescue-gods_topic107113_post1082829.html#1082829 <![CDATA[12v Powered Systems : 12v Sound System the Basics]]> https://forum.speakerplans.com/12v-sound-system-the-basics_topic109603_post1082828.html#1082828 Author: KDW32

Maybe a class  d amp by pioneer would be better and it will have less drain on your battery

Build a B&C sub 18 and put a suitable driver in it.
The plan is available online Thumbs Up

hey,
i would suggest to get a LiFePo instead of using car batteries, they pack more power into the same weight, and feature built in short- and over discharge-protection. the battery management could also have bluetooth to check on discharge rate and capacity left via app.

car amps are a good choice for starters, and you might not need extra equipment like a cross-over or dsp. if you want more control than what a typical car amp offers, there are some with dsp built in. an advanced solution is a dsp connected to class d amp boards running on 24…60v for even more power.

yes, you can run regular equipment via inverter (to produce AC) but that is a lot of extra weight and cost, unless you already have all that other stuff.

best, J
