they're good amps, power hungry though.

Search on ebay, they're always "cheap" compared to other 4k amps

^^^^^ That's because their efficiency is so terrible that nobody without a ridiculous charging system can get 4kw from them

Well I have the charging system but I'm adding 2more L7s. So Im hoping that adding two more yellow tops which will give me 6 i should be ok.

" Well I have the charging system "

I seriously doubt that. Do you really have 400+ amps of alternator? That's what those amps have been known to draw.



And batteries do not give you more power. Power is supplied by the alternator.

I have a 300ho alt now. The purpose is for burps and not looking to invest on a bigger alt or altenators.

well M.S you're right lol! you need around 500A to get 4200w rms at 12V, but it would be a great amp if you run it at 2 ohms etc. Also depends the amount of batteries.

IMo search the market, if the price is right then grab it
