OK, here it goes again....question about alternators.

OK, here it goes again....question about alternators.

I have found a place that will build a custom alternator for ME!!!! They said they could also install a aftermarket sensor that will turn the alternator on fully at a lower RPM range. Both those components were quoted to me for 680 which included all parts, labor, and a full 1 year parts and labor warranty. WHAT DO YOU GUYS THINK?

I wanna do this mid january, would guys guys pay that or do yo uknow someone else. By the way I went with the ebay one and they sucked ass!!!!

thats a much better post...

Your going to pay $700 for an alternator?

I will see if they would do a group buy to......

yes 700 dollars for my battery not to die well worht it

why not jsut get a dynacell, they don't die realy, and ar much cheaper...

ok you guys dont dont know what i am pushing. I am pushing a 13w7 subwoofer powered by a 1000/1 jl amp. I WILL be pushing another 1000/1 amp for my sub, as well as a 4/450 jl amp, 15 inch, 750 watt inverter, 4 9inch tv's.....and many more cathodes, neons, and strobes to boot.

I have have a yellow top and a blue top marine battery and my system kills em when at idle most of the time and if I am not careful

I have a better idea TJ, why dont you just hand me the $700 so I can buy something that would be useful.

The only thing that I don't understand is the sensor to fully turn on the alternator at lower RPMs. Turn on what? Switch to a different alternator? Some type of geared transmission inside?

That being said - a one off alternator for $700 is about right - not cheap to make one that puts out the juice at all RPM ranges. Costwise - you can either get a heavier alternator or gang-up a bunch of batteries in parallel or a combination of both.

Might be cheaper to get a slightly beefed up alternator coupled with some sealed SVR brand Car Audio batteries or similar (dry cell, deep cycle, fast recharge, high current) setup in parallel. Cost should come under what was quoted for your one-off alternator and you get easier parts availability (ie. run to a store and buy another unit) if that fancy custom alternator takes a $hit on you.

like another set of rims?????????

idk i would spend the 700.... thats alot of power ur pushing

just becareful otherwise ur car may just catch on fire and it won't be a happy sight. been ther done that.

Forgive my electrical stupidiness but wouldnt a second battery be the cheaper route?

no it isnt stupid, you still have to charge that second battery though.

you can charge 2 batteries off of a stock alternator... hell you can charge a bunch, just takes time...

but you dont have time when your given 30 seconds of bass time.

get a cupple of deepcycles jels and call it good... and maby turn of some lights when your hittin the bass... oh and get a cap..

had a cap, and all it did was drained my battery

I read somewhere where people used marine switches (boats have two batteries) and only switched it to both batteries when they had their sound system running. Research it, Im sure you'll find out something.

italiancorolla, i think what you need is a high-output alternator coz our stock alternator is only 80 amps. You need a higher one like 150-200 amps. But you need to calculate first how much load your putting into your car, so that you would know the exact amperage you need for your alternator and give it a little extra for safety.

I also plan to get a high-output alternator but too expensive to have it custom-made. I got a quote for $1800 canadian.

wow dude, I was quoted 530 out the door, they would need my car for a day and even make brackets to bolt to my stock location so that if I went back to stock I could.

I have a marine battery switch already
