Do I need a bigger alternator?

[mwoehr 1]

I have a 2006 Toyota Corolla Type S and I was wondering if any of you have the same car and have a system in it or have seen a system in a Corolla Type S? I need some ideas on setups. Right now I have a Batcap 800 in the trunk along with Dynamat in the trunk and under and on top of the rear deck, a JBL GTO 1200.1 II amp powering 1 Icon 15 in 3.5 cubes ported tuned to 34hz. I already have a 70 amp alternator and have just a little bit of dimming. Do I need a bigger alternator or would a Stinger SP1000 battery and solenoid be enough or should I get a both the alternator and bigger battery/solenoid? A friend of mine said that if I get a bigger alternator that I should go any bigger than 140 - 150 amps so that I don't fry my cars harness. Does that sound right to you? I just want to upgrade, not cause hundreds worth of damage to my car!

your buddy is a tool if you want to upgrade your alt get the biggest one you can you have to upgrade the wires called the "Big 3" anyways on an after market alt Im pretty confident in saying that even f you didnt upgrade those wires you would be fine tho it would waste quite a bit of power from the alt because it wouldnt transfer as well as it would with upgraded wires

try the big3 first and see if that helps with the dimming.

Your buddy is pretty dumb, but you don't need a very big alt for what you have. An alt upgrade without a battery upgrade is kinda pointless so I would add the extra battery first. If you're still having problems, then think about an alt, but the battery makes the biggest difference on transient draw (which your audio system is).

hey have you check this, it my help

now before you upgrade your alt, find what is the highest volt that your system suport, specially your ECU, 'cause as far as I know Toyota's does not handle more than 15.6 or 16, so I strongly recommend that you do that first.

good luck!!

I'm kind of in the same situation, running into problems no one can help me with, it seems. No one makes h/o for imports w/out doing major mods and you have to have pullies and brackets custom made at a very steep price. Even if you can make the parts, getting them on the motor is a dangerous proposition at best. It's gonna cost you money anyway so here's what you're better off doing:

You can get a h/o alt with some batteries ($1200.00 easy and around 200 lbs at least) OR, what I'm thinking about doing, getting a BatCap 8400 (70 lbs) off of Ebay, getting the charger that goes with it(do NOT hook one of these up to a regular battery charger!) and hook it up to the system completely seperate from the car, and it will bang for days before you have to charge it again.

I'm thinking of just doing the big 3 and getting a solenoid and Stinger SP1500D - SP2150. Not sure what size battery I want yet.

All I had in my last car was a solenoid and SP1000 and I didn't even do the big 3 and there was no dimming and I was str8. Of course there were times I didn't feel like listening to music so my battery stayed charged good.

look into odyssey pc1200's-pc2150's you might get them for less and the warranty is 2 years longer..also think you would find them to be very simular
