NO! They need to be the same. You will also need to upgrade the charging lead.

You need a battery or two if you like to float/ swim for extended times. The battery needs to output its rated output until its toast or you will kill amps.

so this thread has me a bit concerned now.

i'm doing another stereo upgrade and now i'm concerned about my alternator and the charging lead. how do I tell the output of the alternator on my 2003 X-2's MCX? I guess I always assumed it was 90amps.

i'm replacing one of my amps and adding a new one with a pair of tower speakers.

it will be 1000W RMS on one amp (200x2@4ohms and 600x1@4ohms) and ~400W RMS (200x2@2ohms) on the 2nd. i'll never see that kind of output though. the smaller amp is a class AB and the larger one is a Class G/H amp with regulated power supplies and fans.

jim, you're going to tell me I need to change my charging lead aren't you?

i'm using 2 optima blue top d34M's with a surepower 1314 battery seperator

I would. Adding current draw will increase the charging current, and the OEM lead is only sized for what they anticipate.

shucks i knew you were going to say that :p

gosh darn it

jim, is it easy enough to confirm to the alternator's rated output by looking at it? anybody know if there was a certain standard size for mcx for my model year?

one thing that's odd is the little stock fuse/circuit breaker right next to the starting battery is only 50 amps.

My 04 was a 70 amp and I think in 05 or 06 they went to 90. Bet yours is 70, look in your manual mine was listed there.

Call MC. I was under the impression they had upped the capacity to 90A or 95A. The 50A breaker is for the accessory harness, IIRC.

ha ha sorry tx.x-30 fan, no not on ignore and you're right. pulled out my owner's manual and the specs state it's 70 amp output at 2000 rpms....

i tried to see if i could read the red fat wire coming off of it, but it doesn't list the gauge, at least the part that's exposed it looks pretty big though, but without seeing the actual wire, who knows. it could just be really insulated.

so now what? 70 amps? am i in trouble here?
