Hey guys a got quick one for ya. today on the way home from work i was runnings some sine waves for test the 35hz to 50hz on the ole 2000spl and it just stoped hitting upon further inspection i saw i had blown the fused to both of my amps powering the sub. i checked for loose wires nothing checked all connections seemed to be tight i pulled the sub out of the box and saw a little discoleration on the negative termenal of the right vc. looks like it had been arcing a bit if thats possible i dont know. could this be the reason i blew both fuses for both amps? there not connected to each other in anyway so im not sure how both blew at the same time?

Well if there is discoloration you may be arcing. I would cover the area with electric tape to help eliminate it.

As for the amps...

Well you may have strained the system to hard. The Ohms may have just dipped to low...

ok got ya hopefully the new alternator will fix that i tested the ohms the other day and they were right at 3.93 but that was under no load. thanks

Well to test resistance it cant be under any load. The item needs to be pulled out of circuit, otherwise your measuring the full circuits resistance.

I assume you have all the proper cables upgraded under the hood also? Likewise your ground point in the trunk is vital if your running high power...

this was all professonaly installed im upgreading my alternator today just got it from execessive and im doing the big 3 other than that im running 1/0 so that should be plenty for now. i check the ground and it looked good. Any thing else?

I tried looking up a 2000SPL amp and cant seem to find it on Pioneers site...

Hopefully that will do the trick. Bear in mind its been tested and noted that the chassis ground is only capable up to around 125-130 amps... Im sure it can vary from car-car.

If you have a truck with an actual *frame* then ground to it.

Otherwise it might be beneficial to run another lead from the - to the rear of the vehicle...
