Boss 2500GT mono block car amp white smoke after 5 mins

White Smoke --usually a sign of a failed head gasket
or other issue, allowing coolant into the cylinder & a major
repair

White Smoke only on start up after sitting (Not Lasting 5 Min)
is raw fuel (gasoline) from leaking injectors, leaking fuel into
the cylinders

Injectors can fail,wear,leak or be dirty & NO you can not clean them

Forget the Genie in a Bottle The injectors have to come out & be
mailed away for Ultra-Sonic Cleaning

That condition - the raw fuel- will over heat your exhaust converter
& ruin it as well as many other problems-lack of fuel control the
main one.

white smoke is a blown head gasket [white smoke burning anitfreeze]

The motor has a sort circuit, probably you will have to replace it

Sorry but white smoke is a sign of water getting into 1 or more cylinders.I would pull the oil dipstick and see if it looks like a creamy color.If it does then you may have a blown head gasket or a crack in the engine block somewhere.

if the wiring to the sub is correct, then you have something wrong with the amp itself... something is power surging to the subs which is causing them to blow

check your positive supplies, are they properly installed? and your ground is is properly grounded?

White smoke is usually from water and water will make the car splutter. Did you get water in your tank at some time. If you have water in your fuel, you will have to drain the tank and refill with good fuel. The engine will run fine once it is hot but if a lot of water goes into a hot cylinder it can cause a lot of damage.

Check the photo eye to make sure it is clean,clean it with soap,and water,and add a additive to the fuel for gelling.

well how manny amps can the sub hold? any amp will work you can bridge it to doulbe the power but i would say a 200 wat amp would do you good
