Ti 475 overload ?

twisted · Post by **twisted** » Wed Dec 13, 2006 7:54 pm

i have a question about my Ti475.
when being driven hard after aboout 1 1/2 minutes it goes into overload.
i have a panasonic HU, Ti475 for mids with MBQuart reference components in the front doors and MBQuarts reference coax's in the rear doors.input sens is just under half way with no bass boost at all.
i gave 4 guage running from the battery to the fuse dist block in the back and 6" of 8 ga to the amp.

do i just need to step up my power wire to 0 ga to the back and 4ga to the amp? or is there a problem with the amp?

it just started doing this this afternoon.

Have you checked your cooling fan ?? I would tend to think it might be time for a new one

1 1/2 minurtes hard is a lot of heat without a cooling fan spinning, just a thought

it seems to be working...i could feel air moving but not a whole lot of it though

You really need to up the gauge size wire also. That amp requires a minimum of 4 gauge (according to the manual).

that was kinda one of my thoughts but i dont have amanual for it.
but i was thinkin the 8 ga might be a little small.

BTW nice amp, I hope it works out for you.

Yeah wire could cause some strain issues on the amps part, good catch guys.
Buy my experiance with all the Zpa,Ti,ZX amps with fans. well they wear out the bearings on the fan and the next thing is a SLOW fan, and a slow fan is a hot issue with these amps.

Hope it all works out for you buddy

Which light is actually coming on when it shuts off? THL or OVL?

If it is OVL check your speaker load and terminal voltage, you may have a failing battery, weakened connection in your power cable, or a failing sub(s).

the THL red light inside the amp is coming on.
its cuts the sound to all of my door speakers and after i turn it down for a sec it comes back on. it acts like the amp is over heating kinda but it doesnt just shut off it kinda fades out.

and i checked the fan after it came back on i turned it up again to about 3/4 volume (were it shut down last time) and looked at the fan and it was spinning but doenst push alot of air.
what is the best fan for replacment/upgrade for these amps?

No probs- anytime, I don't mind helping a brother out.

With the THL light coming on it is definitely heat related.

Check your speaker loads make certain they are all within reason, you need a meter.

Hit the case with compressed air the heat trees on the FET's can be buggered up along with the fan, this can limit air flow.

If all else fails pull the fan and visit your local computer shop and pick up a matching replacement fan.

Yeah, Fan

The $4.00 fix... works for me. I even replace those on my repairs just for GP's.

yeah i had the same issue with my ti1000.2

so i opened it up and there was nothing but dust bunnies in all the
fet legs..cleaned it up and works like a charm.

now if i could get a new ti cover preferably the aluminum one
i would be very happpppy

so i swapped it out for my alpine that was in my truck and it works perfect now!!!!!!!

but now i want somthin with a little more volume.

You should still consider upgrading the wire so you don't put too much strain on the amp.
