Titanium 1200.1
Hi guys,i am new here...i have one quick question,is it safe to run Ti1200.1 with 1.5 ohm load for daily driver?....thanks a lot and looking forward to get answer for my problem.

i should say this then, i wouldnt recommend it.
the amp will get hot and the i believe it will hit high current mode and taper off the output power.
could be wrong, but i know if i run my 1000,2 four ohms it seems to
sound better and also louder then 2 ohms.
might be me.
i did run a elite 12d on my 1000.2 with both voice coils parallel and
it got very hot....
good luck.

You may have subs in your car........but my doors sound better!
I don't want to pick a argument here either, but what the hell heres my techno 2 cents worth also.
The Ti 1200.1 is a "INTERNALLY " Bridged amplifier. In fact it looks a heck of a lot like a Ti1000.2 except mono'ed inside.
Same number of outputs, and the same type also.
And at 1.5 ohms theoretical load, your placing a 3/4 ohm load on each internal channel.
It will be "HOT LIKE HELL", and depending on how heavy you lead hand is on the volume control, you might be headed for the repair station very soon.
I just checked the pdf for that amp and it says minmum load 1 ohm, but only rates the amp at 4 and 2 ohms.
I believe after it cuts off on you from overtemp a few times your probably gonna want to sell it to me for cheap

It all depends on you the operator, and your install. Are the subs inside the cab of the vehicle ? or are you listening to trunk bass?
I ask because some of my best customers listen to trunk bass. They seem to blow amps alot also

I think you guys are totally overreacting... 1.5 ohms nominal impedance is a negligible difference compared to 2 ohms. The Ti1200.1 is designed for 2 ohm bridged loads, not 4 like the 1000.2 is set up for, so it's not like we're talking overloading this amp by a large amount here.
Remember... this is nominal impedance, which will vary depending on frequency anyways, and we're only talking a 0.25 ohm drop per channel, at most! If the amp couldn't handle that small of an impedance drop, it would be worthless, as it could never handle the impedance shift of another woofer either.
I guarantee you that the Ti1200.1 can play 1.5 ohms all day long without thermal issues. I've done it, and hundreds of others have done it, by hooking the amp up to their Elite 12D's.

I ran a pair of ti10's dvc at 1 ohm, and it takes it for about an hour of pounding and it goes into thermal protection.
But I wouldn't doubt it can last a lot longer with casual listing
How is it that I can thermal my 800.1 in about 10minutes at 2ohm load. Granted that thats pushing it hard and subs are hitting excursion limits.

Guys..i just installed a pair of JL Audio 10w6AE with Ti1200.1 run those subs at 1.5 ohm mono..i cranked the volume up for 30 minutes without problem...there was no sign the amp would go in thermal protection at all cause i checked the amp every 10 minutes and just little bit warm...i guess it's safe...what a great amp!!..thanks guys for everything!!!..i will keep you guys updated.

Yes please do, I have found some speakers present more difficult loads to amplifiers. I think you found a good combination. And I really do hope it serves you well.

Well I know it has been said many times in this post but I just wanted to put my two cents in.
If you guys remember Tad and Mel, I had multiply conversations with them while they were at PG and I was trying to purchase a TI12d Elite.
However, the amps designed by PG to power the TI12d Elite to full excursion were TI1200.1, TI1000.2, and T1200.1. These three amps were designed to handle the 1.5Ohm Nominal load all day.
If you wanted to run two smaller amps one per coil you could run two T600.1 or two TI800.1 to power the beast.
So again like you found out for yourself the TI1200.1 will not have a problem driving the 1.5Ohm Nominal load of your Four JL subs.
We always have to remember it is not always the impedance that you are driving you have to worry about. It is how much actual power you are going to use.
Even though the impedance of the sub stays the same and you have so much power you can make at that impedance. You will only reach that power if you have saturated the front end.
I have driven amps to there limits. I still have my ZPA0.5 that I drove at 1/2 ohm mono for a full year until i changed my stereo setup and bought a second ZPA0.5.
Hope this helps the confusion.
