Question

ok so im running a single 2 ohm dvc Alpine Type R to a single TMA(JL Audio) T360.2 2 Channel Amp 110 watts x 2 at 4 ohms, 180 x 2 at 2 ohms or 360 watts x 1 at 4 ohms bridged ....i was running it to a Class D Alpine MRD-M1005 700 watts x 1 at 4 ohms 1000 watts x 1 at 2 ohms however i stopped becuause i smelt the voice coils and figured the amp was overpowering the sub....now when i wire the 2 ohm sub to a four ohm load and bridge it to the amplifier (TMA) the amp eventually gets very hot like within 15 minutes and will eventually shut off also the sub gets hot so i unbridge it and get better heat results but i lose power...everything is wired correctly im pretty sure and my power and ground cables are 4 awg and tight...the sub is in a large box sealed with plexi glass and is vented only at the bottom.......if i were to get another type r could i then run them safely to the 1000 watt amp and if so would i see a significant gain in power from two subs than one?would a 360 watt amp push 2

by the way the type r is 500 watts rms 1500 max its a 12"

WOW MEONTHKIOLLA YOUR CRACKED THE CASE YOURE A GENIUS LOL

Answer 1

honestly you should be fine with the alpine amp at 4 ohms. just make sure you check your gains. and if you were to run 2 subs off the alpine amp at 2 ohms, that would be fine too. you may not notice a whole lot of loudness but there should be more SQ.

Answer 2

I guess the first question that occurs to me is: are you sure the subwoofer wasn't damaged when you smelled the smoke? If you have damage to one voice coil, you may have a dead short that's causing your amplifier's overheating.

If you have an multimeter with an ohm function, I'd test the resistance of both voice coils and make sure they're not different values. It's possible to have one shorted voice coil and one good coil, resulting in a 2-ohm load at the amp when the sub is wired in series.

Answer 3

That's a scary question, I never wish to face such a thing in my exam paper !
