Audiopipe APSM-1300 output at 1.34ohms

[RSDXzec 10+ year member]

I'll be running 3 subs at 1.34ohm which could potentially take 1050Wrms all up, and I'm having a hard time deciding whether to go for the 1300 or 1500. I'll be running them underpowered anyway, I'd just like to get an idea of what I could expect to get at 1.34ohms with this amp. As I understand audiopipe does do rated power, unfortunately ratings aren't too helpful for people using 3 subs.

These also don't have fuse ratings, anyone got any idea as to how decent their efficiency is? Either way being class D I'm sure they'll be much more efficient than my A/B amp.

Cheers.

Just go with the bigger amp for more headroom

Bigger is better!

After imp rise, my 1.34 ohms are sitting at 1.9 ohms.

realisticly I most likely won't be going over 500watts, my cars electrical is my limiting factor, I just need an amp which can handle down to 1 ohm as my current amp can only handle 2 ohms. I'd just want an idea of what I could do if some day I changed vehicles or electrical etc.

Interesting, if that's true should my current amp be able to handle that if it's only able to handle down to 2ohms?

It doesn't matter, go with the bigger amp anyway if it's in your budget. It'll b the same current draw as long as you push out the same power, just give you more headroom

Yes if voltage is good 2 ohm amp should be able to handle that
