I have 4 12"s will i have to install a second battery for it to push like i expect it too?

Always upgrade the big three first bigger wire,alternator, and battery before adding anything like one guy said capacitors are garbage they mistakenly make you think they do what you want them to do but they do not at all.

Is or will it handle 0.5 half ohm running daily?

Highly not recommended. Can it? Yes For how long?! Heat and component build will decide that

i have 2 evl-15 d2 with 3 yellow top batteries and 2 alternators set up. which amp would i need to push my 15's seeing that i have plenty of power???

I’m selling one of these amps. Brand new. On eBay
