What size is your enclosure and tuning?

What size is your enclosure and tuning?

It’s the dual L7S 12’s on Amazon for 639 prefab box

It looks like 1500rms total which is 750rms each sub. Description says it’s wired to 2 ohm. If you changed the wiring and made it 8 ohm that’d make a difference.
I think the goal is to be between 20% over or under on wattage supplied by the amp.
If that jd puts out 1000 at 2 ohm you’re really 33% under par at 2 ohm.
May want to double check wiring and double check gain setting.

I set the gains with an oscilloscope the wiring seems fine I think it’s underpowered don’t get me wrong it hits still but I thought it would be harder I just received a new amp the kicker cxa 1800 that should work.

I have a problem with my remote when I turn the key off from the car the amp will stay on and sometimes go off. I gotta figure that out.

There should be a noticeable difference between those two amps. You might want to turn that new amp down a little, but maybe not. Let us know how the new amp works out for ya.

Prefab box is probably not doing you any favors..

Yeah I’ll let u know I know 1800 is too much can those subs handle 900 a piece though?

It will be fine.. I like to run double RMS of my subs.

It hits hard in my brothers car but I notice in a suv you need more power

wow double isn’t that too much

Let me ask do u think I need a capacitor or an alternator with that thing amp or am I good stock? My alternator is 150 amps.

If you know what it sounds like when subs are reaching there limits it is not a problem.

Nah, the gain controls the power. The speakers may take a little more than rated and still perform well. Double it’s what’s known as overhead.

What do you have for a battery?

Ok

4ga wire will need to be replaced w 0ga.
Capacitor is not my first choice.

I have a Walmart battery lol I’m thinking about getting an agm

A solid upgrade is higher performance battery and ho alternator.

A good battery is important, Get the highest amp battery you can fit.
