[Box design.....HELP M3 8's o. 1.2K]

Just finished installing a DC 1.2K running (2) M3 8's.....threw the subs in a quick sealed .75 cube each enclosure....holy hell,  it sounded BAD....I KNOW I SCREWED UP using a sealed box, was in a hurry to get them running,  so here I am needing enclosure design help.  It's in a 2015 Honda Accord EX-L sedan. I'm very handy,  can make me own enclosures, have done so many times. I'm an old school audio junkie from way back,  just getting back in,  used to use a ton of the old school,  American made RF power equipment back in the day,  now switched to DC.....again please help......i can answer any questions to help

[DC 1.2K amp question]

Quick question...

On the DC audio 1.2K amplifier,  is the RCA output "full range" or controlled by the included crossover?

[Newbie question.....sorry]

Perfect.....thank you

[Newbie question.....sorry]

Sorry for this very remedial question, bear with me as I try to get up to speed.

What is the "Big 3" that everyone keeps referring to?

Thanks in advance.....

Deep tight bass, with a good SPL...

[M38 or L6 18"]

In an 08 4runner.....is running (4) M38's a better idea than a single L6 18"

If I went the M38 route, would the 3.5K amp be adequate?

Thanks in advance for any help
