System doesnt sound as good as it should

What is your remote daisy chained to? What is your voltage at the amp, remote wire? How is it grounded?

How did you set your gain?

turned it up to 19 which is alittle before my stock speakers start to distort then i turned it up until i found the sound i like.

19 out of what? Do you have a digital multi meter?

if ur talking about the blue wire i ran it from hu to amp then amp to cap. thats my cap in th corner of that pic. grounded to a bolt in the trunk.

i turned the volume setting to 19 on the head unit. i have never been pass 24

Did you sand the ground to bate metal? Where is the bolt? Make sure you have a solid ground and good power. If you do you can set the gain with a test tone. Which way is your sub facing?

sub facing the front of my car with about 6 - 8 inches between the box and the back seat and i keep the little mid arm rest down on the back seat

Turn it around and fire towards the trunk. What about the ground?

whats the max your HU goes? set gains to 3/4s max volume. so multiply .75x(max volume)

and set gain with a test tone. turn your sub around and face the trunk of car about 6" away. i would get rid of the cap if i was you.

i would have to turn it aournd another day. dont have time to do all that now. and i had the cap in my taurus and it stopped my lights from flickering and putting a strain on my alternator so i just transfered it over to my TL with everything else. some say its good some say its bad. i would rather have it tho. but i will turn the box around and see if that makes a diff thanks

Is the ground sanded to bare metal? That is an important detail we're missing

it restricts flow of current to your amp. You are getting less dims but a lot less power at the amp At heavy voltage drops, you are starving the amp of voltage with the cap. Box direction has A LOT to do with how you get loud.IT NEEDS TO LOAD OFF A WALL. Bass needs to bounce and reflect off something solid to even get bass. Go to your EQ settings and turn everything down besides the bass frequencies. then raise the head unit volume because thats what is needed to get a good clean signal to your amps. HEAD UNIT VOLUME. NOT BASS BOOST or cranked gains.

Curious did you build the boxes yourself? Did you buy it online? do you even know how to properly tune a box?

i cant remember if sanded it down or not but if it was an issue with the ground wouldnt it be cutting in and out?

doesnt matter its all part of a proper install which a lot of things you already have done wrong, improper ground will cause future problems. along with current voltage issues.

I had that exact same amp on a type R 2 ohms wired to 4 ohms final getting 500 out of the amp before impedance rise. in a 1.6 cubic feet box tuned to 35hz and my buddy's corolla was getting head liner flex along with jumping water bottles in his car and his mirror kept moving down from the bass. Definitely impressive for a single 12. Was on a stock head unit on a pac Line out convertor too.
