so a while back I bought a set up my buddy had in his caliber srt as my old subs wouldnt fit in the trunk. Its a 10 inch MCD sub, DVC 2 ohms, at 5000 watts max. Its in a ported box specially made for it with a 2000 watt crunch amp for power. had some issued hooking it up but finally got a tiny bit of bump out of it. I had spent 2 days on it and kinda just settled. When it was connected in his srt it was obnoxiously loud and that was with the the amp mostly turned down as well as the settings on the H/U. I currently have everything on the amp turned to the max and like I said its just a tiny bit of bump. The subwoofer bass on the H/U is maxed but when I turn up the separate bass setting on the H/U the sub gets louder but so do the speakers bass and it starts to sound like garbage. bass boost is also on as well.

I tried researching about the issues and it seems to have something to do with the factory amp im assuming? Also saw a few people mention the line/out converter but that seemed to be used for people running into the stock subwoofer wiring.

RCAs run from sub amp to H/U, same with the remote. power and ground normal as well.

let me know what you think the issue is, any help would be GREATLY appreciated. Kinda ready to give up all together and sell the system.

 

How many rca inputs does your h/u have?? Sound like your rca's arent connected to the subwoofet output....

 

Also is your amp on hpf or lpf??

 

h/u has 6, pulling it out as we speak to check where its hooked. pretty sure i remember seeing it say subwoofer when i installed it so thats where i put them. amp has a lpf knob that ranges from 40Hz-150Hz and it was turned about 3/4 to the right.

 

The swutch on the amp is on lpf right?

 

theres no switch. its just a knob. Picture 2 of 7 for P1-2000.1 - Crunch P1 2000.1. and i pulled the radio, the RCAs are connected to the sub out.

 

Any ideas????

 

Well I thought it would be that you had the rca connected to the front or back inputs. But if you have them to the sub output then idk. If I was you I would connect the h/u straight to the battery and see how the sound, and if it sound good then something in the adapter connection must ne wrong.

 

How exactly to you do that?

 

Connect the red and yellow wire from the h/u harness to a 12v source and connect the ground as well. At that point your h/u should turn on. Then put a cd or play something, and if you get bass then that mean something is connected wrong on your adapted harness.

 

did you change anything internally in the box? if u unhook one sub of the 2 what happens

 

its only one 10 inch sub, and no i havent changed anything internally..

 

ok so u only have 1 10" sub. RCA's are to the sub out on the deck amp is set right?

 

Could be bad RCA's.
