my subwoofers arent hitting as hard as they should

[spenceyadigg]

i have 2 12" rockford fosgate punch2 in a box with a 3000w amp. i also have a jensen vm9312 headunit. i took them to a local car audio shop to get them installed but after the guy finished he said he hooked up my subs to the rear speaker outputs because my headunit only had a single subwoofer output. my subs dont seem to hit as hard as they could and i was wondering if this is because they are hooked up to the rear speakers. how can i get my subs to hit harder? thanks for the responses

He used a LOC, I had that problem with my friends stock stereo, so we bought him an aftermarket stereo and now it sounds great.

The great question remains... why didn't he use the subwoofer output? I'd ask for a refund, dude is clearly an idiot.

WHat amp do you have?

 

[spenceyadigg]

my head unit has 5-channel preamp outputs (2 front, 2 rear, 1 sub). the rca cables dont fit into the 1 sub output so he connected the subs to the rear. would connecting them to the rear lower the bass though?

???? How do the rcas not fit?

Is low pass filter set on the amp?

 

[n2caraudio 10+ year member]

Also make sure that the head unit doesnt have a high pass filter turned on. Or just use a rca y connector and plug it into the sub out

Use this...

Yes, that.

Use this...
