Only one sub works, help

[Headies 10+ year member]

I have two type-r's each powered by their own 2 channel amp bridged. I originally had 1 amp and 1 sub and it hit hard. I added 1 more sub and 1 more amp. But now, only one of the two are hitting. The other one doesnt move.

This is how it is setup:

The second amp in the series is the only one that powers a sub right now. Sub 2 would hit and sub 1 wouldn't move. I switch the speaker wire from amp 2 to sub 1 and it hit, while sub 2 wouldnt hit with amp 1 speaker wires. I don't know how to set this up or fix the problem.

I have the RCA's coming from my deck to one amp, and another set from the first amp to the second. The subs only respond to the second amp in the series.

Which amp did you add recently? Number 1 or 2? Is it the one that doesn't work?

Have you checked the power and ground wires for it?

The power and grounds are fine. I switched the power from the d-block and the other one worked. Could for some reason the d-block only send power through one of my 8gauges?

maybe you should just get a new D block

is the d block fused? my friend had a fused one and she wasn't getting but six volts to her amp.

So you are telling me that a fuse will restrict the amount of voltage that runs through it??

Edit: didn't realize it was a power problem.

It could if the resistance were great enough ... that would be a really odd scenario, though ...
To clarify ...

Sub 2 + Amp 2 = Sub 2 hits

Sub 1 + Amp 1 = Sub 1 doesn't hit

Sub 2 + Amp 1 = Sub 2 hits

Sub 1 + Amp 2 = Sub 1 doesn't hit

Correct ?

If that's the case, it's probably that sub 1 is damaged ...

i think that is what he was saying. As of lately, I have had a hard time deciphering what a lot of people are trying to say.

.Check your rca's. Try switching your RCA's on your amp. go from HU to output. then, input to output.

to see if your sub ever works if you have a 3 output hu just hook to front or rear. I dunno though.

EDIT: Just found the fuse part. Try switching out the fuse or get a new 1.

^^Still try what I reccomened though.

A fuse is not the problem.

no im saying that her fuse in the block wasnt getting a good connection so it wasnt getting enough juice to turn on

RCA Splitter, y-adapter. your amp might not be passing the full signal to the other amp. LPF might only do high-pass out.

Yep, that was in my Girlfriends Car, the Fuse was blown, but it didnt look blown, it was intact and everything, but when you put a DMM on it, the fuse was only alowing 6 or 7 volts through.

^ Thankyou.

Thats how my buddies was. A gold cap was loose a bit and bam no power.
