sub not loud enough

[sycvs]

hi all just in stalled a new head unit and sub is not loud enough amp is all the way up with boost on and sub and bass is all the way up on head unit was fine on old head unit so just want to know if there is another way to get it louder or can i buy to put b4 the amp or after the amp to increese the sound any help would be great

oh and all i did is swap head unit end of amp unplug from old plug in to new

[Philthy]

Is it barely making any sound, or still going alright but not loud enough to hear from down the street?

What headunit, amp and sub are you running?

[sycvs]

making sound but not like it used to be it was a loud bas and you could have that loud you could not hear the speakers now the speakers are louder then the sub and there not on a amp

[sycvs]

oh and there is nothing wrong with head unit its fine and amp

[sycvs]

its one of them enono ebay dvd 2din and cadiance 350w rms amp and two 12" pro liner 300w rms subs

Sounds like the voltage from the RCA is much lower than your old unit.

Make sure your not setting the gains and bass boost to max on your amplifier or you will be on a fast track towards destroying your gear.

[sycvs]

the amp allready cooked my two 12" 500w rms clarions

can i bridge two subs together on the 1 amp

[Philthy]

Yeah theres a good chance the output voltage on the headunit is much lower than the old one.
So the amp has a smaller signal to amplify and can't get as much volume.

[Fonzie]

The head unit very well may have a subwoofer volume control... Check that.

yes it does and its up is there any thing i can get to amp the signal or would it be better to have two bridged subs

[Philthy]

To amp up the signal? A bigger amp?

That amp won't be big enough to "cook" subs, so if you are destroying them then there is a problem somewhere. I'm gunna point the finger at the fact that you have everything flat out and the subs will be recieveing a massivly clipped signal

[Joe Bellissimo]

You need to amplify the signal mate. You need whats called a Line Driver. I need to check stock tomorrow but I have a model that will amplify the RCA signal for $109.

[sycvs]

so if i get a bigger amp should i get 2 mono blocks or just one 2ch and how many watts should i go to then subs 300w rms

Ahh, I didn't realise they existed. If it is the low output voltage I imagine they would do the trick then

[Joe Bellissimo]

Mate I have sent you a PM with my contact details. This thread is getting difficult to follow, have a chat with me and I will make sure you actually need the Line Driver because I obviously wouldn't want you buying something you don't actually need.

Adjusted the "gain" setting on the amp? someone else suggested this but you havent replied to that?

I agree with most others, the Eonon head-unit might not have a high RCA voltage, which explains why the output has dropped. You didnt touch the subwoofer wiring at all?

yes done gain i think i will need a line driver becouse just tryed my old head unit on it again and it was fine so low rca voltage would be the problem

and what would be better a 2ch amp or 2 mono blocks fro the 2 12" 300watt rms subs just want to know due to wanna change system a bit

[Philthy]

1 big monoblock is generally the way to go

[sycvs]

know of any cheap and i thought you can only run 1 sub of a mono block

One of those should do it. I will take 10% because you are a member or I'll match someone elses prices if someone has a special on them. Whichever is cheaper.
