SoI got my new amp hooked up yesterday- 2000 Lanzar Vibe 266. and it does ok but i have to crank the volume to where my door speaker practically distort to get some really loud bass. Right now i have them wired to 4 ohms series and I have them bridged on the amp and my amp is 2ohm stable. I was wondering if there was anyway i could make them louder.

 

check all of your gains

 

My gains are all up- could it maybe be somethin with my after market head unit??

 

It could be with your headunit. Check to see if you have seperate subwoofer control on the hu itself. what kind of subs are they, and are they single or dual voice coil. 4 or 2 ohm?

 

Also make sure you have the amp on LPF setting (Low Pass Filter) that way it's only bass going to your subs.

 

What kind of Head unit do you have?

 

How many volts are the preouts? Are they for subwoofers?

 

I have a sony headunit with a subwoofer output and my sub is at +10 on my HU and my subs are DVC dual 4ohms bridged on a 2000 watt lanzar vibe amp. And for my LPF and stuff its set to full. is this ok?

 

Theres a couple of things that I would check for. Make sure all of your connections are solid and that both magnets(DVC) have power feeding to them. Set everything to 0 and start from there. Crossover needs to be set to LPF. Make sure the amp has a little gain.
I have a Sony head unit, and what I did was set the "Loudness" on, the sound pre-set to "Explod", the bass neg, and the treble up on the mids/highs. If it has the option for DSO, set it to 3.

 

On your amp it should have LPF, HPF, FULL.... Set the marker to LPF. On the LPF setting you will get only bass through your sub.
