No bass Pt. Deux...

[07ramjam 10+ year member]

First off thanks to everyone who helped me with my first thread.Heres the latest scenario.

I just got back from buying my RD 1750.1 from ztaebevets,thanks Steve what a beauty she is!!!

Anyway, I came home to hook it up and be blown away..well the same problem NO BASS!!!I checked to see if the subs were in phase and they seem to be.Now heres where Im confused.This link shows how to hook up 2 Dual 4's for a 1 ohm load:

Now heres the manual from Alpine,they dont show an option for hooking these up at 1 ohm.As far as I can tell they were hooked up for a 1 ohm load.The manual only shows hooking them up at 4 ohms.I want 1 ohm.

Do you have the remote wire ran? Well the amp does turn on correct?

Hey Steve,

Actually I had everything in my car but I didnt think it was going to be a problem.

The amp powers up and I do get some bass,but the only way is to crank up all the volume and gains.Even then its super weak.

What kind of headunit do you have?

dont got the highpass filter turned on right? lol

and you sure you dont got em wired out of phase? you'd be amazed how much they wil cancel eachother out.. use a 9 volt battery to check...

check the HP, LP and SS filters.

sounds like your woofers are out of phase. make sure you have your +'s together and -'s together. As a test, disconnect one to see if its louder.

Use diagram 2 for 2ohms then tie both speakers together + to + and - to - that will give you the 1 ohm you want. it will be just like the first link.

Im using a Pioneer D3.As far as the HPF,do you mean on the HU or the amp?I have it turned off on the HU.

You guys are getting a little beyond my knowledge.Whats the SS filter and how do it check it?How do I check with a9 volt?

Heres another point of confusion for me.The amp has outputs for 2 subs.Should I use both of them or should I wire it like there is only 1 output?Does this make sense??

SS filter = subsonic filter.

it would be easiest if you took a picture of the amp so we can tell you what to set everything at

you want to bridge the channel, use the positive of one channel and the negative of the other.
