Amp Bridgeing Question

[stylez777 10+ year member]

I was contimplating bridgeing my amp to send more power to my comps in the door. I am very new to this and was reading a bunch of posts and got confused. Looking at the manufactuer specs it can be bridged into a 3x400 @4ohm (doesn't say stereo so assuming it's mono).

on the amp the channel terminals are up and down as follows (First one listed is the sub channel then it goes channel 4,3,2,1):

L R- L+ R- L+

R R+ L- R+ L-

Now to wire this up the left door speaker would go to L+ R- on chan 1&2 and the right door Speaker would go to L+ R- on chan 3&4? is that correct? also do I keep the RCA's the same like Front L out to Front L in etc etc or do those need to be changed up to get it to work in stereo? (Not sure how it will sound in mono compared to stereo) So you can see i am a bit confused and help would be appreciated don;t want to wire somethign wrong and screw myself.

Wow, way too confusing. Give us the make and model of the amp and make and model of the components... then we can help.

the make of the amp is an earthquake model 900w.5 the components are cadence CVL-6k.

It is a bit confusing so you can see my dilema! lol but there is 5 channels from left to right first one is the sub channel then it goes channel 4 then channel 3 channel 2 channel 1. The wiring series is up and down so for example channel 1 would be L+ on top then L- below it. hope that kinda clears it up some, I read that to bridge it your suppose to connect L- R+ for one speaker then L- R+ for the other speaker (assuming i am using channel 1& 2 then Channel 3&4) I'm probably confusing it even more. So a rough explination on what im suppose to do would be good and maybe clarify if i'm bridgeing this in mono what affect it's going to have on the sound and if there is a way to bridge it in stereo. Any help is appreciated.

My purpose is to get more power to my front components. My amp is rated 4x130 1x400 @ 4ohm, 4 x 240 1x 500 @ 2ohm and 3 x 400 @ 4ohm bridged.

Before I did all this I figured bridgeing the amp would be viable so i could send 400 watts to each of the fornt speakers and then send 400 to the sub (of course i'd be way over powering the front speakers but fig i could set the gains to get the desired amount of watts) after doing more reading and seeing that it would be mono going to my speakers seems like it's not a good idea.

My head unit has 4v preouts and i believe the amp has max 5v inputs, think i read somewhere that the HU wouldn't be able to fully suply the amp with the desired volts so the amp could suply the desired watts cleanly to the speakers. meanign i'll never get the full wattage from the amp. this true?

Anyhow, more reading lead me to possibly wiring the speaker in parallel mode to so the amp would run a 2ohm impeadance (which it is capable of doing) so I can get the more watts I want to the front speakers. I read that wiring 2 4ohm speakers in parrallel would create the 2ohm load on the amp. So my questions would be:

1: Would this be ok to do since they are not 2ohm speakers?

2: To wire them parallel would be just taking the positve from both speakers and the negative form both speakers and connect them to the pos and neg of just 1 channel?

3: Wiring them up like this affect when i add my sub? Would i have to wire that for 2ohm also or would the amp be able to do both at the same time?

4: Assuming i am correct on question 3 would this be a waste to do since i'd have 3 open channels with nothing to use them for?

Very newbish questions I know but i'm trying to learn as i go and the more i read i think the more the info is meshing and I might not be fully understanding. Again any help is appreciated.
