Reply With Quoteis it bridged?
Alright, kinda disappointed/or i'm an idiot.
I'll start with my disappointment. I just replaced my 300W Bridgeable Kenwood KAC-608S with a 600W MONO Class D Kenwood KAC-6104D.
It isn't hitting NEARLY as hard as the older 300W model.
What did I screw up?

is it bridged?

how do you have the speakers wired up? series, parallel? is it single or dual voice coil sub? how many subs?
if its a class d amp it only has one channel right?

and i thought most class d amps were 1 channel lol
IF you just replaced the Amp w/ this, I'm guessing you haven't screwed around w/ any wiring anywhere else.
Play w/ the Amp settings... Up the Gain or something... Remember, when you have a Amp bridged it does produce more a thump.
Check your HU (head unit) EQ and Amp settings as well....

hold on while i show how i connected the sub to the amp.

I'm the one who originally installed/wired the system, so i'm pretty sure it's correct. I've just never used a MONO amp before.

you sure that's not a 2 channel, my mono only has 2 sub outs,(pos-neg) cause if that's a 2 channel I don't think its bridgeable usually it indicates on the amp where to bridge.
of try moving the pos terminal to the other empty terminal...etc.. try moving those around.
I checked the manual before installing it like a bridge, it showed if only one sub to set it up like that.

UPDATE:
Opened the sub to see if it is the dual or single voice coil model of the MTX Thunder 5500.
It's the single voice coil at 4ohm.
- It seem's to be "cleaner" bass than the old 99' Kenwood.
I have the input sensitivity cranked, and LPF at around 115Hz

its only 4 ohm so your only getting 200 watts. that might be why it isnt that loud
also make sure its bridged
littlerick, my 300W Bridgeable Kenwood KAC-608S was only 150RMS when bridged, so the new amp should be louder at 200RMS.
It can't be bridged since it's a mono AMP, it only has 4 outputs since it can either be used by dual or single voice coil.

Your newer amp KAC-6104D is not bridgable, its a mono amp that can handle two single subs. So its kinda like a dual mono amp. Your older amp has a 300 max with 150rms brigde so im guessing 100 single. So your setup right now from the picture only pushing out 100rms which is of course lower then 150 and why it isnt bumping more like you want. at 4ohm you get about 200rms if you properly connect it. I do need to know the size of your sub cause mtx 5500 makes 4 diff sizes and diff rms etc. Ill explain more when i get this info

mono means 1 you idiot. but there are class d 2 and 5 channels as wellOriginally Posted by littlerick
where did i say mono didnt mean 1? all the class d amps i've ever messed with were 1 channel. thats the first mono amp that i've seen that has a place for 2 speakers.
i see them all the time. the reason why you usually only see class D as mono is because they are very efficient on power but not high on sound quality. Class A is just the opposite.
Yeah I thought it was odd how they show in the manual that you can hook up TWO subs to this MONO amp.
How weird.
