Hey ive just installed my new amp and sub and im having some trouble it would seem?

When turning the music up it just cuts out >? and also the bass when on is not loud at all infact its very soft? what could be causing these problems im pretty sure its one thing causing the both?

Cheers for your help

What is the gear in question? Model numbers please. Also was it professionally installed?

Did you set it right? What and and sub is it? Probably because your running it on low impedance loads. If you get what i mean.. :S

MTX T4512-04 12" Sub

MTX RT 251-D Mono

done myself

I think maybe the amp hasn't got enough power to run the sub.

4 Ohm Load 100 w x 1 @14.4v

looks like i got done by the salesmen then ey

Very much looks that way mate. Get yourself a nice two channel that you can bridge for at least 200rms @4ohms. I'd be seeing if you can take it back and get something a little better. Always worth a shot.

yea i fixed the volume problem but it still cuts out
i guess underpowerd it is sigh
altho if it isnt and i go in complaining it is im gunna look like an idiot is there anything else it could be?

Check all your connections and make sure your are using an adquate power and ground wire. Might pay to try a different ground point also. Refer to the ground thread that is stickied up top

brett says:
your amp will do whatever it can, your sub wont "require" more power
brett says:
your amp will however require more power if it's underpowered from your battery
brett says:
your sub wont try and use more power than it's given

sounds right? so it might be the power getting to the amp is the problem?

WOAAAAAH
coulda looked liked a fool

its the sub cutting out not the amp.. sooo it could be the wiring inside the box maybe but why would it work when its low and not high
:S

OK
welll one problem brings another

i went in and they exchanged it i got a 200rms amp etc.

NOW i cant get power to this freakin amp i am having the worst day

this is it here http://www.kenwoodaudio.com/australia/prod...&Model=KAC-6202
im really considering giving up and selling it all after this sh*t

Make sure your power wire doesn't have any breaks or anything and make sure the system has a good ground. I had this happen to me, it was the power wire.

hmm i see... i have a power light it seems to be fine? i might trim it tomorrow morning and re-wire it see if that helps

checked all the connections etc still no go

i think its time to give up and count my losses.

Have you made sure you grounded it properly? Power connected up properly with no shorts and connected directly to the battery with 2/4/8 gauge cable. And your remote wire is hooked up and working.

its all the same wiring as the other one which worked fine?

ok i got the light to come on kinda..

when the music is up louder the led flashes fast and strong instead of permenent

when its turned down the light is really weak the sub cut in for a millsecond while i was playing with this

not enuff power from the battery or maybe the remote wire?

8 gauge wire

Sounds to me like you don't have an adequate ground. Try a different point. Being short to keep the wire as short as possible as well as scrapping the paint away from the location you choose.

Also get a multimeter and check that you've got a strong voltage at the amp and like TUN35 said use as short as possible ground thats probably at least 8 guage (I think you said thats what size your using anyway but I'd even go for 4 guage) and make sure it touching bare metal, scrape paint away where your bolting it down. Also check things like the fuse in your bonnet. If the wires aren't nice and tight and the fuse properly seated you might be getting a power light but when the amp goes to suck juice (espically running a sub...base notes) then it may be cutting out. Just for testing forget using the head unit wire and use a good 12 volt source (check with multimeter) and see if that helps. I know it can be a pain but you have to check everything from head to toe. Stick with it
