I have a kenwood kdc 7202 I think... not sure... but its kenwood. I keep blowing damn fuses! Its a 2 channel amp with capibility to be a mono amp, so I have it bridged and in mono mode. It worked great for a while. But now it keeps blowing fuses every other day. Could it be because my settings are up to high? I turned the gain down and it allowed it to hold fuses for longer... should I turn the gain down more? whats a good number to put my hpf and lpf(if thats what it is, lol) on?

a two channel amp can only handle a 4ohm load bridged, so if your sub is 2ohms, too much current is running threw your amp and it blowes your fuse. what is your sub and how many ohms? do you mean the fuse on the amp or the fuse under your hood?

if it's the fuse under ur hood, go and get a 100 mpa circuit breaker by Monster Cable, i got one and it works great!

lol no thats the worst advice ever. theres a chance you can set your trunk on fire with a 100 amp cb. in general you want 10 amps per every 100 watts rms. so if you have a 200 watt rms amp you want a 20 or 30 amp fuse at the most. otherwise theres something wrong with your set up. something can be grounding out. you could be running ur amp at the wrong ohm load. you could just have a bad amp. but fuses and cb arnt useless they are important components/gauges that let you know when somethings wrong. so for your kac7202 i would go with a 50 amp or 60 amp fuse. if it keeps blowing check out all your wires. you want 4 awg if your running that much power too.

The fuse on the amp. And my subs are 4 ohms each.. I have two 12's. Think if I turn the settings down it'll work better?

that's your problem, you have two 4ohms subs in parralell (wich makes 2ohms load on your amp) in bridged mode, your amp can only handle 4ohms. you need to bridge it in series or hooking up the subs one on each channel, but you will only get half the power your amp can deliver because you'll be running at 8ohms. When you have 2 4ohms subs, you should get a mono amp instead of a 2 channel amp because a mono can handle 2ohms and then you would get your full amp power when hooked up at 2ohms. If you need to know what parralle and series mean, let me know and I'll describe it for you.

yes... please explain.

here is series and paralelle. you should put it in series. But you will only have half the power your amp can deliver, so i'd get a mono amp (then you would push it to it's potential) or get 2 DVC 4ohm subs and then you'll be able to hook them up in a 4ohm load.

Blahman240

which is series and which is paralle? I don't understand...

Blahman240

oh... I see.
