Basically, i have a 1000w 2 channel amp, 2x 1000w subs/speakers, 2x 150w speakers and another 2 100w speakers.

When i connect the 4 speakers to channel A and the two subs to channel B, the fuse in the amp blows up.

I am wondering where i can go about this and would i need crossovers or anything?

Details. Need to know exact model numbers to figure out what is going on.

Off the cuff 4 speakers in parallel would equal a 2ohm load assuming 8ohm drivers and if that is the case it would seem your amp isn't 2ohm stable which wouldn't be surprising for anything other than a high quality professional power amp.

which Amp?
Which Speakers?

- crossover to seperate Frequencies for the Subs and "other speakers" (Tops?) helps a lot
(without would sound nasty at least anyways :)
- 4 speakers per channel might be a bit too much for the Amp
(not all Amps accept loads below 4ohm per channel..)

Yeah thats probley your problem, your maybe driving the amp at 2ohm on one side providing the speakers are 8ohm each,

so your amp probley not built/designed to drive that low, just put/try 2x speakers p/c...

crossover nothing to do with it, its only for basically separating frequencies...doest load amplifiers...

i may just use 2 speakers and 2 subs then, unless there is a possible way to use 4 speakers at 4ohm+?

Basically you're asking an awful lot of a fairly small amplifier. In real terms you are probably looking at it providing about 200W RMS per channel. 2 subs and 2 tops off a channel each is still asking a lot of it, although it depends to some extent on what they are and what music you are playing.

If you want to use a 2 sub/2 top setup properly I would recommend adding an active crossover and another amplifier to your setup and doing it properly.

Something like this will provide a 'real' 500watts per channel. What do you use this amplifier for? Home use or disco's/parties ect?
