Advise with wiring eight 4ohm loads

[x91evo 10+ year member]

Elemental Designs Nine.5:

RMS Power @ 12.5v : Front Channels

4 x 100 @ 4Ohm @ 0.05%THD

4 x 55 @ 8Ohm @ 0.05%THD

4 x 175 @ 2Ohm @ 0.05%THD

2 x 350 @ 4Ohm @ 0.05%THD

RMS Power (Subwoofer Channel) @ 12.5v :

1 x 250w @ 4Ohm @ 0.09%THD

1 x 450w @ 2Ohm @ 0.09%THD

1 x 600w @ 1Ohm @ 0.09%THD

I am on 16.5 volts charging (YES this amp can handle this voltage)

so I figure the real power will be a little more..

I went with 2 sets of Rockford Fosgate T2652-S components

Each of the 4 tweeters (4ohm) is rated at 100RMS and 200MAX

Also each mid (4ohm) is rated at 100RMS and 200MAX

The nine.5 has crossovers built in for channels 1-4

but also the rocksfords came with 4 crossovers that have a protection circuit for the tweeters.

Could someone help me decide how to wire this please?

I went over every variation on paper and cannot seem to figure out something that works

Series parallel would put my amp at this?

2 x 350 @ 4Ohm @ 0.05%THD

wouldnt that make it instantly bridged? since there would only be two of the four channels used?

im a noob to electronics.. :,(

2 set of speakers per channel @ 2 ohms. Run tweets off front, mids of rears. Sub for sub if you have one.

You better get ready for that amp to get warm playing a 2 ohm load through all channels.

If you have two sets of components, why not simply run one to each channel, using the passive crossovers included, like you normally would?

 

[x91evo 10+ year member]

yea but I have 4 tweeters @ 4ohm

and 4 mids @ 4ohm

do not want to overpower them

you designed me a box! you still have that thread active I got some pictures

@RAM_Designs

because the 4 crossovers supplied have two sets of inputs one for tweet, one for mid
so to do that simple stuff I would need 8 channels?

 

[x91evo 10+ year member]

8 speakers at 4ohm

4 channels at 100watts rms each

one sub channel 600watts at 1ohm

or 350 at 4ohm

Bi-ampable crossover?

And ya my thread is still active: http://www.caraudio.com/forums/buck-box-designs/535560-bucks-box-design-pics.html

you tell me haha

and i will get right on that

So how many crossovers do you have and what power can they handle?

 

[x91evo 10+ year member]

it came with 2,

1 per each mid/tweet

in addition crossovers are internal in the amplifier already

 

[x91evo 10+ year member]

in total my setup has 4 external crossovers

4 mids

4 tweeters

sorry if im confusing lol

and then the internal crossover in the amp itself

POWER Speakers - T2652-S - Rockford Fosgate®

Does the amp have bandpass crossovers for each channel?

 

[x91evo 10+ year member]

looks like it pairs 1,2

then 3,4 together with the bp?

i was thinking i dont really need the rockford crossovers?
