Wiring Mids and Hi's to a 5 Channel amp

[ilrok]

I installed 2 Polk db651's (coaxial's) and 2 Powerbass tweeters up front and 2 Polk db651's in the rear on my stock system in my 2010 Civic. Now I am looking to wire them up to a 5 channel amp and I want to make sure I do it right. These are the specs for the amp and the speakers;

Amp

Kicker ZX700.5

Specs

AMP1 & AMP2 channels driven

@ 14.4V, 4Ω stereo,  1% THD+N, 70W x 4

@ 14.4V, 2Ω stereo,  1% THD+N, 85W x 4

@ 14.4V, 4Ω mono,  1% THD+N, 165W x 2

SUBWOOFER channel driven

@ 14.4V, 4Ω mono,  1% THD+N, 210W x 1

@ 14.4V, 2Ω mono,  1% THD+N, 420W x 1

Speakers

6.5” Polk DB651 in the front doors and the rear deck

Specs

Nominal Impedance: 4Ω

Power range: 6-60 watts RMS (180 watts peak power)

Frequency response: 35-22,000 Hz

Sensitivity: 92 dB

Tweeters

Powerbass S-1S

Specs

Power Handling (RMS/Peak): 50 / 100 watts

Nominal Impedance: 4Ω

Frequency Response: 3.5kHz-21kHz

Sensitivity (1W / 1M): 92dB

Capacitor value in the inline passive crossover : 5.6 uF

(Has a 0.2 mH iron core coil incorporated to create a 12 dB octave slope rolling on @ 2000 Hz and up.)

I got a harness to bypass the small stock amp and this is the way I plan on wiring it to the Kicker 5 channel.

Amp 1

L+ -Left front speaker + and tweeter +

L- - Left front speaker - and tweeter –

R+ - Right front speaker + and tweeter +

R- - Right front speaker - and tweeter –

Amp 2

L+ -Left rear speaker +

L- - Left rear speaker -

R+ - Right rear speaker +

R- - Right rear speaker -

Would the combination of putting the wires for the tweeters and coaxials on Amp 1 be a issue and damage the amp?

Would it change the impeadance to lower than 4 ohms?

Thanks for your time.

YES! I do not under any circumstance advise paralleling you mid and tweet that way. Tweeters generally have a strange load and paralleling them will really screw with the total load on the channel. What you need to do is get a crossover and wire the tweet and mid into that and then wire the crossover into the amp.

So the inline crossover for the tweet would not enough?

If not, do you know of any crossover you suggest that would not be too expensive?

I've already over spent and do not want to buy components.

Thanks.

Oh sorry bud I didn't realize there was an inline crossover on them, that should be fine then, make sure you dont push more power to them than they are rated for tho just to be on the safe side

So, just to be safe, this is the way I wire them at the amp terminal.

Amp 1

L+ -Left front speaker + and tweeter +

L- - Left front speaker - and tweeter –

R+ - Right front speaker + and tweeter +

R- - Right front speaker - and tweeter –

Amp 2

L+ -Left rear speaker +

L- - Left rear speaker -

R+ - Right rear speaker +

R- - Right rear speaker -
