I Need A Little More Detail on Amp Wiring!

ZScr3am · 06-20-2012, 10:23 AM

I have a few questions that I need answered after doing a lot of searching and can't find quite what I'm looking for. No one has really shown how to wire the amp to the speakers because all amps are set up differently. I am a noob at car audio so please forgive me for my ignorance on the subject. I have an Avic Z130bt HU. I'm interested in getting a set up that consist of
Image Dynamics i5800 Bridged, 4 ohms: 180 watts x 2 chan. + 400 x 1 chan. @ 2 ohms.

Image Dynamics CXS64 v.2 RMS: 250 watts per set / 125 watts each side at 4 ohms.

10" Dual 4 ohm IDQ V.3 Series Subwoofer Power Handling:Peak: 1000 watts RMS: 500 watts.

Now I'm curious of how to wire everything up. Please forgive my because I have no idea what the hell I am doing and need great detail. So from what I have searched and gathered is I would take the + input on the crossover to the + of ch 1 on the amp and take the - of the crossover to the - of ch 2 of the amp. Do the same for the other side giving me 125 watts to each side. Then for the sub run + to + and - to - on the sub that would make it 2 ohms and run that to ch 5. Now for the RCA's would I use a splitter for ch 1 and ch 2 to the front left and ch 3 and ch 4 to the front right since I'm not using rear speakers? Or would I use the fronts and rear outputs on the HU harness? This what the harness looks like.

I'm sure I have left some things out, but any input on the subject would be greatly appreciated!! Thanks in advance guys.

You are on the right path. Use good quality spliters to send the front output of the HU to ch 1/2/3/4 just like you said.

Sounds like you have it right, just run the front RCA's to the front of the amp, and the rears from the HU to the sub on the amp. because you have input switch on the amp you shouldn't need any spliters.

the amp should have come with directions/wire diagrams. Check the amp paperwork.

The instructions on the amp are very vague!! I have a subwoofer output on the HU too. Thanks guys.

if you have a sub out use that for the sub for sure.
