Car Sound advice

[Nips]

Hi All,

Any car audio fundi's out there?

I have some equipment which I want to put in my car, just not sure how to set it up to make the most of it. I can't decide with to connect the two front speakers to the amp's front channels then the two rears and the sub to the amps rear channels, or connect front and back in parallel to the amps' two front channels (the amp can handle 2 Ohms) and the sub on it's own for the rear. All the details of the speakers and amp are here, although I have attached this as an image as well for readability:

Make Model Size Impedance Rated/Continuous Power Max Power Frequency resp
Front Speakers Sony GT1038 4" 4Ohm 30W 210W 60Hz - 24KHz
Rear Speakers Sony GT1638 6.5" 4Ohm 40W 260W 50Hz - 24KHz
Sub JBL GTO804 8" 4Ohm 200W 800W 30Hz-400Hz

Total Max Power
Amp Sony XMN1004 1000W 2-8Ohm 70W X 4 @ 4Ohms 170W X 4 @ 4 Ohms 5Hz - 50KHz
185W X 4 @ 2Ohms 250W X 2 @ 2Ohms + 500W @ 4Ohms
175W X 2 @ 4Ohms


ANy suggestions?

Thanks

GT 1038's and sub at the back with a crossover at 400Hz wired into back outputs, GT1638's at the front on front outputs. Adjust the gain towards the back back by about 20%, be careful you can nuke those speakers with that amp

Thanks. Interesting you say the amp can nuke the speakers - the guys in the shop said I need to get another amp because this won't be enough - but then they have more of a profit making agenda

Look at the rated power... Ignore max power it's complete nonsense.

If you don't want to use/can't find a crossover wire the GT 1038's as normal at the back and use the sub bridged across both back outputs(+ back left, - back right). GT 1638's wired normally at the front, gain about 10% to the rear.

Well I'm installing this tomorrow:

Digital designs C5C 4ohm: 100W x 4ch, 280W x 2ch
Kicker CompS 300w RMS 4ohm
Phoenix Gold RX65CS 75w-150w RMS

Channel 1 and 2 = Splits @ 100w
3 and 4 - Bridged to sub @ 280W.

I think combining your front and rears on 1 and 2, then bridging 3 and 4 for the sub would work for you. But I'm also Google learned when it comes to sound. So just Google and read as much as you can.

Thanks - I'm also trying to get "Google learned". This car sound thing is quite confusing though - every Google search seems to get different opinions. Will hopefully get to do it this weekend. Look out for the "For Sale slightly melted speakers" post in the classifieds section

It's confusing because it's mostly sheer nonsense. Car sound is characterized by **** amps and even ****ter spewkers all vying for the honour of the highest power claim the advertising authorities will let them get away with.
