afrakes Posted February 1, 2012 Report Share Posted February 1, 2012 I have 8 gauge wire running from a previous amp I just uninstalled. I bought a renegade 850 s and it says that 4 gauge wire is required. I checked and the 8 gauge will fit as long as I tighten down the screws enough on my am, but me question is: can I use the 8 gauge wiring I already have installed safely? Or am I s.o.l. and need to run all new wire?

Bump4life Posted February 1, 2012 Report Share Posted February 1, 2012 of course smaller wire will fit into a larger wire hole! duh. can the 8 gauge supply the current for 850 rms. no. that is why they said 4 guage is required. use 4 gauge or larger. otherwise ur amps gunna work hard and get hot, your 8 gauge wire will get hot creating a fire hazard. use 4 gauge Quote Buyer/Seller Feedback Thread: http://www.stevemead...5015-bump4life/ MB C220 153 Trunk Car Build Log: http://www.stevemead...d/#entry1840136 MB C280 Ipad Dash SQ Build Log: http://www.stevemeadedesigns.com/board/topic/194484-bump4lifes-new-benz-tony-c-relay-kit-pictures-ce-electric-audison-front-stage-installed/ My SPL Log: http://www.stevemead...__fromsearch__1 BMW M340 xDrive Stock, for now.

afrakes Posted February 1, 2012 Author Report Share Posted February 1, 2012 The thing is its only pushing 400 watts rms. That's why I thought it might be okay to use the 8 gauge.

Miguels Posted February 1, 2012 Report Share Posted February 1, 2012 whats the fuse rating on the amp?

Bump4life Posted February 1, 2012 Report Share Posted February 1, 2012 well for 400rms you should technically be ok running 8 gauge. YEa what is fuse rating? the thing is if it is trying to suck power, a smaller wire will put more strain on amp. especially for low frequenzy power hungry notes Quote Buyer/Seller Feedback Thread: http://www.stevemead...5015-bump4life/ MB C220 153 Trunk Car Build Log: http://www.stevemead...d/#entry1840136 MB C280 Ipad Dash SQ Build Log: http://www.stevemeadedesigns.com/board/topic/194484-bump4lifes-new-benz-tony-c-relay-kit-pictures-ce-electric-audison-front-stage-installed/ My SPL Log: http://www.stevemead...__fromsearch__1 BMW M340 xDrive Stock, for now.

afrakes Posted February 1, 2012 Author Report Share Posted February 1, 2012 it comes with a 30 amp fuse, was thinking about upgrading it to a 40 though.

afrakes Posted February 1, 2012 Author Report Share Posted February 1, 2012 My bad I just looked to make sure, the amp rating is 25amps x 2 Quote Vehicle: 2014 GMC Sierra 2500HD WT Head Unit: Pioneer DEH- Mids/Highs: Focal Integration ISC 165’s (front) Subs/Amps: TBD Link to comment Share on other sites More sharing options...
Miguels Posted February 1, 2012 Report Share Posted February 1, 2012 if the amp comes wuth a 30a fuse DO NOT put a bigger one, there is a reason to why it has a 30a fuse, running a bigger fuse will hurt more than to help making your amp burn down even before the fuse blows Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
Freshman6969 Posted February 1, 2012 Report Share Posted February 1, 2012 (edited) it comes with a 30 amp fuse, was thinking about upgrading it to a 40 though. the hellllll :No: keep the 30 in there, switching around fuses like that will most likly cause your amp to go up in smoke, and put more strain on your power wire itself, just switch out to 4gauge and make your life easier fucking ninjaed by miguels -.- but still my post applies Edited February 1, 2012 by Freshman6969 Quote Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k! Why would you EVER WANT flex?huh?...flex is what can make the lows lower and more air being pushed correct?
