Antoni Čović Posted April 2, 2017 Report Share Posted April 2, 2017 Hello, I will be getting FI Q 15 (1.5k rms version) in 4cuft ported 33hz box and I want to know how much clean rms power it can take for dialy use? Thanks Link to comment Share on other sites More sharing options...
Ron36 Posted April 3, 2017 Report Share Posted April 3, 2017 2k wouldn't scare me for daily, I put 1k apiece to my 3 10's rated at 600rms. Got to have have good voltage . 2022 Ford Maverick on 22’s Skar SK1500.1 on 4 Skar VD-8’s Mids Sundown Super tweeters, Skar TX 6.5 components on Skar SKM400.4 LC2 for audio control , XS Power D680 XS Series Extra Battery Link to comment Share on other sites More sharing options...
Antoni Čović Posted April 3, 2017 Author Report Share Posted April 3, 2017 Well, I have hifonics brutus 6000d around 1750rms on 2.8 ohm.. and 3kw+ on 0.7 ohm but not sure if stable. You think that would be okay? and will it be alot louder then my current alpine type r 15? Link to comment Share on other sites More sharing options...
Ron36 Posted April 3, 2017 Report Share Posted April 3, 2017 Don't know not a big hifonics fan very power hungry and don't know how clean there power is but at 2.8ohms not a lot of stress on the amp. 2022 Ford Maverick on 22’s Skar SK1500.1 on 4 Skar VD-8’s Mids Sundown Super tweeters, Skar TX 6.5 components on Skar SKM400.4 LC2 for audio control , XS Power D680 XS Series Extra Battery Link to comment Share on other sites More sharing options...

Now with one type r my voltage doesn't go below 12.8v and it connected on 2ohm. Do you think it's good enough? Link to comment Share on other sites More sharing options...

If you're holding solid voltage I'd have that amp pretty high up on the gain. Feed it some clean power, beat on it, feel the sub, if you think its too hot or if you smell it then turn it down. But I'd start high on the gain and work from there. 2008 VW Jetta Team Fi 12 CT 4000.1 CT 125.4 PWX 6.5 80 PRS EB Flex 2/0 Second Skin ^^^ Build ^^^ Link to comment Share on other sites More sharing options...

I'm getting Q in about week or two.. but just want to make it's worth upgrading Link to comment Share on other sites More sharing options...

Once you get it in and playing you should work on your electrical if you can. Replace batt under hood and group 31 in the back, i'd be you see solid voltage with that amp. 2008 VW Jetta Team Fi 12 CT 4000.1 CT 125.4 PWX 6.5 80 PRS EB Flex 2/0 Second Skin ^^^ Build ^^^ Link to comment Share on other sites More sharing options...

I have stock 75a alternator that i'm not planing on change.. and two 55ah batteries with 0 gauge wires.. amp have 3kw on 1ohm but Q 15 is realistically dual 1.4ohm so I don't know if hifonics will be stable on 0.7 ohm.
