krazz619 Posted December 11, 2017 Report Share Posted December 11, 2017 Sup SMD Forums, I've been thinking a lot about my current sound system and what to do next. Money is tight so trying to make the right choices here. So in my '15 tC I got a Rockford T2D215 hooked up to a Skar RP-1500.1d, with stock battery 530cca, and stock 100amp alternator with Big 3. The way my amp is tuned I still don't know 100% if I'm getting full potential because I don't know my headunit max clean volume level. Still sounds really good though, no overheating, burnt smells, and no distortion. So I wanna get a bigger amp for this one sub, currently looking at RP-2000.1 and BRX-2400.1 I wanna know what I need to do for electrical to support it. I've always preferred having a single battery so was wondering if I can manage that. A high output alternator costs some money but can I manage with my stock one Still? If I stay with my stock alt, is there a single battery that'll work or is a secondary required? Picking a secondary battery has been difficult mainly because I don't know how much more amps I need, and also I have no idea how I'll mount it since my box takes up 90% of space. If I can't get answers then just mention what numbers I need to look for and what math I need to do. I built my own box so I can figure some things out but I don't remember everything now and I'm gonna have to relearn when I make a new box lol. Purpose of this post is for advice, discussion, and maybe help others that are similar to me.

alex912005 Posted December 11, 2017 Report Share Posted December 11, 2017 If you wanna have a single battery get a big group 31 agm, if you have the space under the hood. You'll probably be dropping to 12 volts or less. Also those amps are kinda on the cheap side. I would get an amp that has a clip light on the gain knob. This way you know when you're getting full potential and when you're clipping. My Build Log Link to comment Share on other sites More sharing options...

Also that clip light on helps me tune the amp, I still don't know what volume for my CDA-105. Waiting to find someone with a SMD DD-1. If anyone near Vista, San Marcos, Carlsbad, CA area with a DD-1 hit me up please? 2015 Scion tC DieHard AGM Battery, Stock Alternator, with Big 3 Alpine CDA-105, Hertz Energy 6.5" 3 Way Components, Skar TX65 Coaxials Rockford Fosgate T2D215 Skar RP-1500.1D and RP-150.4AB Link to comment Share on other sites More sharing options...
SkarredSierra Posted December 11, 2017 Report Share Posted December 11, 2017 That amp should be perfect for that woofer. Get a dd1 and do it right. Clip lights on bass knobs are not acurrate. Also get the biggest agm u can fit under your hood and another large agm in the rear. But honestly the best thing is a ho alt. Link to comment Share on other sites More sharing options...

But honestly the best thing is a ho alt. 1500 is good for the sub but I feel it can easily handle a lot more. Yeah I'll have to see what batteries I can fit and just pick one. And yeah I do wanna tune my setup properly before I get something, all the DD-1s are sold out so I'm trying to find someone nearby that has one I had my friend tune my amp with a DD-1 but we just set it to whatever volume level we felt like because he said we couldn't find the max nondistorted volume level without a speaker amp (not my sub amp). Which is wrong I believe so that's dumb.. 2015 Scion tC DieHard AGM Battery, Stock Alternator, with Big 3 Alpine CDA-105, Hertz Energy 6.5" 3 Way Components, Skar TX65 Coaxials Rockford Fosgate T2D215 Skar RP-1500.1D and RP-150.4AB Link to comment Share on other sites More sharing options...

SkarredSierra Posted December 12, 2017 Report Share Posted December 12, 2017 If u do feel like upgrading i do think the skar rp2k will suffice. For the price and power id choose it over most other 2k amps. Ive ran my skar amps for a while now with no issues. Link to comment Share on other sites More sharing options...
