Will this bundle fit my truck?

The sealed subwoofer box is made for 2019 and newer Ram Crew Cab trucks. The subs, amp and wiring are universal, but the box will not fit other vehicles without modification.

How should the subs be wired to the amp?

Each sub is dual 2-ohm. Wiring the voice coils in parallel gives 1 ohm per sub, and paralleling both subs presents a 1-ohm load, which matches the Krypton M2's 1-ohm rating.

Is the amp powerful enough for both subs?

The subs are CEA-rated at 350 watts RMS each, 700 watts total. The amp is rated 750 watts RMS at 1 ohm, so it is matched on paper, though real-world output may be lower.

What is included in the box?

Two K5 12-inch subs, one Krypton M2 mono amp with remote, a 4-gauge amp wiring kit with RCA cables, a dual-12 sealed box for the Ram Crew Cab, wood screws, 20 feet of 14 AWG speaker wire and four spade terminals.

Do I need an aftermarket head unit?

No. The amp accepts speaker-level or RCA inputs, so it can work with a factory radio, though a line output converter may be needed depending on the truck's system.

What reviewers say

Owner feedback on Rockville K5 subs and Krypton amps is mixed: buyers like the value and the included hardware, but some report the amps fall short of their rated output and the subs are best kept near their RMS rating.

What people mention

ValuePraisedOwners say the bundle covers a full bass setup for less than buying each part separately.
Amp powerCriticisedSome buyers report the Krypton M2 does not deliver the output its peak rating implies.
Sub outputMixedSubs are said to sound good near their RMS rating but distort when pushed harder.
FitmentCriticisedThe sealed box only fits 2019+ Ram Crew Cab trucks, limiting who can use it.
Wiring kitMixedThe included 4-gauge kit works for moderate setups but some installers swap in heavier cable.
