I NTRODUCTION
Rockford engineers designed the Power 150 and Power 200 amplifiers to
withstand the rugged automotive environment while delivering superior
sound quality in a flexible, reliable, and efficient package. TRANS• ana is a
lowvoltagecircuitinthepreampstageletsthemusicsoundcrystalclearand
very real, even when played at high volume levels. This is matched with
TOPAZ, a unique grounding circuit used to eliminate noise problems
associated with car audio systems and their installation. Flexibility is
accomplished with the use of a built-in variable crossover. The use of a
protection circuit called NOMAD, along with MOSFET and DSM (Discrete
SurfaceMount)technologiesimproveamplifierefficiency.Theresultofthese
components give the Power amplifier awesome sound quality in a “Bullet
Proof” package. Explanations of these technologies, most of which are
exclusively designed and patented by Rockford, are described in the
Technical Design Features.

D ESIGN F EATURES
1. Cast Aluminum Heatsink – The cast aluminum heatsink of the Punch
amplifier dissipates heat generated by the amplifier's circuitry. The
inherentadvantage of casting provides a 30% improvement of cooling
over conventional extrusion heatsink designs.
2. Speaker Terminals – The heavy duty, gold-plated terminal block
connectors (+ and –) will accept wire sizes from 8 AWG to 18 AWG.
These gold-plated connectors are immune to corrosion that can cause
signal deterioration.
3. Power Terminals – The power and ground connectors on the Punch
amplifier are gold-plated and will accommodate up to 8 AWG wire
maximizing the input current capability of the amplifier.
4. REM Terminal – This spade terminal is used to remotely turn-on and
turn-off the amplifier when +12V DC is applied.
5. RCA Input Jacks – The industry standard RCA jacks provide an easy
connectionforsignallevelinput.Theyaregold-platedtoresistthesignal
degradation caused by corrosion.
6. High Level Inputs – The high level inputs use a detachable connector
terminatedwith20AWGleads.Theseinputsshouldbeusedifthesource
unit has only speaker line (high level) outputs.
7. Gain Control – The input gain control is preset to match the output of
most source units. It can be adjusted to match output levels from a
variety of source units.

daisy-chaining an additional amplifier without running an extra set of
RCA cables from the front of the vehicle to the rear amplifier location.
9. Punch Bass – The Punch Bass control helps correct for acoustical
deficiencies in the listening environment. The Punch Bass allows a
narrow band adjustment at 45Hz to help reproduce full range sound
without excessive boost.
10. Variable Crossover – The amplifiers have a built-in 12dB/octave
Butterworth filter with a crossover point variable from 50Hz to 210Hz.
The crossover can be set to Low-Pass (LP) or it can be bypassed by
setting it to Full Range (FULL).
11. LED Power Indicator – TheLED illuminates when the unit is turned on.

I NSTALLATION C ONSIDERATIONS
The following is a list of tools you will need for installing the amplifier:
Allen wrenches 9/64" & 3/32" (included) Voltmeter
Wire strippers Battery post wrench
Electric hand drill w/assorted bits Wire cutters
17' (5m) Red Power Wire Assorted connectors
12' (4m) Remote Turn-On Wire Wire crimpers

Thissectionfocuses on some of the vehicle considerations for installing your
new Punch amplifier. Checking your battery and present sound system, as
well as pre-planning your system layout and best wiring routes, will save
installationtime. Whendecidinghowtolayoutyournewsystem,besurethat
each component will be easily accessible for making adjustments.
Before beginning any installation, be sure to follow these simple rules:
1. Besuretocarefullyreadandunderstandtheinstructionsbeforeattempt-
ing to install the amplifier.
2. For safety, disconnect the negative lead from the battery prior to
beginning the installation.
3. Foreasierassembly,wesuggestyourunallwirespriortomountingyour
amplifier in place.
4. Route all of the RCA cables close together and away from any high
current wires.
5. Use high quality connectors for a reliable installation and to minimize
signal or power loss.
6. Think before you drill! Be careful not to cut or drill into gas tanks, fuel
lines, brake or hydraulic lines, vacuum lines or electrical wiring when
working on any vehicle.
7. Never run wires underneath the vehicle. Running the wires inside the
vehicle provides the best protection.
8. Avoid running wires over or through sharp edges. Use rubber or plastic
grommets to protect any wires routed through metal, especially the
firewall.
9. ALWAYS protect the battery and electrical system from damage with
proper fusing. Install a fuseholder and appropriate fuse on the +12V
power wire within 18” (46 cm) of the battery terminal.
10. When grounding to the chassis of the vehicle, scrape all paint from the
metal to ensure a good, clean ground connection. Grounding connec-
tions should be as short as possible and always be connected to metal
that is welded to the main body, or chassis, of the vehicle.
