FAQ:
(Q). Will Amp Work On Factory Radio?
(A). Yes, But You Must Purchase A Line Output Converter(any audio shop will carry this item). The Only Reason You Need This Is For The RCA Preouts And The Remote Wire To Connect Head Unit To Amp.

(Q). What's Difference Between Mono, 2-Channel & 4-Channel Amp?
(A). Mono Amps Are Made Specifically For Subwoofers, But Other Speakers Can Be Hooked Up To It (Generally Have One Channel, But Two Subs Can Be Ran Off It). A 2-Channel Has Connections For Two Different Speakers(Subs, Speakers) But Both Don't Have To Be Used. On A 4-Channel, Up To 4 Speakers Can Be Connected(Generally For Your Door Speakers). On All These Amps You Can Connect More Than The 2 or 4, But It Is Highly Not Recommended.

(Q). What Is Meant By 'Bridging' An Amp?
(A). When Bridging An Amp, The Positive Wires Are Twisted Together And The Negative's Are Twisted Together, Then Put Into The Amp Using Both Channels. The Postives Will Go To The Left Power, And The Negatives Will Go To The Right Ground (A Ground And Power Will Be Unused).

(Q). My Head Unit Is Satellite Radio Ready, How Do I Make It Work?
(A). Even If Your Head Unit Is Satellite Ready, You Must Still Purchase A Few Extra Parts... Unless Your Unit Came With The Antenna. What The "Ready" Means Is That Your Unit Has The Special Plugin On It For Satellite Radio To Be Added, But The Extra Parts Will Run About $100, And You Must Also Purchase The Ones That Function With Your Brand Of Head Unit.

(Q). What's Difference Between Peak Power And RMS On My Subs/Amps?
(A). RMS Is The Thing That Makes The Difference In Sound And Power. If You Notice, Brands Like Sony Will Slap A Big Number On Front Of The Product... They Do This To Make The Dumb Think It's Big And So They Purchase. When Getting A System, Match Up Your Amp To Your Subs RMS. RMS Is Constant Power To Your Subs, Which Is Turn Is The Constant Power Your Subs Will Produce. Even If The Peak Power Of The Amp Is Quite A Bit Over What Your Subs Recommend, If The RMS Match Up Good, Then Your Alright. Also Be Aware Of Things Like Following (Kenwood KAC-7202 Amp Example):
150w RMS x 2 @ 4 ohms
230w RMS x 2 @ 2 ohms
The 4 Ohms You'll Notice Is Lower, But That's At A Normal Hook Up With No Bridging. The 2 Ohms Will Push More Power, But That Also Means Ya Need To Bridge Your Amp. Bridging Won't Hurt Your Amp, Unless You Turn The Gain/Level All The Way Up(Really Hard On Your Amp, Any Amp).

(Q). My Head Unit Has More Than One Set Of RCA Preouts, What For?
(A). With Multiple Sets Of RCA Preouts, You Have More Options For What You Want To Connect To Your System. For Example, If You Have Two Sets Of Preouts, You Can Run A 2-Channel Amp For Your Subs, And Also A 4-Channel For Your Door Speakers. If You Want To Run Multiple Amps But Only Have One Set Of RCA Preouts, Ya Need To Buy RCA Y's(can be bought bout anywhere.

(Q). I'm Replacing A Factory Radio With An Aftermarket, What Do I Need To Do?
(A). First, You Will Need A Mounting Kit(dash piece), Wiring Harness, And An Antenna Adaptor. You Will Also Need A Crimper/Wire Stripper, And A Few Connection Tabs. The Installation Is Fairly Simple, If You Buy A New Mounting Kit, The Installations On How To Pull Your Radio Out And How To Assemble The New One Is Instructed Step By Step.

(Q). What All Do I Need To Hook Up An Amp?
(A). When Putting In An Amp For The First Time, You Will Need Several Wires, Which Can Usually Be Bought In A Kit From Any Car Audio Shop. You Will Need A Power Wire(from battery to amp), Ground Wire(amp to car frame), Remote Wire, RCA Wires, Speaker Wire.

(Q). What Is A Capacitor And What Is It's Use?
(A). A Capacitor Is Like Another Battery... But Only For Your Amp. If Your Headlights And Interior Lights Dim When Your Subs Hit, Then A Capacitor Would Solve The Problem. A Capacitor Will Help Your Amp Boost, Take Pressure Of Your Battery Supply, Prevent Your Lights From Dimming, And Take Less Pressure Off Your Amp(As Well As Decrease The Chance Of Blowing The Amp From A Power Surge). The Capacitor Splices Into Your Power Wire Between The Amp And Battery.

(Q). What's The Difference Between Co-axial, 2-Way, 3-Way, And 4-Way Speakers?
(A). Your Factory Speakers Are Almost Always Co-axial, But If Your Upgrading Speakers, Then It Is Recommended You Step Up To A 3-Way, Or 4-Way(Unless It's Alpine Or Rockford). With A 3-Way, 4-Way, You Will Get A Better Range Of Sound Because An Extra Small Tweeter(one with 3-way, two with 4-way) Will Be On The Speaker Also. With More Range Of Sound, The Bass Comes Out More Powerful And Cleaner While Also The Treble And The Music Comes Out Cleaner And With Better Quality.

(Q). What's The Significance Of Upgrading Speakers And My Head Unit?
(A). Your Factory Speakers And Equipped For Your Factory Head Unit. Your Factory Speakers Can Only Handle About 15 - 30watts And Your Head Unit Pushes Out Only About 20 - 25watts To Each Speaker. Putting In An Aftermarket Head Unit Will More Than Double The Output To Each Speaker(Usually 45x4 or 50x4), Have More Control Over Your Sound, And It Also Looks Better. Putting In New Speakers(Especially with new head unit), Will Give You An Even Better Quality Of Sound, Everything's Cleaner And Stronger. Aftermarket Speakers Will No Longer Bottom Out, Crackle, Or Fuzz When You Turn Up The Sound. An Aftermarket Head Unit Won't Mess Up Your Factory Speakers, But Putting In All Aftermarket Will Clean The Sound Up A Lot.

(Q). What's Difference Between Single-Voice Coil And Dual-Voice Coil?
(A). Most Typical Subs Are Single Voice Coil, Which Means Is Has One Positive And One Negative Outlet On It. A Dual-Voice Coil Can Be Found On Higher Quality Subs, Or Usually On All High Wattage Subs. A Dual-Voice Coil Has Two Sets Of Positives, And Two Sets Of Negatives. A Single-Voice Coil Is Equipped By Just Running A Postive And Negative From The Amp To The Sub, But With A Dual-Voice Coil, The Sub Has To Commonly Be Ran In A Parallel Or Series Setup. A Dual-Voice Coil Can Handle More Power(more rms), Improves Sub Response, And Gives Greater Sound Range To Your Sub. You Will Be Paying More For A Dual-Voice Coil Sub, And You'll Be Required To Need A Bigger Amp(rms needs to be real close).

(Q). What's The Difference Between Ported And Sealed Subwoofer Boxes?
(A). Some Subwoofers Require A Certain Type Of Box For Optimium Sound, Be Sure To Glance At The Sub Manual First. As For Normal Powered Subs(around 700watts and under), Either Box Can Be Used. With A Ported Box, You Will Get Deeper More Powerful Sounding Bass, But With A Sealed Box You Will Get A Louder Bass Sound. Ported Subs That Are Enclosed(usually in fiber/plexi-glass) Will Give You An Even Better Quality Sound, But Usually Cost A Little More.

(Q). What Are Component Speakers/Setups?
(A). Component Speakers Consist Of Aftermarket Speakers And Tweeters... Which Give The Vehicle A Better Range And Quality Of Sound. Most Commonly, Component Setups Can Be Found With 5.25 And 6.5 Speakers, But Nearly All Sizes Have Had Component Setups Made(takes a little time to find). Using Components Is Like Adding An Extra Two Small Speakers To Your Stereo, Which Can Be Placed About Anywhere(most commonly above or around the doors). Component Packages Usually Have A Much Higer Price Than Normal Aftermarket Speakers, But The Sound Quality Is Superior.
