Head:Pioneer DEH-P77DH(Want to fill GM space)
Front:Infinity Kappa Perfect 6.1 6.5" Components(100RMS)
Rear:Infinity REF9603I 6"x9" 3-Way Speakers(100RMS)
Amp:Profile Clarus CL640(110W RMS x2 @2ohms)
1st, Let Me Say That I Listen To The Same Type Of Music As You Do! I DONT Do Rap Music and DONT Require The Neighbors To Hear My Body Panels Rattling As I Drive By. I've Allready Been Thru This Whole Senario Of The Type Of Setup Your Looking For And Here's What I Came Up With:
(1). The Pioneer Head Unit Is a Good Choice!
(2). The Kapaa Perfect 6 1/2 Components, Also a Good Choice With Hacks Door Speaker Adaptor.
(Here's The Link And Their Easy To Make)
Hacks 6 1/2" Door Speaker Template
(3). The Infinity Reference 6X9'Speakers Are a "Mis-Match For The KaPaa's In The Front Door.
Rule Of Thumb Is: Try To Match all 4 Factory Speaker Locations With The Same Type and Series Of Speaker. I Suggest You Install The Infinity Kappa 6X9 2 Way's Or 3 Ways In The Rear Deck.
(4). The "Profile Clarus CL640" Amp Is NOT a Good Choice But It Will work For This Setup! Run It At The Rated 75X4 @ 4Ohms If You Choose To Buy It? It's Just a Lower Quality Amp!
All 4 Speakers You Want To Install Are Rated at 4 Ohms and Should Be Run At 4 Ohms, Not 8 Ohms or a 2 Ohm Load (A Series or Parallel Wiring Setup)..... (Their Not Subs and Recommended To Be Run At Their Rated 4 Ohm Load). In Short, You Need a 4 Channel Amp That's Rated a 4 Ohms Per Channel and 50 to 75 Watts Per Channel Will Be Plenty For This Setup (Again, Were Not Driving Subwoofers Here). You Will Get "Decent" Bass Response Out Of The 6X9's For The Low End Fill. Even At 50 Watts Per Channel (What I Have) Your Ears Will Be At The Threshold Of Pain When You Crank It Up! I Also Suggest You Put a Layer of "Dyna-Mat" On The Underside and Topside Of The REAR Speaker Deck Around Your 6X9's Because The Sheet Metal Tends To Vibrate Back There and Annoyed The Hell Of Of Me Until I Did It! Buy a 4 Way Amp With Built In Crossovers (More Important For Your Front Speakers Here). Suggestions For Or 4 Way Amp For This Setup:
(The Key Here Is To Get an Amp With "Variable" Crossovers, Not "Fixed Crossovers).
(1).Alpine MRV-F340 (55 Watts X4 @ 4 Ohms)
(2).Audiobahn A4401T (55X4 @ 4Ohms)
(3).Rockford Fosgate Power 551X (70X 4 @ 4 Ohms)
(4).Autotek SS400.4 (70X4 @ 4Ohms)
Just Remember, The Quality Of The Amp You Choose Is Important Also! The $99.00 "Class A" Amps You See Out Their Are Mostly Junk! Buy An Amp That's At Least Class A/B. All The Amps Listed Above Are Class A/B And Range In Price From $175.00 to $245.00 You Can Find Any Of These Amps For Sale Cheaper On E-Bay Than Say,At Crutchfields.
