I'm into the SQ over SPL sound systems and after enjoying my Soundstream Rubicon 705 for nearly a decade, the smooth, clean and highly versatile JL Audio 450/V2 now takes over the duties of powering my Focal Utopia components and fills my van with the sweetest soundstage I've heard yet. Plus, I get not only SQ (Sound Quality) but some added SPL thrown in as well and good God I'm having trouble describing the detail, accuracy, ambiance, musicality, etc. that is now my favorite listening environment! I've owned Zapco, Audison, a/d/s, PPI, and so on but always leaned towards Soundstream. That is, until I listened to this amp with some skepticism and doubt. After popping in my reference material I was becoming aware of nuances I either overlooked or hadn't distinguished before as the mid range took on a whole new dimension with spacial expansion and clarity. Okay, enough rambling. Bottom line is, give this amp a demo and if you're into progressive metal, fusion type rock, classical compositions, rhythm & blues, classic rock and so forth, than your ears are in for a hearty musical treat! It's established that music is a very subjective matter but when your ears hear things open up, it's like seeing colors in better detail & focus and it's then that you realize that money spent for certain higher quality audio components is a worthwhile endeavor. Paired with matching loudspeakers of the same caliber in quality is key to musical nirvana and JL's newest 4 channel power amp gives you the express lane to reaching that! BTW, I don't work for JL.Read full review
The JL Audio 450/4 is an amazing amplifier. With 150x2 RMS for front speakers and 75x2 RMS for rear speakers it is perfect for powering high-end component speakers that have a little bit lower output sensitivity due to their massive crossovers. I personally have a set of Focal 165K2P's in my front doors and upgraded from a 300/4 to this so I could actually push them to their full potential. If you are looking to buy this amplifier, I would suggest nothing less than 1000/1 to go along with it, a 500/1 just won't be able to keep up even if you crank the gain. Also you will have to upgrade the wiring in your car for this amp. if you don't your high frequency sound will distort due to the lack of volts. You will need to run a deep cycle battery, if not 2. Change the power cable from your alternator to at least 4 gauge, ground your battery with at least 4 gauge, and seriously think about a large capacitor (10 Farads or more). Overall a great amplifier, great sound, great cooling, and great look.Read full review
IT IS POWERFUL,HAS EXCELLENT SOUND,AND IS VERY ATTRACTIVE.IT HAS MANY SETTINGS FOR DIFFERENT TYPES OF SPEAKERS.I HAVE OWNED(AND NOW OWN)MANY DIFFERENT BRANDS OF AMPLIFIERS AND I LIKE THIS ONE BETTER THAN ANY OTHER.I AM NOW SOLD ON JL AUDIO AMPS(UNLESS I FIND ONE ALMOST AS GOOD FOR ALOT LESS).JL AMPS ARE STRONG,CLEAN,AND RUN COOLER THAN MOST BRANDS.THEY ARE ALSO EXCELLENT LOOKING AMPS AND HAVE MORE SETTINGS THAN THEIR COMPETITION.IT IS PROBABLY THE BEST AMP FOR COMPONENT AND OR COAXIAL SPEAKERS,AND IF YOU BRIDGE CHANNEL 1/2 IT IS STRONG ENOUGH TO POWER SOME SUBWOOFERS!THIS AMP REALLY CAN RUN A WHOLE SYSTEM(IF YOU DON'T NEED TWO OR MORE SUBS).JL AUDIO PRODUCTS ARE UNDERRATED SO THEIR 300 WATTS IS REALLY ALOT MORE IN COMPARISON TO OTHER COMPANIES RATINGS.
JL Audio has the best amps and speakers! I have sworn by them in every car I ever owned! I currently have the JL Audio 12w7 ProWedge Box hooked up to a JL Audio 1000/1 amp and a JL Audio 450/4 amp powering my JL Audio VR690-CXI 6 x 9 speakers in the rear and JL Audio ZR650-CSi 6 1/2" Component Speaker System in the front. This is the best JL Audio set up Ive ever done and it sounds amazing and the bass was insane. If your ever going to do a set up like this make sure you do your homework to power these badboy amps, I ende up putting in a 250 amp alternator so I can run the regular car battery and a nice yellow top Optima battery for the system with a 10 farad capacitor else if you don't you will fry your stock alternator!
Lots of tuning options and controls. Easy setup. Terminals for wires hold the wires very cleanly and tight. Only downside is that it is easy to scratch, so it can be a little rough cosmetically if you aren't careful.
