G4500

JL Audio builds their hard-working G-Series amplifiers with the high-end technology that's made their amps legendary. An advanced thermal and low-impedance protection system doesn't shut your amp down when the going gets tough. Instead, it rolls back peak voltage demands to protect the amp, while continuing to play your music at a safe power level. "Differential-balanced inputs" reduce noise by isolating the signal's ground from the chassis ground, making these amps compatible with almost any system, including most factory radios.

The G4500 4-channel amplifier delivers up to 80 watts RMS per channel, and patented Class-AB circuitry delivers exceptional, natural sound with extremely low distortion. Tunable frequency filters give you precise control over your sound, and a switchable bass boost lets you add a little punch when you're driving a subwoofer. The optional RBC-1 remote converts the bass boost into a fully variable control that you can adjust from the comfort of your front seat.

Come on guys, will entertain reasonable offers!

Also, if you want my custom fibreglass box, amp rack and false floor, I'd be willing ot get rid of that too. I dont want to sell the sub atm, but if you really want a full system, I might consider it.

However, the other day, I notice a small crack in the subwoofer, where and umbrella had gone through it. This, strangely, has not affected the sound at all, as it must have been like that for at least a week, but I patched it with som Gaffers tape, and performed some listening tests, and there are NO artifacts.

Sweet! Its a great amp, even if your just using stock speakers as I was, you'll be amazed at how much better they sound. You can also use the four channel to power a sub, using the rears bridged, if you dont get both amps.

BUMP!

Now selling whole system, excludig wiring. 2 amps, 12" sub, and custom fibreglass with false floor. It sounds brilliant, and the box has been overbuilt so is VERY strong.

Without false floor:

I put the carpet that came with the car, and its all protected and I can use the boot to carry all my stuff.

Open to offers for everything, but looking for around $1500 for THE LOT

note as mentioned the sub does have a small hole in it, but it doesnt affect the sound at all, and I just put some gaffers tape on it. I didnt even know it had happenned for at least a weak - a camera umbrella was the culprit.

If you dont want the sub, I'm looking for around $1300

You know me too well Greg

Also, I've stopped drinking Coke, more or less


Move down to a single amp, and a 10" sub, and side mounted like yours so no false floor and hence less weight. And all nice and stealth
