Slash 3 Review

I recently helped build my buddys system. He is using 2 of these on 2 W7 12s. Sounds great, no complaints except the HEAVY pricetag. Amp is durable and sounds absolutely amazing. He could have saved alota$ buying RFosgate i think, but it wouldnt sound as clean. If you want really loud and pretty clear get RFosgate. If you want loud and really clear get the JL. These things imo should be about 550$ would be a good price. My buddy just has alot of $$$. I personelly run W7s and Fosgate gear. Always jl speakers and fosgate amps i have found the best. Better have an xs power battery and atleast a 200amp alt as well cuz the Jl sucks alot of juice.

Quality sound

I have alpine SPR-60C in my doors and back panels, with a JL 300/4v3 running the high end. The low end is run by two JL 1200/1v3, each amp powers 1 alpine type X 12" sub. This is one of the cleanest sounding systems I have ever had. Lots of base, and I haven't even punished the subs yet. I still have to put in my 250 amp alternator.

JL Audio 1200/1v3

This amp is a monster it sounds clear and clean and will pump massive bass that's unexplainable and it needs a lot of power, it is expensive but its worth every dollar and will last for years and will not back down from no subwoofer it will blow any sub that has a weak voice coli this amp is built by the best audio company period, I had the 1000/1v2 and the v1 and they are out of this world, but i suggest a high output alternator and a deep cycle battery or your car won't last a week, and 0 gauge wire only, the best amp on the planet is back in black.

Great Amp

I have one of the old versions of this amp and it smoked 12 12 subwoofers in a month. I have this thing pushing two pioneer ts-w5102spl and it does not back down. would recommend this amp.

Awesome amp real power

Awesome amp. I didn't buy from sonic got it at my local shop which is an authorized jl audio dealer. Before this amp I had the hifonics brutus 2000 watt amp. Nothing against that amp I think hifonics is an good amp I have a review for that on this site as well but there is a big difference in the sound coming from the brutus amp and the slash from jl. Sound quality is out of this world true pure real power. Gave a demo to my co-workers and they were amazed have it pushing 2 jl w6 12's which also are amazing. YOU will need to upgrade alternator and get a second battery it eat up some power!!! It's an beast heavy and durable and huge but have an 2003 mercury grand marquis all custom install amp rack and etc.

power house

This amp is amazing i had 1200/1 v2 and a pair of 13 w7 woofers on it and pushed them all day long just wish the price was cheaper.

WOW! BEST SUBWOOFER

I just got these installed today and i was blown alway these are some beastt subwoofer they are veru loud and clean i had 2'12s kicker comp R they are trash these subs will kill any ofther subwoofer str8 up... I recommend these if you want loud bass and have ya car shaking and be heard couple a block away.

The best amp ever!

I've got the Slash 1000/1 and it is every bit of what I wanted from an amp. It's regulated power supply allows this amp to push the same amount of watts no matter what impedance you are running at. Fully loaded with all the features of any modern amp except JL has been making this amp for over 15 years and it is still 1 of the best selling amps of all time. I'm running mine at 4ohms and it barely gets warm after pounding for hours. It delivers clean power allowing you to push more of it w/ less noise at unwanted frequencies and getting the most out of your subs. I bought 1 of these way back in 2003 and it is all I will buy from now on until someone else makes something as good but I haven't seen it yet. It's aesthetically the best looking amp but it's performance is unparalleled. No longer do you need to wire down to the lowest impedance and squeeze every bit of power from your amp straining your vehicle and system. It's not necessary. If $ is not an issue just buy the right amp from the beginning and get the Slash, there's not a better option that I know of. Old school prices ($1 a watt) but Old School performance and an amp that'll last 20+ years.

my new bad boys

Just purchased a pair of massive audio summo's 124... i havent bought the belva 5000 watt amp sonic recommended...so for now i have them on a hifonics brutus 1606d super d-class with only 1600 watts and they sound super...very nice deep low's...cant wait to get my belva amp...thank you sonic- great quality products and pricing along with customer service !!

summo uch pounding

The only thing I can say is WOW!! if you have the power to feed these subs. you will understand the WOW!!! I have recently purchased the hippo, Have not install as of today 1-5-2016. If they are built like the summo I have will be beyond pleased. They are glass breakers..

Great experience from beginning to end

All I can say is wow this sub is a beast this is a very very impressive subwoofer power hungry but if you have the juice to push these subs you are in for a treat. 4 weeks in and the sub is just hitting it's peak sounds great I have had kicker jl w3 has both beat. You cannot go wrong here I'm only feeding it 1000 watts and handles all with no problem no distortion no clapping just very low clean sound

UNEXPECTED

I wasn't expecting this to be so clean and smooth reminds me of a beefed up polk mm sub. Its very clean and smooth on higher end freq which I really enjoy. It's power hungry you need atleast 1500 rms clean unclipped to really open these up. I thought id get away with 1000rms since the subs efficency is so high at almost 94db but it needs more so if you buy this trust a stranger at give it bare minimum 1500 true clean rms not a cheap hifonics 1500rms get a cea certified quality amplifier thats efficient and enjoy this clean low loud monster. This is not just a spl sub.
