Crutchfield Customer Review (What's this?)

Decent for price

Pros: Price is good and works great for the job.

Cons: Fuse is very large and difficult to hide efficiently. I would expect this from a 120+ amp fuse but not an 80

Easy as it can be

Crutchfield Customer Review (What's this?)

not too much to say here about a aftermarket sub/amp install kit...the kit had everything advertised. i used it with a mtx500.1 mono amp and a JL10" 500W RMS sub. the kit does not come with speaker wire, though i already had speaker wire, so that was not an issue for me, but it's worth noting. i did need to additionally purchase a LOC (line out converter) to tap into the rear factory speaker wires to get signal for the amp. i got the Scosche LOC80 also from crutchfield. both have worked flawlessly together. i'm very satisfied. i gave 4 stars because i don't give 5 unless i can find/get the product for a slickdeal/sale.

Pros: long length of wires, included zip-ties and connectors

Cons: no speaker wire included.

Stranded copper. I never even used the included L/R audio cable. I ran my lightning amp as 5 channel. The lightning 5 channel amp is amazing if you are looking for a great price and want a nice solid sound, and not just some crappy bass thumper. So with what's included in the kit is ONE set of L/R analog cable. It worked great for me. Just finding a place for the fuse holder was a problem. Honda Ridgeline. Very tight engine cabin [ justyn  Oct 29, 2014 ]
stranded copper. very flexible. works fine. soft rubber coating. can be gouged easily with sharp metal things, but I'm a welder and my standard of comparison is 1/0-3/0 black jacket welding cables. should do great for regular stuff. my amp is old school with 90a fuse and I don't push it and have the safety fuse at 80a and cable works fine even in DC heat.
