this kit is all quality BUT, the distribution blocks are not fused, both sets of RCA cables are for 2 channel amplifiers. it would have been nice for a dual amp kit to come with a set of RCA's for a 4 channel amp. Also, the fuse for the inline fuse holder is the WRONG type of fuse. the kit includes an in-line ANL mini fuse holder but they supply you with a MAXI fuse??? lol wtf? all in all this kit was not worth it for me, would have been better off buying everything separate this way i would have known and got everything i need and it would have been the same price, seeing how now i have to buy a fused dist. block, mini ANL fuses and a set of RCA cables for a 4 channel amp.
