Salam..
Pioneer Low End bass cannot be compared with kicker.
Same as kicker L7 has far better Sq than pioneer 3001...Particularly 3001d4 SQ 6/10..
Secondly,
Kicker L7 has two very very common problem
1.Blown Coil
2.Tensils breakage(Tillay tout jatay hain)
3.Very short life Not durable subs
4.Require big box
Pioneer on the other hand
1.Very very durable
2.Solid Sub,last for ages
3.Problem free
4.Lack SQ...Play some notes(Low notes)
5.require Average box
Go for ts3004spl(Old ones) far better sub than 3001d4..I have used both the subs for years..
Get a branded amp you will see the difference in power,low Distorstion level at high volumes,Improved quality
